CHAPTER 1

1 Introduction Pipe routing is probably the activity that consumes most time on any large project and it is also one, which causes the most problems. Pipe routing in PDMS has always been one of the major strengths of the system, as you will discover in this module. 1.1 Aim

The aim of the course is to provide the skills required to use the PDMS Piping Design application in the most productive way, to introduce some of the techniques that are used in the other Design applications and have an understanding of Piping components, routing, checking isometrics and simple Clash detection. 1.2 Objectives

At the end of this Piping Design training course, the participants will able to:

Understand the basic concepts of Pipes and Branches. Understand the use of piping specifications in AVEVA Plant. Understand the concept of branch heads and tails and the importance of component list order

and flow direction within a branch. Create position and orientate piping components. Orient and position components in falling pipelines. Apply Insulation and Tracing to the pipelines Use more complex positioning with relation to other design items. Run Data Consistency Checks to screen or file including Parameters and Tolerances and to

understand most of the diagnostic messages. Perform simple Clash Checks Perform Check Isometrics. Create and use Piping Design Assemblies. Understand pipe splitting on components or by using Assemblies.

1.3 Prerequisites The participants must have completed the PDMS Introduction and Basics course. 1.4 Course Structure Training will consist of oral and visual presentations, demonstrations and set exercises. Each workstation will have a training project, populated with model objects. This will be used by the trainees to practice their methods, and complete the set exercises. 1.5 Using this guide Certain text styles are used to indicate special situations throughout this document, here is a summary; Menu pull downs and button press actions are indicated by bold dark turquoise text.

CHAPTER 2

2 Pipework Modelling The following Chapter describes how PDMS is used for modelling pipework. There is a separate design hierarchy for pipe routing, as shown below. In principle, each pipe element may own a number of branches. In turn, branches may own a number of piping components like valves and reducers. The difference between pipes and branches is that a branch is only considered to have two ends, while a pipe may have any number of ends, depending on the number of branches it owns.

Below shows a pipe with three ends and two branches. The second branch is connected to the first at the tee. This brings in another rule that says that although a branch only has two ends, it may own components (in this case a tee), which connects to other branches. These simple concepts enable any number of piping configurations to be developed, and form the basis of all the PDMS Pipework you will encounter.

Alternatively the branch could leave the tee through the offline leg as shown.

2.1 Entering a Design Session To start the PDMS application, Select All Programs > AVEVA > PDMS 12.0 > Run PDMS

Your Trainer will provide a shortcut User Name and Password to PDMS but typically it will be as follows:

On the AVEVA PDMS Login box, enter Project SAM Username USERA Password A MDB TRAINA Module Design and then click OK

A default screen layout will be displayed comprising the general menu bar for the application and a Design Explorer window showing all the objects from the current project database. You can reposition and, in some cases, resize Designs windows. If you select a named file from the load form selector then the screen will be returned to the layout at the time of saving.

Once the Design application has been started, check that you are running in the Pipework application, this can be seen on the top of the design framework, if it does not say Pipework Application, then select Design > Pipework, this will then change to the correct application.

2.2 Piping Specifications In the same way that design offices have standard piping specifications, PDMS has a set of specifications from which you can choose. In fact all the components you will use in PDMS must be defined in the Catalogue and be placed in a Specification before you can use them. In the Training Project there are three such specifications:

A1A = ANSI CLASS 150 CARBON STEEL A3B = ANSI CLASS 300 CARBON STEEL F1C = ANSI CLASS 150 STAINLESS STEEL

These specifications contain all the fittings you will require for the course exercises.


13

www.aveva.com

2.3 Setting the Appropriate Specification The first task when building a pipe is to decide which specification you are going to use. For the Training Project, the first letter in the pipe name represents the specification to be used. For example, the pipe /150-B-5 has the letter ‘B’ to represent the specification. The specification letters are as follows: - A = /A1A B = /A3B C = /F1C Having decided on the appropriate specification, this is then set as an attribute of the pipe. Any subsequent branches will automatically be assigned with the same specification (although this can be re-specified if required). When you enter the Piping Application the Default Specification Form is displayed. The default Insulation and Tracing Specifications can also be set using this form but are only active when ticked.

2.4 Pipework Toolbar The Pipework Toolbar is used to Manipulate Pipes, Branches and Branch Components.

The default Piping Specification can be reset using this Icon.

2.5 Pipe Creation Form To Display the Pipe Creation form, select the Show pipe creation form icon from the Pipework Toolbar

The Create Pipe form is now displayed Pipes hold reference data i.e. Insulation and Tracing Specs, and also the Temperature and Pressure of the pipe. Before creating the pipe we must first navigate to the correct zone using the Design Explorer, The Bore field indicated on the form is the nominal bore for this pipe and does not affect the pipe route.

2.6 Pipe Branches Branches serve two purposes:

• They define the start and finish points of a pipe route (known as the Head and Tail in PDMS). • They own the piping components, which define the route.

The position and order of the piping components below branch level determine the physical route. In PDMS you only ever need to consider the fittings, because the pipe that appears between fittings is automatically set (or implied) by PDMS according to the specifications of the fittings.


15

www.aveva.com

2.7 Pipe Branch Heads and Tails All branches need to have a start and end point. These can be a position in space (3D co-ordinates), the flange face of a nozzle, a tee or various other points in your design. Heads and tails are set up via a series of attributes that belong to the branch element.

Note the Branch head is at the face of Nozzle 1 and the Branch Tail is at the face of Nozzle 2.

2.7.1 Attributes for heads of branches HPOS The position in the zone where the branch starts. HCON The connection type of the branch end (Up to a 4 character code for flanged, butt weld, screwed, etc.). HDIR The direction in which the start of the branch is pointing (as if you were looking down the bore). HBOR The bore of the pipe (this can be metric or imperial). HREF The name of the item to which the branch head is connected (e.g. /C1101-N1). If this is not set, then the branch is open to the atmosphere for a vent or drain. HSTU This is a reference to the catalogue, which determines the material of the first piece of pipe, between the start of the branch and the first fitting (this still needs to be set, even if there is a fitting connected directly to the head).

2.7.2 Attributes for tails of branches TPOS The position in the zone where the branch ends. TCON The connection type of the branch end (Up to a 4 character code for flanged, butt weld, screwed, etc.). TDIR The direction in which the end of the branch is pointing (as if you were looking back down the bore). TBOR The bore of the pipe (this can be metric or imperial). TREF The name of the item to which the branch tail is connected (e.g. /150-A-3). If this is not set, then the branch is open to the atmosphere for a vent or drain.

You do not need to specify each of these attributes every time you create a branch. On most occasions when you set a head or tail, you will be connecting to another pipe or to a nozzle. The act of connecting to another item sets all the attributes at once.

A Pipe is just an administration element it is the pipe Branch that holds the geometry. When you select Apply on the Pipe Form the Modify Pipe form is automatically displayed so that the branch head and tails can be specified.


16

www.aveva.com

2.8 Pipe Branch Head / Tail Positioned Explicitly After clicking the Change button on the Head Detail pane above, the following form appears:

When setting the Branch Head or Tail explicitly you need to specify each of the previously described Branch attributes. Bore: Nominal Bore size of the pipe. The pull-down list contains all sizes available in the specification. Connection: Short code eg: FBB,FBD defining the Head connection type Position: Position in world co-ordinates The Head Direction is the direction of the flow and the Tail Direction is opposite to the flow.

Refer to the AVEVA coding standards for a full definition of connection types.


17

www.aveva.com

2.9 Pipe Branch Head / Tail Connected Use the Change button on the Head Connection pane to connect the head to another database item, e.g.: Nozzle, Branch Head/Tail, etc

Using the graphical Pick Button, select an item to connect the pipe head to. A list of available connections form is displayed, Select the appropriate connection and then press Connect.

This sets the pipe head attributes HPOS and HDIR

2.10 Pipe Branch Components (Pipe Fittings) When you first define a head and tail for a branch, your branch will consist of one piece of pipe running in a straight line between the head and tail positions. This will appear as a dotted line between the two points unless the head and tail are aligned along a common axis and have the same bore. (The dotted line indicates that the branch route is geometrically incorrect.)

The next step in designing a pipe is to create and position a series of fittings, which define the pipe route you require. Just as on a drawing board, you need to decide which piping components are needed in order to satisfy the requirements of the process. The components must be arranged so that the pipe meets its design needs. However, unlike on the drawing board, you do not need to know any fitting dimensions; PDMS derives these automatically from the catalogue. To create components, you need to select an item from the list of fittings available to you from the associated piping specification. Typical fitting types are Elbows, Tees, Reducers, Flanges, Gaskets and Valves etc. There is some intelligence build into the PDMS forms so that by placing for example a valve the associated Gaskets and Flanges will also be created. For all piping components, you will need to carry out the following steps: - Select the component from the piping specification, position the component and set the orientation.


18

www.aveva.com

The tube is not created explicitly; it is created automatically and implied between adjacent fittings. 2.11 Creating Branch Components (Pipe Fittings)

The “Component Types” list shows the piping components that are available in the current piping specification, set at the Pipe and Branch level. Using the Select button, you could select components from an alternative specification if required. Components are created by selecting the required fitting from the list

2.12 Component Creation Form

The Component Creation form shows details of all the Sub-Types available in the piping specification. . For example a Flange may be Slip-on, Weld Neck, Screwed or Blind. You will be required to select the Sub-Type you require. Items are created in order with or against the flow of the pipe. A tick box is available to automatically create adjacent components. This is very useful for creating the flanges of in-line flanged components. For example, if a Valve is added the gaskets and flanges will also be added.


19

www.aveva.com

2.13 Component Selection Form From the Pipework Toolbar, select the Show pipe component selection form icon, the component Selection form is now displayed.

2.13.1 The components Tab

The Component Selection form can be used to change an existing component Sub Type or Spec. after it has been added, preserving its connections to adjoining components wherever possible. The selected component type will be displayed in the Type window, i.e. Flange etc.

From the available Sub-Types list select the SLIP ON FLANGE. The Component is changed and this can be seen in the graphical view

If the component has a different fitting-to-fitting length this can be reconnected using the Reconnection

Button. 2.13.2 The Specs. Tab The Specs. tab allows the user to select an alternative specification and set Insulation or Tracing.


20

www.aveva.com

2.13.3 The Errors Tab The Errors tab displays any errors which may result if an unsuccessful Reconnection operation is attempted.

2.13.4 The Options tab

Descriptions This option allows you to select the nature of the information shown for selected Components in the lists in the Components panel

The Descriptions of the component can be shown in Full, R Text, S Text, T Text or just as a Cat-Ref.

Tag component can be used to turn the Component marker on and off (on by default). Tag constraints can be used to turn on and off the highlighting of Components which could give bad connectivity if an adjacent Component is changed. Auto reconnect if selected, automates the function of the Reconnection button on the Components tab. Errors which may result if an unsuccessful Reconnection operation is attempted will automatically appear on the Errors panel Reconn. free ends if selected, re-establishes connectivity if the Pipe Head (or Tail) becomes disconnected as a result of Component reselection Ignore positioned if selected, ignores elements which have their RLOCK attribute set to 0. (RLOCK is the attribute for the branch members creation status code used by Router.) Selecting this option does not stop the model editor moving the Component, but by default the Component with RLOCK= 0 will not be moved when it is reconnected to the Component being changed


21

www.aveva.com

2.14 Branch Components List Order With equipment and structures, the order in which you create items is of no importance to the final outcome. With piping components, the order in which they are laid out, as well as their individual positions and orientations, determines the final pipe route.

To help with this a Component Position Pointer is displayed. Below is an example Design Explorer list showing the components of a branch /100-B-1/B1

As you can see by default there is no TUBE shown in the explorer window,

2.15 Typical Design Explorer showing Tube

Tube is shown by changing the Explorer setting Settings > Explorer Select Show TUBI/ROD

The example below shows the Explorer Window with the Tube Shown.


22

www.aveva.com

When using PDMS the list order will become second nature to you after you have created a number of branches, but for the time being you should be aware of it and should consider carefully where your next item is going to be inserted by watching the Component pointer and Design Explorer.

When you are creating a component at the pipe branch head or pipe branch tail you must ensure that you are positioned at the Branch.


23

www.aveva.com

2.16 Arrive and Leave Points Piping components have P–points (similar to those for equipment primitives). The significance of P–points is two–fold. First, they define the connection points, and second, they determine the branch flow through the component by means of Arrive and Leave attributes. For the reducer shown below, you will see that the large end is at P1 and the small end is at P2. If you use this component to increase the bore of the branch, the flow in the direction of the branch will be from P2 to P1. In order to tell PDMS the flow direction you want, you set two numeric attributes, Arrive and Leave, to the p–point numbers you want. In this case, Arrive would be set to 2 and Leave would be set to 1. (The default is Arrive 1 Leave 2). This is included for information, as the forms and menus will handle all connections.

2.17 Quick Pipe Routing

The Quick Pipe Routing Handle has three parts, Extend Route Handle – This is used to extend the route in the direction indicated by the handle. Cardinal Direction Handles - These are used to change the direction of the routing to one of the cardinal directions from the current frame of reference. Rotational Handles These allow the extended route handle to be interactively directed by the user. The quick pipe routing handle is used to define a routing vector within the constraints of the currently selected badly defined route. A badly defined route is defined in general terms as where either, there is a bad alignment between two components, the head or tail of a branch is incomplete, i.e. where the head/tail attributes are left in their default state, the head/tail is positioned but not connected and the head/tail connection type is unset. This usually equates to the dotted line representation of implied tube, where implied tube cannot be drawn. An exception to the above could be where a Pipe Branch does not have specification reference set. The handle can be dragged by using either primary or secondary mouse buttons. By default the handle will move in multiples of the currently defined linear increments. If the secondary mouse button is clicked as the cursor is over the pipe routing handle, the user will be presented with a context sensitive menu. The menu will display the available options which relate to the drag. 2.18 Extended Handle Pop-ups

The following options are available on the Extend Handle before a drag. Enter Offset This gives the Constrained Move form which allows you to enter an offset from the current handle’s position in the current routing direction.

Cardinal Direction Handles

Extend Route Handle

Rotational Handles

www.aveva.com

Enter Leg Length This gives the Leg Length form which lets you enter an absolute distance of the handle from the last previous change in the direction’s position. Distance From Origin This displays the Explicit Distance form which allows you to enter an absolute distance of the handle from the previous component’s origin position. Extend Through Feature This allows you to identify features with which to align, along the current route direction. Orient to Point This directs the handle either directly to a point feature or rotates about the vertical axis, maintaining horizontal offset, when a linear feature is identified. Align with Direction This allows you to identify features with which the handle is to be aligned. Explicit Direction This gives the Enter Direction for <direction> Axis form which lets you enter an explicit direction for the handle. Component Choice This allows you to select the type of Component that is created by the Routing Handle when a change in direction occurs. The Component can be set to either Elbows or Bends. Distance Feedback This allows you to select how the Routing Handle displays distance feedback. This can be set to either Offset (offset from the previous handle’s position), Leg Length (distance of the handle from the last previous change in direction’s position), or From Origin (distance of the handle from the previous Component’s origin position). Use the D 'hotkey' to cycle through the options. Show Rotation Handles This toggles the display of the Rotation Handles (selected by default). Cancel This returns the handle and selection to its original state before the drag The following option is only available when the end being routed to is ill-defined, i.e. there is no End Route Handle displayed: Connect To This enables you to select an element which the route end can be connected to, eg unconnected Nozzles, Tees etc. The following options are available on the Extend Handle on completion of a drag, i.e. when the secondary mouse button has been used to drag the handle and no special actions are active: Extend This leaves the handle at the shown position. Cancel This returns the handle and selection to its original state before the drag. The following options are available when in “snap to feature mode” and the end being routed to is ill-defined or unconnected and the identified feature is a connectable p-point of an item to which an end can be connected, e.g. a Nozzle with no connection reference set: Extend This leaves the handle at the shown position Connect This leaves the handle at the shown position and connects the ill-defined end to the identified target. Connect and Complete This establishes a connection to the identified item and completes the route and exits the route mode when applicable. Cancel This returns the handle back to its original state before the drag. The following options are available when in “snap to feature mode” and the end being routed to is well defined and the identified feature is the End Route Handle. Extend leaves the handle at the shown position Complete completes the route and exits the route mode when applicable. Cancel returns the handle back to its original state before the drag.

2.19 Rotational Handle Pop-ups

The following options are available on the Rotation Handle before a drag Enter Value This gives the Rotate Selection About form, enabling you to enter a value to rotate the graphical selection about the selected rotational axis Orient to Point This allows you to pick a p-line through a point with which to orient the Rotation Handle. Align with Direction This allows you to identify features with which the handle is to be aligned. Planes will be displayed to indicate a p-point direction (pointer symbol) or a p-line direction (symbol). Clicking and releasing the SHIFT key will reverse the direction of the handle. Align With This displays the Enter Direction For <direction> Axis form which allows you to align the handle with a specified direction, or as close as possible to the given direction, about the axis of the Branch. Rotate Handle Allows you to rotate the Locator Handle, using the same movement options as the main Rotation Handle menu. These options move the Locator Handle only, they do not move the Graphical Selection. Alternatively a 'freehand' movement of the Rotate Handle can be accomplished by clicking the H key with the handle selected and the left mouse button held down. The Locator Handle may be rotated independently of the Graphical Selection in order to change the frame of reference for the next operation on the Graphical Selection. Rotate Handle>To World This option aligns the Locator Handle with the World co-ordinate system,

without rotating the Graphical Selection. The Locator Handle Y axis points North, and the Z axis points Up.

Cancel This removes the shortcut menu and deselects the selected Locator Handle

2.20 Quick Pipe Routing (Example)

The tasks of setting up pipes, branches and components are simplified by the use of forms and menus. The main thing to remember when using the application is which specification you are currently using as a default. The course exercises and examples will illustrate different means of pipe routing by giving examples of many of the situations you will encounter. The quick pipe routing functionality will allow the user to correct the path of a pipe wherever there is an ill defined route within a branch, i.e. where the dotted line is displayed instead of implied tube. Highlight the dotted line, and select the Model Editor icon from the Model Editor Toolbar. The Pipe Component Modification handle will now appear at the component leave end. Enter the feature highlighting mode by clicking the F key on the keyboard or by selecting Selection > Feature Highlighting from the pull down menu Select the pipe component modification handle and press the right mouse button. From the pop-up select Component Choice > Use Bends. Holding down the left mouse button, drag the pipe modification handle across to the other end and still holding down the left mouse button, click the right mouse button. A second pop-up appears, select complete The bend and the implied tube are added to complete the route

The bend that has been added by the system can later be changed to a smaller radius bend or an elbow.

If the component choice had been Use Elbows, then this

would not have completed the route due the default elbow component is the first elbow component in the specification i.e. a 45 degree elbow

Selecting the Pipe component modification handle with the right hand mouse button will result in the implied tube been shown translucently

Position the valve and its connected components Fitting to Fitting with the second Elbow using the Model Editor.

Make sure you are NOT in Feature highlighting Mode using the F button whilst in Model Editor.

It is possible to move the valve assembly to other legs in the branch, these are indicated in blue.

You can connect the Flange to the elbow

You can also rotate the Valve in its axes.

Exercise 1 – Pipe Branch Worked Example Create pipe 100-B-8 and Pipe Branch 100-B-8/B1 as shown in worked example above.

Exercise 2 - Creating a Second Branch To complete the pipe create a second Branch that connects the tee to the second pump /P1501B, build up the Branch components as before. A new branch is created using the Show pipe modification form


43

www.aveva.com

Select the <New Branch> Button Connect the Branch Head to the Tee and the Pipe Tail to the Suction Nozzle of pump /P1501B

Remember you can connect Flanges, quick route elbows and then add the valve.

Make sure when creating your components you have set the Create Components Form to the correct Branch using the <Set Branch> button.

Exercise 3 - Building the Pipework Start to build up the Pipework on the plant. Refer to the drawings for positions and components required along each pipe. Remember to select the correct specification for each pipe. In general, the naming convention of the pipes is built up from pipe size, the third character of the specification (A3B) and a line number. Initially, create the following pipes: Pipe 80-B-7 When you create this pipe if the Nozzles are correct, i.e. both the same size and inline the tube will be implied and displayed. You should only need to create the flange connections, remember this is done by being positioned at the branch level in the Design Explorer.


44

www.aveva.com

Pipe 150-B-6 The Flanges and elbows at both the Head and Tail of this pipe should be created fitting to fitting. The elbows are rotated as required using Model Editor. This is quite a simple pipe so it could easily be routed using quick route mode.

The First elbow is rotated using Model Editor to face East.


45

www.aveva.com

Pipe 250-B-5

The Elbow can be lifted in-line with the next item in the branch using The Align selection / component Icon

Create and position a Tee as described earlier. Reducers are created in a similar way to Tees; make sure you select the correct Icon when selecting the bore.


46

www.aveva.com

Pipe 200-B-4

The bottom section of this pipe has a small offset of about 15 Deg. The two bottom elbows should be lined using Align selection / component as described earlier.

The Elbow can be directed to face towards the next elbow using the Direct selection / component Icon.

Navigate to the next Elbow and direct it in a similar way using the Direct selection / component Icon. 100-C-13 This pipe must be routed to piping spec F1C as it is stainless steel, the pipe head can be connected as we have done before. The pipe tail however must be created explicitly.


47

www.aveva.com

To set the Branch Tail, Select the Tail Detail Change button on the Create Pipe Branch form.

Set the details as shown on the form. Bore 100 Connection OPEN (The pipe will have an open end.) Direction W (as this is the opposite direction to the pipe route direction.) West 303000 North 308280 Up 104937 Select Apply

The pipe should be routed onto the Pipe Bridge. The steelwork for this pipe bridge is created using the macro !!traRunMacro('pipeway.pmlmac'). Navigate to a Structural Zone or create one /STRU.ZONE. Open a command line window using: Display > Command Line. Type !!trarunmacro('pipeway.pmlmac') into the command line and make sure it is typed in lower case. The steelwork will now be created. Create the Gasket, Flange and the first two elbows as described before. The third elbow is created and position with the Bottom of Pipe (BOP) onto the steelwork using the Quick Pipe Router.


48

www.aveva.com

Enter Model Editor with feature highlighting enabled (F). Select the dotted part of the pipe in Model Editor Mode. Make sure feature highlighting is enabled (F) Slide the mouse over the steelwork, when you are positioned over Top of Steel (TOS) pline, the extended route handle will be displayed. Select 1/2 OD behind Pline Feature, this will place the BLOB with BOP on TOS.

Continue the pipe in Quick Router Mode, the pipe can be finished using Auto Complete.


49

3.6 Copying Branches If you have branches of a pipe that contain similar components you may copy a complete branch then move it into position. To create a copy, select the branch to be copied then choose Create > Copy > Offset This will display the Copy form you will need to reconnect the branch head and tail and also rename the new branch. 150-A-57 This pipe should be routed using /A1A which is a 150# Carbon Steel specification. The second Branch will be copied as described later. Route Branch /150-A-57/B1 from the open Pipe Bridge to /P1502B/N1. The Pipe Tail of this pipe will be connected to the suction of pumps P1502A and P1502B, which has 300# Flanges. As there are no 300# flanges in our piping spec we are going to select them from spec /A3B this is done by setting The Alternative Spec. The Pipe Starts with an Open End on the Pipe Bridge.

Create the new pipe as described previously but the Branch Head is created using Modify branch head and specifying the position explicitly.

CHAPTER 5

5 Data Consistency Checker This Chapter shows you how to check the logical consistency of your design data, enabling you to find and correct the most common types of design error. You will normally carry out data consistency checks before you run the clash detection facilities. It is more convenient to do a data check on individual pipes than to do the whole Plant in one go. There may be too many errors to sort out at once.

5.1 Possible Types of Data Error The data consistency checking utility, available within Design’s Piping and Structural applications, checks the following aspects of your design (piping examples shown):

5.1.1 Angular Alignment Checks that components which are to be connected together are aligned in the same direction:

PL is E

PA is W30NN

5.1.2 Axial Alignment Checks that components which are to be connected together are aligned on a common axis:

offset axes N

5.1.3 Consistent Bores Checks that components which are to be connected together have consistent bores:

Leave Bore

50

Arrive Bore

100

5.1.4 Connection Types Checks that components which are to be connected together have compatible connection types:

Flange

connectionScrewed

connection

5.1.5 Minimum Tube Length Checks that no length of tube is less than a prescribed minimum (which may depend on its bore).

Component A Component B

Tube too short to allowfor practical assembly


66

www.aveva.com

5.2 Starting the Data Consistency Checks To carry out data consistency checking from within the Piping application, select Utilities>Data Consistency. You will see the following form:

By using this form, you can generate a diagnostic report on the data consistency of any part of your design. You may list the report on your screen (in the area in the lower half of the form), or you may send it to a file from which you can print a hard copy version. Select Screen or File and, in the latter case, specify the directory and filename. Choose the hierarchic level at which you want to check the design using the Check list near top left of the form. The default is the current element. Navigate to Pipe 100-B-8 Select Check Pipe and Apply 5.2.1 Specifying Parameters and Tolerances The data checking utility allows a margin of acceptable error before it diagnoses that you may have a problem. These built–in tolerances have default values, but you may set your own values if you prefer. Select the Piping Button

The above example shows the default settings for Angle, Offset, Ratio and Max. Angle.


67

www.aveva.com

5.2.2 Minimum Tube length As an example, by default your report will warn you of all lengths of tube in your design which are shorter than 100mm. This allows you to decide whether each such length is adequate for welding procedures, bolt withdrawal, access, and so on. You can change the acceptable minimum length from 100mm, and may set different minima for up to ten different pipe bore ranges if you wish. For example: A minimum length of 150mm for bores between 25 and 50. A minimum length of 300mm for bores between 50 and 100. To change any of the consistency check tolerances, use the appropriate Parameters button on the form (Piping for our current examples). And then select Tube Range. You will see a subsidiary form on which you can change any of the current tolerances before carrying out the data checks.

5.3 Data Consistency Check Report Format The report comprises a header, giving the date and time, followed by an itemised list of the elements being checked, together with numbered diagnostic messages describing any potential problems. For example: DATE 11 FEBRUARY 99 TIME 14.12 PIPE /PIPE2 BRAN /PIPE2/B1 B 10 TAIL REFERENCE NOT SET END If no problems are found, you will see the message: *** NO DATA INCONSISTENCIES ***

5.3.1 Data Consistency Diagnostic Messages You will find a full list of the data consistency diagnostic messages, each identified by a reference number, in the DESIGN Reference Manual. With experience, you will be able to identify which messages indicate errors which must be corrected, and which are merely warnings of potential problems. As an example, we will consider the design feature shown below, namely a Pipe to Pipe connection, and will look at some of the messages which might result.

The connection as shown is a valid one. If any of the connection types were changed, you might see the following messages: A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE

The connection types FBD-FBD in this example must be the same. B230 CONNECTION TYPE TCONN NOT SAME AS TERMINAL CONNECTION TYPE

The connection types GBD-GBD in this example must be the same. D430 BAD ARRIVE CONNECTION TYPE

The connection types GBD-FBD in this example must be listed as compatible in the COCO tables. E730 LEAVE CONNECTION TYPE (of the Flange) NOT COMPATIBLE WITH TCONN

The connection types FBD-GBD in this example must be listed as compatible in the COCO tables.

5.4 Some Examples of Data Consistency Diagnostic Messages The following examples explain the significance of some of the messages you might see during this training course: 5.4.1 Branch Head Errors The following diagnostics apply only to the Head of a Branch: A 10 HEAD REFERENCE NOT SET

The Head reference should only be unset (i.e. zero) if the Head Connection Type HCONN is set to OPEN, VENT, CLOS or DRAN.

A 20 HEAD REFERENCE POINTS TO NONEXISTENT ELEMENT

This error would result from the deletion of a component, such as a Nozzle, to which the Head of the Branch was originally connected.

A 30 BAD HEAD RETURN REFERENCE

The Head is connected to an element that does not refer back to the Branch. This can occur when the Head of a Branch is connected to another Branch, implying that a Tee should be placed somewhere along the second Branch. The error can also occur when two or more branches are inadvertently connected to the same terminal.

A200 DIRECTION HDIR NOT SAME AS TERMINAL DIRECTION

If the Head is connected to a terminal, such as a Nozzle or Tee, then the direction HDIR should always be identical to that of the appropriate p–point of the terminal.

A210 POSITION HPOS NOT SAME AS TERMINAL POSITION

If the Head is connected to a terminal, such as a Nozzle or Tee, then the position HPOS should always be identical to that of the appropriate p–point of the terminal.


69

www.aveva.com

A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE If the Head is connected to a terminal, such as a Nozzle or Tee, then the connection type HCONN should always be identical to that of the appropriate p–point of the terminal.

A300 REFERENCE HSTUBE UNSET

There is more than 1mm of tube between the Head and the p–arrive of the first Component (or the Tail), but HSTUBE is unset.

A310 REFERENCE HSTUBE REFERS TO A NONEXISTENT SPCOM

This may occur if part of the Specification has been deleted. A320 HSTUBE PROBLEM, CATREF IN SPCOM IS UNSET

This indicates an error in the Specification. A330 HSTUBE PROBLEM, CATREF IN THE SPCOM REFERS TO NONEXISTENT Catalogue COMPONENT

This may occur if part of the Catalogue has been deleted or if the CATREF is unset. A400 HBORE NOT SAME AS BORE OF HSTUBE

The bore of any tube leading from the Head, determined from the Catalogue, should always be identical to HBORE.

A410 HCON NOT COMPATIBLE WITH CONNECTION TYPE OF HSTUBE

The connection type of any tube leading from the Head, determined from the Catalogue, should be compatible with HCONN.

A420 ISPEC REFERENCE POINTS TO NONEXISTENT ELEMENT

This error would occur if, for example, the Insulation Specification pointed to by ISPEC had been deleted.

5.4.2 Branch Tail Errors The same type of errors may occur to the Tail of a Branch. The message numbers are the same as for the Head errors but are preceded by a B. B 10 TAIL REFERENCE NOT SET

The Tail reference should only be unset (i.e. zero) if the Tail connection type TCONN is set to OPEN, VENT, CLOS or DRAN.

5.4.3 Plain Branch Errors The following diagnostics can occur only for Branches with no piping components: C500 TUBE TOO SHORT BETWEEN HEAD AND TAIL

The distance between the Head position, HPOS, and the Tail position, TPOS, is greater than zero and less than the specified minimum tube length (default: 100mm).

C510 BAD HEAD TO TAIL GEOMETRY

Either the Head position, HPOS, does not lie at a positive distance along the line through TPOS in the direction TDIR or the Tail position, TPOS, does not lie at a positive distance along the line through HPOS in the direction HDIR.

The following illustration shows some typical examples:


70

www.aveva.com

C520 HBORE NOT SAME AS TBORE When there are no components on the branch, the Head bore, HBORE, should be identical to the Tail bore, TBORE.

C530 HCONN IS NOT COMPATIBLE WITH TCONN

This implies that the Head is connected directly to the Tail with no Tube or piping components in between; hence the Head connection type, HCONN, must be compatible with the Tail connection type, TCONN.

C540 THIS BRANCH HAS NO COMPONENTS

This does not necessarily indicate an error. It is output as a warning.

5.4.4 Component–Specific Diagnostics The following errors apply to individual piping components and, in some cases, to their adjacent connections. Some of the errors also apply to Nozzles.

5.4.4.1 All–Component Diagnostics These are applicable to any component, regardless of its position in the network: D100 REFERENCE SPREF UNSET

This probably means that you have forgotten to choose the piping component correctly. D300 CONN REFERENCE NOT SET

Multi–way Components may be left unconnected only if the connection type of the relevant p–point is OPEN, CLOS, VENT, DRAN or NULL.

D310 CONN REFERENCE POINTS TO NON–EXISTENT BRANCH

This may occur if the Branch which is pointed to by the CONN reference has been deleted. D320 BAD CONN RETURN REFERENCE

This may occur if the Branch which is pointed to by the CONN reference has been reconnected to another terminal.

D400 ARRIVE TUBE LESS THAN TUBE MINIMUM. ACTUAL TUBE LENGTH IS ...

The distance between the arrive p–point of this component and the leave p–point of the previous component (or Head) is greater than zero and less than the specified minimum tube length (default: 100mm).

D410 BAD ARRIVE GEOMETRY

The position and direction of the arrive p–point of this component are not correct with respect to the leave p–point of the previous component (or Head). The error could be caused by incorrect positioning of this component, the previous component (or Head) or both.


71

www.aveva.com

The following illustration shows some typical examples:

D420 BAD ARRIVE BORE

The bore of the arrive p–point of this component is not equal to the bore of the preceding tube or, if this component is not preceded by tube, to the bore of the leave p–point of the previous component (or HBORE).

D430 BAD ARRIVE CONNECTION TYPE

The connection type of the arrive p–point of this component is not compatible with the preceding tube or, if this component is not preceded by tube, to the connection type of the leave p–point of the previous component (or HCONN).

D500 REFERENCE LSTUBE UNSET

You have probably forgotten to select the piping Component. D600 LEAVE BORE NOT SAME AS BORE OF LSTUBE

The bore of the leave p–point of this Component is not the same as the bore of the tube following theComponent.

D610 LEAVE CONNECTION TYPE NOT COMPATIBLE WITH CONNECTION TYPE OF LSTUBE The connection type of the leave p–point of this Component is not compatible with the tube following the component.

5.4.5 End–Component Diagnostics These are applicable only to the last component in a Branch: E700 LEAVE TUBE LESS THAN TUBE MINIMUM. ACTUAL TUBE LENGTH IS ... The distance between the leave p–point of the current component and the tail position, TPOS, is greater than zero and less than the specified minimum tube length (default: 100mm). E710 BAD LEAVE GEOMETRY The position and direction of the leave p–point of this component are not correct with respect to the position, TPOS, and direction, TDIR, of the tail. The error could be caused by incorrect positioning of this component, the Tail, or both. E720 LEAVE BORE NOT SAME AS TBORE The bore of the leave p–point of this component is not the same as the tail bore, TBORE. E730 LEAVE CONNECTION TYPE NOT COMPATIBLE WITH TCONN The connection type of the leave p–point of this component is not compatible with the tail connection type TCONN.

CHAPTER 7

7 Hole Management On a typical AVEVA Plant project it is necessary for designers to create holes in panel elements, i.e. deck plates, grating, walls, floors, etc. Due to the implications on design integrity and cost, the hole creation process needs to be controlled and managed. The Piping Designer would not be able to create holes in floor plates or wall panels as these items would have been created by another design discipline for example the Structural Department. These design items would be held in another database for which the Piping Designer would only have read access. A method of requesting, approving or rejecting a hole between disciplines is required; this is known as Hole Management. The Piping Designer locates and sizes the hole and then makes a request for the hole to be created by the other discipline.

For the purposes of the training we will assume that we are both the Piping Designer and the Structural Approver so that the full workflow can be discussed.

7.1 Introduction to Hole Management

PDMS controls and manages holes using the Hole Management application which facilitates:

• Communication of hole data between disciplines including Request and Approval processes.

• Ensuring holes are only created by users with appropriate write access permissions.

• Performing validation checks on managed holes and providing feedback to users on the hole status.

• Generation of reports for managed holes.

Generally in AVEVA Plant projects discipline Designers do not have write access to items created by other disciplines, i.e. a Piping Designer does not have write access to Structural elements and Structural Designers do not have write access to Piping elements, etc. With Hole Management penetration holes are specified and requested by the penetrating discipline, normally piping, HVAC or equipment designers and approved by the penetrated discipline, normally structural Designers. For cases where a penetration is required, say, for a steel section through a deck/floor plate, the hole would be specified, requested and approved by the structural discipline. The specification of a penetration hole by the relevant discipline in the appropriate Design application creates a ‘virtual hole’ in the panel element, consisting of a FRMW and two FIXING elements. Each fixing element has a Specification Reference (Spref) attribute that points to the hole definition in the catalogue. An Association (ASSOC) element that references all of the hole elements is also created. Once the ‘virtual hole’ has been created the penetrating discipline enters the Hole Management application and requests the hole. The owner of the panel, normally the Structural discipline, then reviews and approves (or rejects) the hole request using the mechanism provided by the Hole Management application. The act of approving the request creates the ‘actual’ hole as a PFIT owned by the PANE element. The Hole Management application checks and validates the hole using the association restrictions and stores data on the hole history and status. Only valid holes may be approved. For a structural penetration the Structural Designer may be both the requester and approver, although specific company procedures, controlled by DAC, may be required if the Originator and Reviewer need to be different.


78

www.aveva.com

7.1.1 Hole Element Storage The ‘virtual hole’ FIXING elements are stored in a FRMW owned by a STRU whose Purpose attribute is set to HOLE, for example:

The STRU element is normally pre-defined by the System Administrator in the specific Design database. If a suitable STRU does not exist, the following error message is displayed:

The Hole Management associations are stored in an Association Group (ASSOGP) element owned by an Association World (ASSOWL) element. The ASSOGP must also have its Purpose attribute set to HOLE. The ASSOWL and ASSOGP elements are normally pre-defined by the System Administrator. An association is created for each hole and named on a simple sequential numbering system. Each association has several members of different element types that are not within the scope of this training guide. The Design Explorer may look like this:

If no ASSOGP element with the Purpose set to HOLE can be found, the Hole Management application will create an ASSOGP in the first writeable ASSOWL element and set the Purpose attribute. If no writeable ASSOWL element can be found the following error message is displayed. 7.1.2 Request and Approval Workflow Once the penetration hole has been specified and the ‘virtual’ hole created, the Hole Management application provides a series of tasks for the Originator (Penetrating discipline) and Reviewer (Structural discipline). These tasks are:

Originator Tasks Reviewer Tasks Request Approve Redundant Reject Cancel Request Agree Redundant Delete Entry

There are three main workflow scenarios for the request/approval cycle that are detailed in the following sections.


79

www.aveva.com

7.1.2.1 Hole Creation/Modification Workflow

In this workflow the Originator creates the ‘virtual’ hole and then either requests it or deletes the entry. Once requested, the Originator may cancel the request and delete the entry prior to it being reviewed. If rejected by the Originator If requested and not cancelled or deleted, the Reviewer checks the hole details and, if OK, approves the hole, thereby creating the ‘actual’ hole. If the Reviewer rejects the hole then the Originator can either modify the ‘virtual’ hole and re-request the hole or cancel the request and delete the entry. 7.1.2.2 Redundant Hole Workflow

In this workflow the ‘actual’ hole has been created. The Originator decides that the hole is now redundant and sets its status to Redundant. Before the Originator can delete the entry the Reviewer must agree that the hole is redundant.


80

www.aveva.com

7.1.2.3 Rejected Hole Workflow

In this workflow the ‘actual’ hole has been created. The Reviewer, possibly due to changed conditions, decides to reject the hole. The Originator has the option to: • Modify the hole and re-request it, whereby it will go through the normal review and approval cycle. • Cancel the request, in which case the ‘virtual’ hole details remain • Delete the entry, in which case the entire hole is deleted and the ‘virtual’ hole and association deleted.

The ‘actual’ hole is deleted and the panel restored to its original state. 7.1.3 Non-penetration Managed Holes In addition to penetration holes, the Hole Management application enables creation of non-penetration holes in structural panels. These holes fall into two general categories: • Holes that are required, say, for access to a piece of equipment, a valve or other design item. • Holes that are created by a panel fitting, e.g. a hatch, door, window, etc. For non-penetration managed holes that are not created by a fitting, with the exception of a User Defined hole type, the ‘virtual’ hole is created as a single FIXING in a new FRMW, as described for penetration holes. This fixing has a Specification Reference (Spref) attribute that points to the hole definition in the catalogue. An Association (ASSOC) element that references all of the hole elements is also created. Approving the hole creates an SFIT owned by the PANE. User Defined hole shapes are created using a template and negative extrusion in a similar way as described below for Fitting holes. For non-penetration holes that are created by a panel fitting, the ‘virtual’ hole is created as a single FIXING in a new FRMW. The fixing owns a Template (TMPL) element that owns a negative extrusion (NXTR) whose vertices describe the required hole shape. The fitting is created as a FIXING element owned by the PANE whose Spref attribute points into the catalogue to the selected fitting. An Association (ASSOC) element that references all of the hole elements is also created. Approving the hole creates an NXTR owned by the PANE that is a copy of the ‘virtual’ hole NXTR. Non-penetration managed holes, of either type, may be associated with any other element in Design. The holes have the same request/approval process as penetration holes, however, as they are created solely by the structural discipline the Structural Designer may be both the requester and approver.


81

www.aveva.com

7.1.4 Use of the Hole Management Application The Hole Management application, as with other applications that use associations, is passive, i.e. the user is not alerted if a hole association is broken or invalidated. The user must enter the Hole Management application and actively verify if the association is still valid. The use of the application will vary from company to company. In some it may be down to the individual Designers to request and approve holes, whilst in others it may be the discipline lead Designer or a designated user who performs the tasks. 7.2 Creating the Fixing Area The information about the hole size and position is held in a FIXIng which is held in a STRU with the purp of the STRU set to Hole, on a project this design area would be created by the project administrator. For the purposes of the training the fixing area will need to be created.

7.3 Creating single Pipe Penetration There are three ways that the Pipe penetration can be selected, shown on the pipe branch and subsequent isometric.

• Pipe Attachment (ATTA) selected from a special Penetration Spec.

This first method is very useful as the current piping spec does not need a special penetration attachment.

• Pipe Attachment (ATTA) selected from the current piping specification.

This method would allow the use of a different attachment representation on Isometric.

• Pipe Coupling (COUP) selected from the current piping specification.

This method is very useful if penetration material is needed on the piping isometrics. Typical uses of this are penetration sleeves or water tight seals.

In this first example a single penetration where pipe 100-B-8 goes through the floor plate /BOT-PANEL will be created with the piping attachment (ATTA) selected from the current piping spec.

Add Pipe /100-B-8 and Panel /BOT-PANEL to the screen.

Select Utilities > Pipe Penetrations > Create From the main window pull down

7.7 Requesting Holes Now the holes have been defined a request must be made for the holes to be created in the appropriate panel.

Navigate to the owner of both panels FRMW EROWC

Select Utilities > Hole Management from the main menu to display the Hole Association Management Form Check the Panel Checkbox to display the associations in the panels. Select Refresh Select both holes and Select Manage Selected Holes.

Under the Requester Tasks heading Select Request

Yes Expand the Hole validation results panel and check that all results are passed.

Expand the Hole History panel and note that the status has changed to REQUESTED


90

www.aveva.com

7.8 Approving Holes Remember the Piping Designer would not normally be able to approve the holes; Hole Approval is the

responsibility of the discipline that owns the Panel or Floor. Remove all items from the Graphics Screen

Select Utilities > Hole Management from the main menu to display the Hole Association Management Form Check the Panel Checkbox to display the associations in the panels. Select Both Holes Add to 3D view using the R.H. Mouse Button

Select the First Hole and Select Navigate to using the R.H. Mouse Button Select Manage Selected Holes.

Under the Reviewers Tasks Select Approve

The Hole will now be created.


91

www.aveva.com

7.9 Reject and Redundant Holes There may be many reasons why a hole can not be approved or required for example the position may not be suitable or the Pipe may have moved. The Hole Management Approval Manager allows cross discipline Approval, Rejection or redundancy of Holes.

Remember this is normally a cross discipline operation. Should it be considered that the Hole position is not suitable the hole request can be rejected.

In the example shown below the second hole has been rejected and the status of the Hole is set to Rejected.

If a hole is not required because for example the pipe has been rerouted then the Hole can be set as redundant. It can not simply be deleted because the plate may have already been cut so there is a mechanism in Hole management for Holes to be Redundant and for that to be agreed. In the following Example Hole two is Redundant.

Exercise 8 – Hole Management Using the above examples create holes to accommodate the pipes that pass through the floor plates.

CHAPTER 9

9 Sloping / Falling Pipelines All the previous pipework examples involved only orthogonal pipelines, that is, all lengths of tube were either horizontal or vertical. In practice, you often need to include lengths of tube, which slope at angles between components. This chapter describes how to position and manipulate sloping pipework..

9.1 Orientation and Positioning Components in Falling Pipelines PDMS 90Deg Elbows are capable of having a variable angle they are not fixed at 90deg. Variable angle elbows can be directed to the angle of the slope.

In the example below a tee has been added to the falling line to demonstrate how an offset error would be introduced. This error is corrected in PDMS using variable angle zero radius bends.

Bends are normally made from tube so adding a bend would only affect tube length and as the bend we use has no radius the effect is negligible; bends made from tube do not appear on the isometric material list. The following example shows how bends are used to correct falling lines. The diagram shows the tee still falling with the main branch; a bend is used at the start of the new branch to reduce the offset error.


96

www.aveva.com

In this next example the tee is horizontal and two bends are used one at each side to correct the fall.

You should always check contract procedure to establish how to design sloping pipes. The Auto Slope form allows the user to set the leave direction. This can be set to either up or down for each elbow in a branch. The slope can be specified either as a rate of fall or as an angle. 9.2 Creating Sloping Pipes Navigate to branch 1 of pipe /100-C-13. In the piping application select Modify > Slope…

Leave the fall to 1/100 Select OK


97

www.aveva.com

PDMS will now step through each elbow in the branch. You are required to select the slope for each elbow.

In each case select YES indicating the slope is up.

As the pipe is open ended finishing at the battery limit the following form is displayed.

As we wish the pipe end to remain in the same place we will select NO, the pipe tail will remain in the same position but the orientation will adjust to suit the sloping pipe. Should Yes be selected the Pipe Tail will

be repositioned at the leave of the last component. The pipe will now be sloping this can be checked using Query > General as we have done earlier. You should find the elbow direction to be of the form N 0.5729 U.

Exercise 10 - Creating Sloping Pipes Navigate to branch 1 of pipe /100-C-13 and modify the pipe slope as described above. 9.3 Controlling the Pipe Component Slope We are now going to add a tee, a new branch and a bend to correct the slope of pipe /100-C-13 that we have just made slope. Add a Tee to 500mm from the 3rd elbow. Use the RH Mouse Pull Down so you can set it 500 from the change in direction

As you will remember from previous discussion the P3 leave direction of the tee will not be directly up. New Branch Create a new branch and connect the pipe head to the tee, as in previous exercises the bore of the Pipe Branch Tail should be set 100mm but it can be left at the world origin for connection later.


98

www.aveva.com

The first item in this new branch must be a bend, Create a bend and select the Variable Angle (EV) and Radius bend in the choose form Set the Radius to Define and 0.00

Your branch should look like this.

We will now need to direct the bend up to remove the offset.

To direct the Bend up use Orientate > Component > Leave from the main top pull down.

Set the Direction to be U and tick the Change Angle Box.

Select Apply and Dismiss


99

www.aveva.com

Add an elbow and position it 1000mm from the Bend.

Use Orientate Component Slope to set the slope of the Elbow. Orientate>Component>Slope

Set the Slope to Up and apply the Form Set the Slope to Up

The PL of the elbow will now be sloping. The angle should be Direction N 0.5729 U.

Exercise 11 - Controlling Pipe Component Slope Create a tee, new branch and a bend to correct the slope as described above.

CHAPTER 10

10 Alternative Positioning Forms The following are some examples of positioning piping components in space and relative to other components. 10.1 Position>Component>Plane Through

The Plane Through form lets you position the current element using a specific co-ordinate, as in this example, or by using the cursor, or with respect to any other previously positioned item. 10.2 Positioning Piping Items Relative to Other Design Items You often need to position a piping component so that it, or its attached tube, is either just touching, or is a fixed distance from, another element in the design (another piping item, a structural beam or column, etc.). Until now we have always identified the position of a piping item by reference to its centreline (more strictly, its origin or P0). For relative positioning, it is often more convenient to use one of the extremities of the item as the reference, such as the top–of–pipe (ToP) or bottom–of–pipe (BoP), as we shall see in the following examples. 10.2.1 Position>Component>BoP/ToP (Infront)

Note: BoP/ToP in this context refer to the same point, namely the furthest side of the component. Thus,

the form settings Top of Pipe Clearance 50 Infront ID Cursor would achieve the same result. This applies in both forwards and backwards modes which are explained later.


102

www.aveva.com

10.2.2 Position>Component>BoP/Top (Behind)

Note: As in the preceding example, BoP/ToP here refer to the same point. Thus, the form settings Top of Pipe Clearance 50 Behind - D Cursor would achieve the same result.

10.3 Position>Component>BoP/Top - Non–orthogonal Pipelines For non–orthogonal pipelines, the following options are applicable: 10.3.1 Positioning Onto another Item

Position Bottom of Pipe Clearance 50 Onto ID Cursor

10.4 Positioning Under another Item For non–orthogonal pipelines, the following options are applicable:

Position Bottom of Pipe Clearance 50 Under ID Cursor


103

www.aveva.com

10.4.1 Positioning Infront another Item

10.4.2 Positioning Behind another Item

10.5 Position>Component>Clearance 10.5.1 Position>Component>Clearance (Infront)

Note: The form settings Clearance 50 Onto ID Cursor would achieve the same result in this example.


104

www.aveva.com

10.5.2 Position>Component>Clearance (Behind)

Note: The form settings Clearance 50 Under ID would achieve the same result in this example. 10.6 Position>Component>Clearance - Non–orthogonal Pipelines For non–orthogonal pipelines, the following options are applicable: 10.6.1 Positioning with Clearance Onto another Item

10.6.2 Positioning with Clearance Under another Item


105

www.aveva.com

10.6.3 Positioning with Clearance In-front another Item

10.6.4 Positioning with Clearance Behind another Item

10.7 Forwards and Backwards When using the above examples the designer is required to work with the flow in “Forwards” Mode or against the Flow in “Backwards” Mode. This can be changed on the command line using the command “FOR” or “BAC”. It can however be selected using the Piping Components Form. Select Create > Components

The Piping Components form should be used in conjunction with the Members form Select Display > Members


106

www.aveva.com

When you use the Forwards and Backwards Radio Buttons the Members window is inverted

Select Forwards

In Forwards Mode the first component in this example is a flange.

Select Backwards

In Backwards mode the first component in this example is a Valve.

Make sure you always close the form in Forwards Mode

10.8 Alternative Positioning Example Continuing from the elbow created in the previous exercise we are going to create two more elbows but this time we are going to position the elbows relative to the steelwork. Set-up the design display to include pipe /100-C-13 and the pipe bridge steelwork /PIPEWAY


107

www.aveva.com

Create a New Elbow and position it 300mm after the column Use Position > Component > Plane Clearance

Set the form as shown with a 300mm Clearance. Select Apply and Identify Column /COL-B3

Your elbow should be positioned as shown.

Direct the Elbow leave to point up using Orientate Component > Leave.


108

www.aveva.com

Another elbow is created and positioned so that the bottom of pipe is resting on the steelwork. Position > Component >BOP/TOP

Select Bottom of Pipe, Clearance 0, Behind, ID Cursor, Apply and Identify beam /AB4H

The Branch can be completed by specifying the tail as follows: Bore 100 Direction E Position W322000 N305440 U106457

Exercise 12 – Alternative Positioning Create and Position the Elbows relative to the steelwork as described above. Investigate using the Members window - Forwards and Backwards Mode.

CHAPTER 12

12 Pipe Splitting It is often necessary to split Pipes into more than one Branch or Pipe. Splitting Pipes is used to make the Isometric clearer or perhaps as a process requirement. Pipes can be split on components, on planes or into segments (or spools). Pipe assemblies are used to aid in the splitting of pipes. 12.1 Pipe Splitting at a component

Display Pipe /100-C-12 as shown We will split the Pipe at Elbow 3 of Branch /100-C-12/B1 The Pipe Splitting form is displayed using Utilities > Pipe Splitting

Select Split pipe by moving Component Select New Pipe Select Split

Identify Elbow 3

The Pipe will be split into two pipes, the upstream branch will keep the same name whilst the downstream branch will be given a new name /100-C-12-Split(1) The bypass should be included in this pipe

Navigate to Pipe /100-C-12-Split(1) Select Modify > Hierarchy > Include

The form will be opened on Pipe /100-C-12-Split(1) Locate the Bypass Bran /100-C-12/B2 Select Include CE

The Bypass branch will now be included in the pipe /100-C-12-Split(1) The Pipe and Branches should be renamed as required.

You should always run a Data Consistency Check if you edit a Pipe

12.2 Pipe Splitting on a Plane To aid with the following example Pipes /100-C-13, /100-C-12 and the pipe Bridge Steel /PIPEWAY have been added to the screen.

In the following example we will split both pipes using a pair of flanges 1500mm from the southern most pipe bridge column. The Pipe Splitting form is displayed using Utilities > Pipe Splitting

Note: The Split Pipe has been divided into sections for ease on explanation.

12.2.1 Elements to Split

There are 3 options for adding pipes to the Elements to Split which are self explanatory Add Pipe Branches /100-C12-B2 and /100-C-13-B1.

12.2.2 Split Pipe Options, (Split Pipe on Plane) There are various ways that the pipe split can be identified, in the example we will split the pipe on a plane. Other split options are described later.

The pipe will be split on a plane that we will define later. Select Split pipes on a plane

12.2.3 Moving Down Stream Components

There are three options following the pipe split: - Existing - Will just insert Pipe Assembly into the existing Branch New Pipe - The pipe will be split into new pipes New Branch - The pipe Branch will be split into extra branches. Select Existing 12.2.4 Plane definition

The plane is used to describe the position of the split, set the following: Plane Size 3000 Tick Fill Select Split Infront of the pick at a distance and a distance of 1500 Select Create plane

Pick any Pipe leg to place the cutting plane orthogonally Identify any of the pipes. Pick to position the cutting plane Pick the South West Pipe Bridge Column (F-1)


116

The Cutting Plane should be drawn as shown 12.2.5 Assembly Selection We will split the pipe using a pair of flanges

Select Sample assembly area Description FLAN GASK FLAN Assembly build origin Build to primary origin

12.2.6 Split Pipe To Split the pipes select the Split Button

Select Yes


117

The pipes should be split as shown below.

12.3 Split Pipe into Segments

This option can be used if you wish to split the pipe in for example 2000 lengths.

Select Split pipes into segments Split By Component picks

Select a Segment Length of 2000 As before Select a Weld Neck Pipe Assembly Select the Split Button

You will now be prompted to select the start and end of the leg to be split. Select Elbow 3 and Flange 2 of pipe branch /100-C13-B1

Exercise 17 - Pipe Splitting Using the above examples:

• Split Pipes /100-C-13, /100-C-12 on a plane

• Split Pipe /100-C-12 into segments Try splitting a Pipe into two pipes

CHAPTER 13

13 Pipe Editing (Component Bore/Specification) The modify Pipe / Branch components form can be used to change the Pipe, Insulation and Tracing Specs and also resize the piping components. It can be accessed from either Modify > Pipe > Component bore / Specification or Modify > Branch > Component bore / Specification. In the example we will change the Branch and Insulation Spec and resize some components. Navigate to and display pipe /250-B-5

13.1 Changing Component Spec

Select Modify > Pipe > Component bore / Specification

Using the Right Hand Mouse Button on the display window displays the Modification Pull Down

Use the Right Hand Mouse and Select All


120

www.aveva.com

In this case we do not wish to change the pipe spec on the Flanges and Gaskets as they are connected to 300# Nozzles Identify all Gaskets and Flanges using the L.H. Mouse Button with the <Ctrl> Key held down this will de-select the Flanges and Gaskets leaving the rest selected.

The Selection is also shown in the Graphics Window

Use the Right Hand Mouse and Select Modify Specification


121

www.aveva.com

The current Piping Spec will be displayed, Select Spec A1A using the pull down and OK

The right hand end of the form displays details of the component specification reference and description changes. These should be reviewed prior to using the Apply Button. In our case there are no errors but typical errors are shown below.

Any errors should be reviewed using the Error Message Tab as you can see in the above example the Tee shows a comment “No selection available” Select the Error Messages Tab


122

www.aveva.com

The spec that the Branch has been changed to does not contain a 250NB Butt Weld Tee, this will need to be resolved manually and could involve selecting a different component type. Select Apply to make the changes

Exercise 18 - Pipe Editing (Component Bore/Specification) Using the above example change the piping specification from /A3B-TRA to /A1A-TRA on the piping components, make sure that the Flanges and Gaskets are not changed. Run a Data Consistency check on the modified Pipe. In a similar way change the insulation spec to W

The Branch Temperature will also need to be set to 150 Deg using Modify > Attributes at Branch and Pipe Level. In order to see the insulation you will need to show the insulation using Settings > Graphics Representation and setting the Insulation to 25%


123

13.2 Changing Component Nominal Bore The modify Pipe / Branch components form can be used to resize the piping components. It can be accessed from either Modify > Pipe > Component bore / Specification or Modify > Branch > Component bore / Specification. In the example we will resize some components. Navigate to and display pipe /250-B-5

Select the two elbows and the reducer using the Cursor Select Modify > Branch > Component bore / Specification

Use the Select from graphics button to select the components for change. Using the Right Hand Mouse button Select Modify Bore


124

www.aveva.com

Change the bore to 150mm and OK

You can see that there is no available reducer so it will not be changed Select Apply


125
