What I Need to Know

Have you heard the saying, “A picture is worth a thousand words”? This

phrase is true specifically about technical drawings.

An engineer, a designer or an architect uses drawings to be able to describe

the size, shape, and relationship of a compound object. Hence, drawings have

become the universal language to communicate the necessary information for the

construction, assembly and service of industrial products.

In this module, you will learn independently on how to read the plumbing

layout plan. This includes the different types of lines; plumbing or piping drawings;

plumbing signs, symbols, and plumbing fixtures.

The lesson comes with learning activities designed to measure your progress.

You have to answer each to the best of your ability and be honest as you can.

Hopefully, after learning this module, you will be equipped with knowledge and

skills in Preparing Pipes, Tools and Equipment for Installation in Plumbing.

At the end of this module, you should be able to:

Lay out work area for pipes installation. (TLE_IAPB9-12PI-Ia-b-1)

Read plans and details in accordance with job requirement.

READ PLANS AND DETAILS

IN ACCORDANCE WITH JOB

REQUIREMENT

What’s In

Have you tried giving a direction of a place just by writing it in a sentence? It

is difficult, right? It can be easier if you draw the direction of the place. Just like in

plumbing, a plumber can easily locate the different plumbing needed to be installed

if it is in a drawing or layout plan.

In this module, you will be learning on how to read the plumbing layout

plan. This includes the different types of lines used in drafting plumbing or piping

drawings.

Are you excited for this lesson? You may now proceed with the next activity.

10

What’s New

At this point, you are heading into meaningful activities and learning

encounters. Complete the exercises and answer the learning activities to experience

lifelong and practical learning that awaits at the end of this module.

Activity 1.2 Identify Me!

Directions: Identify the various line types used in the drawings. Choose your

answer from the words inside the box and write it on the space

provided.

11

What is It

Reading plans and details in accordance with job requirement is a

challenging task. That’s why in this part of the module you need to read each item

carefully and try to master the uses of each term for this will be your guide in doing

your next activities.

DEFINITION OF TERMS

Analyze is to examine something in great detail in order to understand it better.

Blueprint is a photographic print of technical drawing with white lines and blue

backgrounds.

Dimension is the measurement of one or more direction such as length, width, and

height.

Interpret is to ascribe particular meaning of significance to something.

Pictorial Diagram shows the basic form or lay-out of pictures of actual component.

Plan is a method of doing something that is work out in advance.

Schematic Diagram shows the basic form or lay-out of plumbing symbols.

Sign is something that indicates the rule to follow.

Symbol is something that represents abstraction with the names of plumbing

components.

Line can be described as a straight one-dimensional figure, without thickness and

endlessly extending in both directions.

READING PLUMBING LAYOUT PLAN OR PLUMBING DRAWING

The first step in reading a plumbing drawing is to learn the meaning of each line.

Lines are part of the information needed to fully understand the drawing. These

lines are commonly referred to as Alphabets of Lines.

USES OF ALPHABETS OF LINES

1. Object Line

A visible line, or object line is a thick line used to trace the edges or contours of

an object.

12

2. Hidden Line

A hidden line, also known as a hidden object line is a medium weight line used

to show edges, surfaces and corners of an object which cannot be seen.

3. Section Line

Section lines are thin lines used to display a section view of the cut surfaces of an

object.

4. Center Line

Center lines are very thin (size) line made of long-short-long lines. It is used to

indicate the centers of holes, arcs, and symmetrical objects.

13

5. Dimension Line

Dimension lines are thin lines used to show the size of an object. Both ends of the

dimension line have arrowheads stopping at the extension lines.

6. Extension Line

Extension lines, a thin line which shows the boundary of dimension line. An

arrowhead of the dimension line touches the extension lines.

14

7. Leader Line

Leader Line is much thinner line used to point to a drawing area that requires an

explanatory note. Preferably they’re drawn at 45° angle.

8. Cutting Plane Line

A cutting plane line is a thick line use to illustrate the internal shape at a part or

assembly by cutting through the object.

9. Break Line

15

Break Lines are used to shorten the view of a long part of an object.

Short and long break lines are used for flat surfaces. Cylindrical are used on rods,

dowels, etc.

10. Phantom Line

Phantom lines are long-short-short-long lines used to display the movement of an

object or part in opposite positions. It can also be used to view adjacent objects or

features.

Aside from the different kinds of lines, a plumber must also be familiar with the

different plumbing or piping drawings. To read a drawing correctly, a plumber

needs to have a clear understanding of the various types of drawing and its

projection.

16

PIPING DRAWINGS

Piping drawings illustrate the location and size of pipes, fittings, and valves. There

are two projection methods used in pipe drawings. These are orthographic and

isometric (pictorial) pipe drawing.

ORTHOGRAPHIC PIPE DRAWINGS

Orthographic drawings are single-angled projections. Objects can be illustrated in

the front view, the side view, and the top or plan view.

Figure 1 - Orthographic projection of a toilet.

Figure 2 - Orthographic projection of PVC Tee

In a single pipe illustration, it is recommended to use Single- and double-line

orthographic pipe drawings. This method may also be applied to more complicated

piping systems.

17

Figure 3- Single-line orthographic pipe drawing.

Figure 4 - Double-line orthographic pipe drawing of fig. 3.

ISOMETRIC (PICTORIAL) PIPE DRAWINGS

Isometrics display a three-dimensional object in a single image, from three

viewpoints. The finished drawing, in pictorial format, is easier to understand.

Single-line drawings show all essential information to layout and produce a

piping system. Double-line pipe drawings are not recommended for production

drawings because it requires more time to draw.

18

Figure 5—Single-line pictorial piping drawing

Figure 6 - Double-line pictorial piping drawing.

CROSSINGS

Crossing of pipes are used when there is a need to show a certain pipe is behind

another, the line representing the pipe farthest from the viewer will be shown with

a break, or interruption, where the other pipe passes in front of it.

19

Figure 7-A—Crossing of pipes.

Crossing of pipe shown without interrupting the pipe passing behind the nearest

pipe.

Figure 7- B—Crossing of pipes.

Using an interrupted line to indicate pipe furthest away.

What’s More
