DUCTILE IRON PROPERTIES Ductile iron is an iron/carbon/silicon alloy. In 1948 it was discovered that with the addition of magnesium to the molten iron, the graphite forms in spheres rather than flakes.

HISTORYHAM BAKER is a name most professionals in the water andwastewater industries will instinctively associate with high qualityprecision-engineered products. Established over 100 years ago theoriginal company has undergone many changes over the lastcentury and more recently changes of ownership.
The company is acknowledged as a world leader in the design andmanufacture of fluid control products, and products manufacturedby the company can be found operating in almost every country inthe world.
ROBAN DUCTILE WELDING LTD was formed more recently in1974 as a distributor of pipeline fittings. Over a period of 25 years,the company grew, through innovation and investment inmanufacturing facilities both in the UK and overseas, to becomethe second largest manufacturer of ductile iron pipes and fittings inthe UK. Roban is the market leader in the supply of pipelineproducts to the M&E and pump equipment markets.
In 2001, Roban was acquired by the WTB Group of Bristol andfollowing the subsequent acquisition of Ham Baker in 2002 the twocompanies merged to form HAM BAKER ROBAN.
Following a second merger in 2004 with OLYMPIC PIPELINES thecompany, now HAM BAKER LTD. was restructured into twodivisions, Pipelines and Flow Control, to reflect the two distinctareas of expertise within the company.
HAM BAKER FLOW CONTROL produces the Hartley range ofductile iron and stainless steel penstocks, flap valves and stoplogs, and other flow control equipment.
HAM BAKER PIPELINES produces the Roban range of ductileiron pipes and fittings, steel pipes and fittings, valves, couplingsand ancillary fittings.

3.4 No deviation in the standardised length is permitted for fittingssupplied to series B.
3.5 Tolerances on lengths of socketed and flanged fittings aregiven below and are in accordance with BS EN 545 Section 4.2.3.4 Table 6.
4.WALL THICKNESS
4.1 The thickness shall be calculated either by the K class formula,as detailed in BS EN 545 Section 4.2.1.2 for potable water, orin BS EN 598 Section 6.1.3 for sewage.
e = K (0.5 + 0.001 DN)e is the nominal wall thickness in millimetres;DN is the nominal size;K is a coefficient used for the determination of the thickness.These are expressed by a series of whole numbers e.g. 7, 8, 9, 10, 11, 12, 14....
4.2 The minimum thickness classes for pipes and fittings are given in the following tables.
4.3 The tolerances on nominal wall thickness of pipes and fittings are detailed in BS EN 545 Section 6.1.1.
5. EXTERNAL DIAMETER
5.1 The specified diameter (De) of the spigot ends of pipes arespecified in BS EN 545 Section 4.2.2.1 and BS EN 598 Section 4.2.1.1. These figures are given in the table on page 13.
5.2 For DN ≤ 300, the external diameter of the pipe barrel measured with a circumferential tape shall be such as to allowthe assembly of the joint over at least two thirds of the pipelength from the spigot end. For DN > 300, the same applies toa percentage of the pipes, when they need to be cut on site,after agreement between manufacturer and purchaser.
5.3 The ovality of the spigot end of pipes and fittings shall:– remain within the tolerances on De for DN 100 to DN 200;– not exceed 1% for DN 250 to DN 600 or 2% for DN > 600
Note: The manufacturer’s guidance should be followed as to thenecessity and means of ovality correction; certain types of flexiblejoints can accept the maximum ovality without a need for spigotre-rounding prior to jointing.
6. PRESSURE TEST - FITTINGS
6.1 Allowable test pressure (PEA). All Ham Baker Pipelines’ fittings receive a 100% maximum hydrostatic pressure test.
6.2 The table given below details the maximum values foroperating and testing pressures.
1PFA - allowable operating pressure.Internal pressure, exclusive of surge, that a component can safely withstand.
2PMA - allowable maximum operating pressure.Maximum internal pressure, including surge that a component can safely withstand in service.
3PEA - allowable test pressure.Maximum hydrostatic pressure test that a newly installed component can withstand for ashort duration. Please note that component test pressure is different from a system testpressure, which is related to the design pressure of the pipeline.
7. JOINT PERFORMANCE
7.1 Socket spigot joints are designed to be fully flexible and allow angular deflection, which permits the installed pipeline to accommodate ground movement. The following table showsthe maximum allowable deflection of the socket:

3.3 The permissible deviations on the standardised length of seriesA fittings are given below and are in accordance with BS EN545 Section 4.2.3.3 Table 5.
To meet the requirements for potable water in the United Kingdomand comply with DWI Regulation 31, the standard corrosionprotection systems offered are:
PIPES Internal Lining: Pipes are lined with sulphate resistant cement and then sealed withan epoxy resin over the cement. The lining has full Drinking WaterInspectorate (DWI) Regulation 31.4(a) approval.
Alternatively, for flanged pipework, in applications such aspumping stations, treatment works and valve chambers the pipesare supplied as standard with sulphate resisting cement to BSEN 545 Section 4.4.1. and 4.4.3. The lining complies with DWIRegulation 31.4(b).
Cement Mortar LiningsThe cement mortar lining (CML) of ductile iron pipes ismanufactured to BS EN 545 Section 4.4.3. The lining shallconstitute a dense, homogeneous layer which covers the internalsurface of the pipe. The compressive strength of the CML aftercuring shall be not less than 50MPa. The surface of the CML shallcomply fully with BS EN 545 Section 4.4.3.3. The lining shall besmooth and uniform. Trowel marks, protrusion of sand grains andsurface texture are acceptable. Fine crazing and hairline cracksmay appear in dry linings.
The following table details the minimum thickness in millimetres ofthe lining of ductile iron pipes and fittings.
NOTE 1Cement Mortar Linings at pipe ends may chamfer to a maximum of 20mm.
NOTE 2Storage of pipes in a hot, dry environment can cause the pipe to expand and the mortar toshrink. This may result in the dry lining developing area’s of disbondment and shrinkagecracks which could exceed the widths given in the table above. Upon the lining being re-exposed to water, the lining will absorb the moisture and the crack will close. This is knownas an autogenous healing process.
NOTE 3
A negative tolerance only is given.
External Coatings: The pipes are supplied with a layer of metallic zinc to BS EN 545Section 4.4.2.1. and finished with a layer of Black Bitumen or blueepoxy to BS EN 545 Section 4.5.2. The metallic zinc is applied witha minimum mass of 200g/m2.
FITTINGSInternal and External Coating with Blue PPA 571 Plascoat:Ham Baker fittings are supplied coated with blue PPA 571Plascoat 250 microns (mean.) as standard, complying to BS EN 545Section 4.1.4. and Section 4.5. Plascoat has full BS 6920 approval.Alternatively, the fittings can be coated with Blue Resicoat 250microns (mean).
Fittings coated with either Plascoat or Resicoat having a coatingthickness of 250 microns may be buried in soils of all levels ofcorrosivity (non to highly aggressive).We can also offer fittings with a cement mortar lined (CML) finishinternally and a bitumen coating externally.
APPROVALSPipes: The pipe linings have full DWI Regulation 31.4(a) approvaland are listed in the Water Regulatory Advisory Scheme (WRAS)‘Water Fittings and Materials Directory’.
Fittings: The coating of our fittings for potable water is approved toBS6920, which means that the fittings comply fully with therequirements of DWI Regulation 31.4(B). Ham Baker Pipelines’ fittingsare listed in the WRAS “Water Fittings and Materials Directory”.
Ductile iron pipes and fittings finished with the coatings detailedmay be used to convey all types of water for human consumption.

28. STRUCTURAL STRENGTH
8.1 To demonstrate the strength and leak tightness of fabricated (welded on) flanged pipe, Ham Baker Pipelines subject pipes toa type test as detailed in BS EN 545 Section 5.4.
8.2 A fundamental requirement of flanged pipework is its ability to support an external bending moment. The length of anunsupported span is limited by the need to confine stresses dueto the combined effects of internal pressure, bolt tightening andbending moments within safe limits. These same limits alsoapply to flanged pipework subjected to loads caused by thrustsdue to internal pressure, e.g. at changes in direction.
The limits are such that it is recommended that flanged pipe isNOT buried.
Ductile Iron Fitting Production Process and Quality Control
The diagram below details the manufacturing process for HamBaker Pipelines’ ductile iron fittings with particular reference toquality assurance to ensure consistency of quality.
HYDRAULIC FLOW CHARACTERISTICSThe advance in corrosion protective systems, such as the use ofepoxy coatings, adds greatly to both its service life and its alreadyimpressive flow characteristics.
For specific details of flow capacities and velocities contact ourTechnical Sales Department.
LINING REPAIRIn the event that an area of cement mortar lining is damaged,repairs can be made quickly and simply by using either cementmortar or a compatible synthetic material which is approved foruse with the potable water. Where a repair is carried out usingcement mortar follow the procedure outlined below.
The cement mortar must be of the same type as that used inthe original lining.
• If possible position the pipe or fitting with the damaged area at invert level.
• Carefully chip out the damaged lining. Undercut the edges of the adjacent sound lining to help form a ‘key’ for the repair.
• Clean away all loose debris.
• Thoroughly wet the exposed metal surface and the edges of the lining around the exposed area.
• Prepare the mortar for the repair.
This should be stiff and consist of one part cement to approx. 1.5 parts of dry washed coarse sand (by mass), and be mixed with fresh potable water.
• Place the mortar with a hand trowel (or float for large areas), and work it well into the edges of the existing lining.
• Build up the repair to a thickness just above that of the original lining and finally smooth down to the required thickness using a piece of wood against the pipe end, if appropriate, to produce a square end. Cover with a wet sack, or similar, to prevent rapid evaporation until mortar is sufficiently hardened.
1. Note
If using synthetic materials follow the manufacturer’s instructions.
2. Note
For pipes having an epoxy seal coat, it is only necessary to repair damage to the cement. No attempt should be made to repair the seal coat itself.
NOTE:
Other coatings and linings are available to special order. Pleaseconsult our Technical Sales Department.
SEWAGE
All Ham Baker Pipelines’ ductile iron pipes and fittings for sewageapplications are supplied as detailed below:
PIPES
Internal Lining: Spun pipes will be lined with High Alumina cement in accordancewith BS EN 598 Section 4.4.3.
External Coatings:The pipes are supplied with a layer of metallic zinc to EN 598Section 4.4.2. and have a finish layer of Red Epoxy as per EN 598Section 4.1.4. and 4.4.2.4.
FITTINGS
Internal and External Coating: Fittings will be supplied with a red Plascoat finish as standard inaccordance with BS EN 598 Section 4.5.2.
pH LevelsOur standard coating systems are suitable for pH levels between 4and 12. For pipelines which have a process medium with pH levelsless than 4 or greater than 12, please consult our Technical SalesDepartment. For the chemical resistance of our pipes and fittingscontact our Technical Sales Department.
CEMENT MORTAR LININGS
The surface of the lining will be substantially smooth; trowelmarks and protrusions of sand grains are acceptable, but mayoccasionally contain longitudinal and circumferential shrinkagecracks but these will not affect the stability of the lining and thewidths of the cracks and any radial displacement at the crackswill not exceed the values given in the table below.(Dimensionsin millimetres)
NOTE 1Pipe ends may have a chamfer of maximum length 20mm.
NOTE 2Storage of pipes and fittings in a hot, dry environment can cause metal expansion andmortar shrinkage which may result in dry lining developing areas of disbondment andshrinkage cracks. When the lining is re-exposed to water, it will swell by absorption ofmoisture and the cracks will eventually heal by an autogenous process.
NOTE 3A negative tolerance only is given.
HIGH ALUMINA CEMENT RESISTANCEAbrasion Resistance: Abrasion in fluid transmission can result when the conveyed liquidcontains a high concentration of solids. High velocities will alsoincrease the abrasion of the pipe wall. This abrasive effect canerode the pipe wall over a period of time. It is likely to be aproblem in the following situations:
• Combined sewers
• Industrial effluent
• Steep slopes
The high alumina lining used by Ham Baker Pipelines offers excellentresistance to abrasion. This lining allows regular maximum flows upto 7m/sec with minimal attack in each of the above situations.
Resistance to septic attack: Bacterial corrosion is one of the main causes of deterioration ofsewage networks regardless of climatic conditions. Normallyassociated with hot climates such as the Middle East andAustralia, bacterial corrosion can occur in temperate climatesunder the right conditions – periods of low flow, turbulence at apumping main discharge point.
Hydrogen sulfide (H2S) released by the effluents is transformed intosulphuric acid by the bacterial micro-flora on the damp walls of thepipes. Tests have demonstrated that high alumina cement is a materialwhich offers high durability in the presence of bacterial corrosion.
Resistance to chemical attack: Sewage networks can be at risk from attack by chemicals found inindustrial effluents. The following table taken from BS EN 545Annexe E shows the resistance of high alumina cement comparedwith Portland cement.

Project IdentificationHam Baker Pipelines can mark all pipes and fittings toyour specific requirements. This can be done either bythe use of metal tags or white water resistant markers.
Flanged pressure pipelines are suitable for a wide range ofindustries and applications, primarily, pumping stations, treatmentworks, process plant and rising mains.
Rigid and self anchoring, flanged joints give no provision fordeflection, and therefore no external anchorage is required whenchanges in direction occur, or at blank ends. To give the flexibilitywhen installing a flanged pipeline system, the use of flangeadaptors is common practice.
The flanged joint offers a high strength and high pressurecapability, making a ductile iron pressure pipeline an ideal costeffective material when used in the movement of sewage andwater in above ground applications.
It is recommended that flanged pipework is not used in buriedsituations due to the risk of excessive bending moments.
However, where flanges are buried directly in the ground, (i.e. flangeadaptors), the bolts must be protected from corrosion by wrappingwith a protective tape or coating to WIS 4-52-03. Flanged joints areusually used for connecting valves, pumps and hydrants.
FIXED FLANGED JOINTS
ROTATING FLANGE JOINTS
In addition to our range of fixed flanged fittings, we can offer arange of fittings with an adjustable rotating flange as perBS EN 545 (Section 3.5) and BS EN 1092-2 (Section 3.1).

PUSH FIT JOINTS
The Push Fit socket is the standard joint for below ground waterand sewage pipelines. This is a high performance joint suited fordistribution mains.
Quick and easy to install, requiring no special back fill, Push Fit iscapable of angular deflection and longitude withdrawal withoutloss of performance. Other advantages are, high strength forassured security, able to operate at 60 bar pressure (depending onnominal bore).
All pressure pipelines with socket and spigot push fit flexible jointare subject to forces which tend to separate the joints, particularlyat changes in direction or at blank ends. At such points some formof restraint is required. The use of concrete thrust blocks iscommon practice. Where possible, concrete thrust blocks shouldbe shaped to allow sufficient space for remaking of joints.
To eliminate the need for thrust blocks, anchor gaskets and/or tiebar pipes can be supplied, where the ground is unstable or subjectto subsidence, where steep inclines are to be negotiated or wherethe pipes are to be laid above ground or under rivers and lakes.
SPECIFICATIONS
• A deflection of 1º on a full length of socket pipe (standardlength 6m) will provide a deflection of approximately 100mm from the axis of the pipe or fitting previously installed.

The flange convertor is the perfect engineering solution forconverting imperial flanges to metric flanges within a confinedenvironment such as refurbishing a pumping station.
The 3” and 4” are manufactured to Ham Baker Pipelines’ owndesign, this unique flange convertor covers - 3 inch imperial to80mm metric, and 4 inch imperial to 100mm metric as standard. Thebody is cast in ductile iron and coated in blue Plascoat as standard.
Bright zinc plated bolts are inserted from the back of the flangeinto the recesses which accept the head and prevent rotation,finally full faced EPDM gaskets are fitted to both sides before thewashers and nuts are applied.
Flange convertors are supplied completely assembled ready for use.
All other sizes are supplied with steel bodies with studs set into therequired position.
Larger flange convertors are available upon request.
FLANGED JOINTING MATERIAL
BOLTSFor convenience all bolt sets are supplied in polypropylene bags.Each bag contains the correct amount of bolts, nuts and washersto effect a flange joint , and is ordered by nominal bore size andpressure rating.
All materials comply with the requirements of the relevantBritish Standards.
Metric black hexagon bolts - BS EN ISO 4016 : 2001Metric black hexagon nuts - BS EN ISO 4034 : 2001
Metal washers for general engineering purposes - Metric series - BS EN ISO 7091 : 2000
Hot dipped galvanised coating grade 4.6 to BS EN 1461 : 1991
In addition to galvanised, Ham Baker Pipelines can supply boltsets with any other coating on request, including ‘Sheraplex orRilsan Nylon II’ which conform to WIS 4-52-03.
Stocks of standard length bolt sets are kept for DN 80mm - 800mm.
Non-standard bolt lengths, studs or tie rods in any material andfinish can also be supplied upon request.
Care should be taken when doing joint set take-offs, to ensure thatadequate attention is paid to the jointing of dissimilar products andmaterials, as this affects the length of bolt required.
FLANGED GASKETS
All flange gaskets supplied are manufactured from Water Councilapproved Ethylene Propylene Di Methyl rubber to BS EN 681-1.
All materials in contact with potable water have been tested to establish that they comply with the requirements of BS 6920.
Ham Baker can offer three different types of gasket as shown in sizes DN80 - DN800.
JOINT SET
Each standard joint set consists of the required number of mildsteel galvanised bolts, nuts and the washers per bolt, along withan IBC, EPDM flange gasket.
For buried applications, joint sets can be supplied with ‘Sheraplexor Rilsan Nylon II’ coated bolts which comply with WIS 4-52-03. Inaddition bolts can be supplied in grade 1.4401 (A4) or 1.4301 (A2)stainless steel.
Other gasket types and materials can be supplied upon request.

DRILLED AND TAPPED SOCKETS
Drilled and tapped sockets can be positioned almost anywhere, onany type of ductile iron pipe DN 80 to DN800.
Socket sizes range from 1⁄8” BSP to 2” BSP.
DRILLED AND TAPPED BOSSES
Drilled and tapped bosses with a maximum outside diameter of75mm can be applied to any type of ductile iron pipe and fitting,when a more substantial mount is required.
Welded bosses can be supplied plain for drilling and tapping on site.
Standard boss outside diameters are 25mm, 50mm and 75mm.These can be drilled and tapped 1⁄8” BSP through to 2” BSP.
Note: Sockets and bosses will always be positioned at 90º to thecentre line of a pipe or fitting as standard. Should any otherlocation be required, a sketch or drawing must be supplied.

BOLT TIGHTENING SEQUENCEBolts should be tightened in the correctsequence and a sufficient number ofcircuits undertaken to ensure that thespecified bolt torques are achieved. It mustbe noted that on flanged joints usingelastomeric gaskets some compression setof the gasket will be experienced and itshould be ascertained that the boltingtorques required to effect a seal at theappropriate pressure, as shown in thetables, are effective at the time of pressuretesting. Bolt torques do not have to berestricted to those applicable for a specifictest pressure and higher torques can beapplied up to the maximum rated testpressure of the appropriate flange.
• Use 3mm thick 70 IRHD BS EN 681-1 rubber gaskets, to suit flange drilling
• Clean flange faces, position gasket
• Use undamaged rust free joint sets
• Lubricate bolt threads and all mating surfaces and flanges
• Use automotive grade of oil/grease
• Tighten bolts in the sequence, as shown
• If necessary, re-tighten bolts BEFORE pressure testing
For pipes and fittings over 150mm nominal bore, it is recommendedthat two fitters working simultaneously on diametrically opposedbolts tightening first nut in first quadrant then first nut in secondquadrant returning to the second nut in first quadrant and so on.
It is important that a sufficient number of circuits are carried out toachieve the specified torque on every bolt.
ROTATING FLANGES
Rotating flanges allow easy assembly of flanged equipment in thenetwork independent of the flange position. Moreover, it is possibleto modify the flange drilling i.e. B.S.10, without having to changethe entire fitting but only the flanges.
PROCEDURE• Bring together the two half-flanges• Connect the two half-flanges at one point only so that the
flange can still be opened to the outside
• Place both half-flanges on the fitting between the back of the raised face and the rim of the fitting
• Close the two halves together. Place the sealing gasket and tighten the bolts and nuts gradually as shown in the Bolt Tightening Sequence for fixed flanges
• Tighten to the same bolt torques as given for fixed flanges
BOLT TORQUESThe following charts indicate the approximate bolt torques requiredto seal flanged joints against internal pressure.
The torque values are applicable for the type of gaskets specifiedand bolts, nuts and washers should be free from damage, rust etc.and must be lubricated on all mating services before assembly.
The relationship between applied torques and the actual loadimparted is not precisely predictable, therefore the values in thecharts are, of necessity, an approximate guide.
Approximate bolting torques using 3mm thick 70 IRHDrubber gaskets.
PN16 Flanged Joints

GASKET INSERTION• Ensure that the
gasket is clean
• Squeeze the gasket into a heart shape as shown:
• Insert the gasket into the socket ensuring that the hard retaining heal of the gasket is firmly bedded into the seating groove.
• Press the loop until the gasketfits evenly into the holdinggroove.
• To facilitate the bedding of the gasket in pipes DN800 and greater, it is advisable to form a second loop on the opposite side. The two smaller loops canthen be easily bedded into their final position.
• The inner edge of the gasket must not exceed the edge of the centring bead.
• After the insertion of the gasket, apply a thin layerof lubricant to the gasket.
JOINTING
• Apply a thin layer of lubricant onto the spigot end for an approximate distance of 50mm.
• Support the joint clear of the bottom of the trench.
• Enter the spigot into the socket, for insertion depths please refer to the table above.
• Ensure that the axes of the bedded socket and spigot joints are aligned centrally with each other.
• Use a pipe-laying tool to insert the spigot into the socket until the first marking line is no longer visible.
• After assembling the joint fully, examine the position of the gasket with a feeler gauge.
All spigot ends must be chamfered prior to assembly. It isrecommended that the chamfer is in accordance with thefollowing sketch.
Prior to cutting or inserting of the spigot, you must ensure that thepipe is not oval.
OVALITYWhere pipes are to be cut to form non-standard lengths, theContractor shall comply with the manufacturer’s recommendation in respect of ovality correction and tolerances to the cut spigotend. (CESWI Clause 5.15.2)
OVALITY CORRECTIONTwo methods are recommended for ovality correction. Note thatHam Baker Pipelines do not supply the equipment required.
Method 1The use of this is recommended where it is possible to remove thetackle after ovality correction and subsequent jointing.
• Position the timber strut and jack (approximately 5 tonnes capacity) inside the spigot end at 90º to the major axis. Rubber / timber pads should be placed in position to prevent possible damage to the pipe lining.
• Extend the jack until the ovality iswithin the tolerance specified in clause 5.3 on page 4
• Complete the jointing operation with the major axis of the spigot vertical.
• After jointing, remove the tackle.
When jointing into couplings, it may be necessary to use two jacksin order to obtain a ‘round’ profile.
Method 2The use of this method is recommended where it is not possible toremove the tackle described in Method 1, after ovality correctionand subsequent jointing.
• Place the tackle around the spigotend of the pipe at a positionapproximately 450mm from the pipeend with major axis of the spigot
vertical. Where pipes are sleeved or tape wrapped, rubberpads or similar should be placed between the re-roundingtackle and the protection system to prevent damage.
• Tighten the two nuts evenly until the ovality is within the tolerance specified in clause 5.3 on page 4
• Complete the jointing operation with the major axis of the spigot vertical.
• After jointing, remove the tackle.
CUTTINGPipes cut on site must be bevelled and rounded after cutting.
Re-coat the spigot end immediately after cutting.
After site cutting of spigot end re-apply the insertion markings asper table opposite.
The delivered pipes up to DN 300 are cutable along the length ofthe pipe barrel, to within 1m distance to the socket joint, so that aconnection can be effected.
Pipes over DN 300 are only suitable when marked with a continuouslongitudinal line. Those pipes have to be ordered separately.
There is additional marking on the socket’s face: ‘SR’ for ‘gaugedpipe’. When cutting CM-lined pipes, you should always wearprotection glasses and a breathing mask.
CLEANINGClean both the spigot end and the inside of the socket free of soilexcess paint etc.
LUBRICANTApply a thin layer of lubricant to thegasket seating position inside the socket.

APPLICATION
The anchor/BRS gaskets are used where:
• Where the joint tries to pull apart.• When laying a pipeline on steep slopes.• Temporary above ground installations.
JOINT PREPARATION - CLEANING
Prepare and clean joint as per standard gasket.
GASKET INSERTION
• Squeeze the gasket asshown below. Care must be taken when forming the heart shape so that the loop is between the stainless steel teeth.
• Insert the gasket as shown previously.
JOINTING
• Apply a thin layer of lubricant onto the spigot end for an approximate distance of 50mm.
• Support the joint clear of the bottom of the trench.
• Using a pipe-pulling tool, pull the spigot into the socket until contact is made with the gasket stainless steel segments.
• Continue to push the pipe until contact is made with the stainless steel teeth.
DEFLECTION
• Once the joint has been assembled, the pipes can be deflected up to 3º.
• A deflection of 1º over a 6 metre pipe, provides a deflection of approximately 100mm from the axis of the pipe or fitting previously installed.
DISMANTLING
• Apply lubricant to the disassembly segments.
• Insert the segments into the socket under the gasket together with carrying anvil.
• Drive the segments under the gasket around the whole circumference by hitting the anvil with a hammer.
• Withdraw the anvil.
• Apply the pipe-pulling tool over the joint and draw out the spigot from the socket.
• Discard the used gasket. Never re-use an anchor gasket.
Jointing Procedure -BRS System
Do not remove lifting device until connection has been made
14DISMANTLING
Newly installed pipes and fittings can be easily unassembled.
• Secure the pipe with the appropriate strength sling, around the pipe near the opposite end to that being dismantled.
• Raise and lower the pipe/fitting within the specified deflection limits whilst keeping it under tension or:
• Apply the pipe-pulling tool over the joint as shown below.
• Should the separation of the joints prove to be more difficult, then the joint can be separated using a clamp and pinion jack as detailed below.
This section provides guidance for the careful safe handling, off-loading and storage of ductile iron pipes and fittings, which willensure a long-term, trouble-free life. It is still the responsibility ofthe end user to comply with Health and Safety Regulations.
1. PIPES
1.1 BundlesPipes in the size range DN 80 to 350 are supplied in bundles asdetailed in Table 1. Each layer is supported with wooden battens.Pipes in the size range DN400 to DN800 are supplied as individualpipes. Their weights are given on page 13.
Table 1
1.2 Off-Loading1.2.1 If using a crane ensure adequate lifting equipment is
available and have sufficient capacity to offload the bundleweight detailed in Table 1.
1.2.2. Never attempt to lift the bundles by the restraining straps.
1.2.3 Only use webbing slings (x2). Each sling must have a safe working load of two metric tonnes and have a minimum length of fourteen metres. Never use chains or wire ropes as these might slip. They will also damage the external coating of the pipes.
1.2.4 Do not attempt to lift multiple pipes loose with slings. Only lift single pipes or complete bundles.
1.2.5 Ensure that the crane operator has a clear field of visionwhilst offloading. Should he not have a clear view then a person must guide him from a safe position.
1.2.6 It is recommended that guide ropes are used whilst off-loading pipe.
1.2.7 If using a forklift ensure that the forklift truck is capable of lifting the pipe bundles.
1.2.8 Ensure that the ground is hard and level.
1.2.9 Forks must be positioned underneath the protective bands around the bundle.
1.2.10 Care must be taken when removing the slings from the pipes.
1.2.11 The steel straps, which hold the bundles together, should be cut using plate shears only. Never use chisels, crowbars, picks etc. as this could damage the protective coating of the pipes.
1.2.12 Any damage to the coating or lining of the pipes and fittings must be immediately repaired prior to installation.
1.3 Stacking1.3.1 Each pipe bundle is secured to two wooden batons, which
can be laid directly onto a level hard standing surface.
1.3.2 Bundles can be stacked one on top of another, with the axes of the pipes parallel.
1.3.3 The maximum height pipe bundles can be stacked must not exceed five bundles. This may vary dependant on the ground conditions.

TYPICAL ARRANGEMENT OF A DRYWELL PUMPING STATION
Dry well pump stations site the pumps in a dry chamber, whichdraws from an immediate adjacent wet well. Dry well pumpstations facilitate ease of servicing the pumps. Isolating gatevalves are installed on both the suction and deliver side of eachpump, which allows the pumps to be inspected in line.
Due to high building costs this type of pump station is normallyused on large capacity installations.

TYPICAL ARRANGEMENT OF A (WETWELL) SUBMERSIBLE PUMPING STATIONAND VALVE CHAMBER
Submersible pump stations are the most common type of pumpstation, which provides and extremely cost effective installation forboth civil construction and M+E contractors.
Submersible pump stations are installed in a single undergroundchamber and are usually located at low points in the pipeline.
Submersible pump stations provide submersible pumps in the wetwell with motor control centre mounted above. The stations aredesigned where the pumps can be removed and replaced withoutdewatering the wet well or requiring personnel to enter the wetwell. All valves, pipe work and surge control equipment aremounted in a separate valve chamber outside of the wet well tofacilitate access.
Flanged pipes installed as self supporting spans are subjected toadditional stresses in addition to those caused by internalpressure; due to bending moments caused by their own weightand the weight of their contents.
The length of unsupported spans of flanged piping is limited by theneed to keep stresses due to the combined effects of internalpressure, and bending moments within safe limits.
All flanged pipes are designed to operate safely at the allowabletest pressure (PEA) when subjected to a bending moment causedby self weight and weight of contents equivalent to a simplysupported span of 10m for DN 80 to 250 and 15m for DN 300 to800 with a flange joint at the mid span position.
In practice, flanged pipes are usually installed as continuous orfixed beams and by careful design it is best to ensure that theflanged joints are located at zones of lowest bending moment.

RIVER CROSSINGIf the actual pressure in the pipeline is lower than the normal maximum rated pressure, higher bending moments may be permissible.Conversely any additional bending moment over that caused by self weight and weight of contents will reduce the safe spans.

AIR VALVES
Any pipeline conveying any fluid cannot operate efficiently unlessthe air is sufficiently vented from the system.
Accumulated gas or air will restrict the flow by reducing theinternal pipe area, it will also aggravate the effects of surge. Air orgas may build up because:
• Pipeline was fully charged with air/gas when empty• Air is drawn into the pipeline through faulty joints• Air/gas is released from the process medium due to changes
in temperature or pressure• Air or gas is trapped in pockets whilst the pipeline is
being filled• Air is entrained at the pump station
TYPICAL ARRANGEMENT OF APOTABLE WATER AIR VALVE
1. Hydro Coupling2. Double Spigot Pipe3. Double Spigot Pipe c/w Puddle Flange4. Flange on Double Socket Tee5. Clean Water Air Valve
Venting the pipeline is relatively easy, as air or gas tends to gatherat high points in the pipeline, optimum positioning of the air valveswill release the accumulated air or gas. It is recommended thatdouble orifice air valves are positioned at all high points and alongthe pipeline at approximately 750m intervals.

PIPES WITH PUDDLE FLANGES
Where a pipe passes through a concrete wall of a tank holding aliquid, below the liquid level, or the wall of a structure belowgroundwater level, a puddle flange (sometimes referred to as awater bar) is used to prevent the liquid seeping between theoutside of the pipe and the surrounding concrete.
Welded Puddle FlangeIf the puddle flange has towithstand thrust loading, then awelded puddle flange offerssecure through wall anchoragealong with a watertight seal. Awelded puddle flange can bepositioned on any pipeconfiguration as shown.
Split Puddle FlangeWhere no end thrust is expectedand the exact position is notknown then a split puddle flangemay be used, providing that thepipe has been produced by thecentrifugally spun method.
THE PROVISION OF FLEXIBILITY
Where a buried pipeline is built into a structure, differentialsettlement of the structure and the adjacent ground ispossible.Two flexible joints should be provided immediatelyadjacent to the face of the structure. This is generally referred to asa ‘rocker pipe’.
It is recommended that dimension A be as short as possibleconsistent with making the joint and dimension B as set out below:
