    General

    HDPE Pipe Material Advances

    Features and Benefits

    During the past 40 years or more, since HDPEwas first used to manufacture pipes, there havebeen considerable strides made in improving thequality of material and its long term ability towithstand pressure.

    The first SABS specification (SABS 533) madeuse of a design stress of 5 mPa. This specificationhas now been superceded by SABS ISO 4427which covers 3 different material grades viz:PE63, PE80 and PE100. These three material

    grades have different properties which enablethem to be classified with minimum requiredstrengths (MRS) of 6.3 MPa, 8.0 MPa and 10.0MPa respectively. Applying a design coefficient of1.25 (safety factor) to the MRS gives the designstress used by SABS ISO 4427 for these materials(5.0 MPa, 6.3 MPa and 8.0 MPa respectively) withthe result that the wall thickness for a particularsize and class becomes progressively less as thechange is made to a material with a higher MRS.

    Quality Assurance

    Applications

    Lamasat International (Z) Ltdhas been a SABS mark holder for over 7 years.

    Products are manufactured to the relevant SABSspecifications at its plants in Lusaka.Manufacturing facilities conform tothe ISO 9001 of 2000 Quality Managementsystem.

    Fully audited Quality Control laboratories areoperational in Lusaka,

    where scheduled and random testing of productsis carried out.

    Lamasat International have for several years beenconfidently supplying their range of HDPE pipes,Compression fittings andSaddles for successful use in a variety ofpotable water applications in the Civil, Agricultural,Municipal, Mining and Industrial sectors. Because

    of the good chemical resistance and abrasionresistance properties they are also extensivelyused in chemical, waste and slurry applications.

    Pipe Dimensions

    In this table it can be seen that SABS ISO 4427have grouped together the different pressureclasses, produced from different material

    designations, under a common heading known asthe Standard Diameter (Dimension) Ratio or SDR.The minimum wall thicknesses specified are notexactly that which would be derived from acalculation using Barlow's formula or the SDR butare the rounded up values of the highest minimumwall thickness calculated for any size and class inthe SDR group (see Design Stress and SafetyFactor on page 8).

    Specifications

    The HDPE pipes manufactured by LamasatInternational are manufactured to, and carry theSABS mark for, SABS ISO 4427. These pipes are

    Physical Properties

    Table of Physical Properties

    High Density Polyethylene (HDPE) is athermoplastic material which is supplied by themanufacturer in a 'ready to use' pelletised form.There are several different grades available. Theparticular grades suitable for pipe manufacture arereferred to as PE 63, PE 80 and PE100. The pipemanufacturer simply converts this material intopressure pipe.

    The properties given below are for HDPE pipematerials. It should be noted that many of theseproperties are relative to temperature and the

    duration of stress application.

    The internationally accepted method forcalculating circumferential hoop stress is derivedfrom Barlow's formula and is as follows:

    s= p(d - t)/2t

    where: p = internal pressure (MPa) t = minimum wall thickness (mm) d = mean external diameter (mm) s= circumferential hoop stress in wall of pipe (MPa)

    The Stress Regression Line for HDPE is givenbelow.

    s

    Principal stress/time curves for PE 80 and PE 100 pipes at 20C and 80C. The standardcurve for HDPE Type 2 at 80C (acc. to DIN 8075) is shown in comparison. Theminimum required strength (MRS) at 20C and 50 years is 10 MPa for PE 100 and8 MPa for PE 80 giving the design stress 8 MPa and 6.3 MPa, respectively.

    The Stress Regression Line

    The traditional method of portraying the primarymechanical property of HDPE, tensile strength, isby means of a graph of log stress vs log time tofailure. This is known as the stress regression line.It is a plot of the circumferential hoop stress in thewall of the pipe (from internal pressure) againsttime to failure.

    Numerous actual test results, measured at 20Cand 60C, over a range of times up to 10,000hours, are plotted on a log log scale and aregression line is calculated to fit this data. Theresultant regression line is then extrapolated to 50

    years (438,000 hours). The method of calculationis an internationally accepted procedure describedin ISO/TR 9080. The required values of stress andtime are specified in SABS ISO 4427.

    Design Stress and Safety

    Factor (service factor)

    Safety factors take into account handling

    conditions, service conditions and othercircumstances not directly considered in thedesign.

    In terms of SABS ISO 4427 the minimum safetyfactor is 1.25. This factor, when applied to theMinimum Required Strength (MRS), for theparticular material classification (e.g. PE80,PE100), gives the maximum allowable hydrostaticdesign stress for the designated material.

    The relationship between MRS and for variousdesign coefficients is as follows at 20C.

    The design engineer may wish to apply a greatersafety factor depending on operating conditionsand environmental considerations.

    Applying Barlow's formula (below) it is possible tocalculate the minimum wall thickness for any givensize and pressure class of pipe.

    t = p x d (2s+ p)

    where: t = minimum wall thickness (mm) p = internal pressure (MPa) d = mean external diameter (mm) s= design stress (MPa)

    For example the minimum wall thickness for a250 mm Class 10 HDPE pipe made from PE 80material is:

    t = 1.0 x 250 / {(2 x 6.3) + 1.0}

    = 18.38 mm

    Round up to 18.4 mm for manufacture and/or theappropriate SDR for the Class and Materialdesignation.

    Melt Flow Index

    Tensile Strength

    The Effect of Temperature

    Change

    The melt flow index of polyethylene materials is ameasure of the mass of melted material, at 190C,that will pass through a specific orifice in 10

    minutes when subjected to a specific pressure.

    The melt flow index (MFI) is largely dependant onthe molecular mass. Higher molecular massesresult in lower MFI because long, well packedmolecules do not flow as easily as short, lesspacked molecules.

    Since both density and MFI are decisive for thestrength properties they are regulated in moststandards for polyethylene pipes.

    In terms of the SABS specification the Melt FlowIndex must conform to the raw materialmanufacturers pipe grade specification. Thisinformation can be obtained from the the rawmaterial manufacturers data sheets.(Also see Table of Physical Properties on page 6)

    The tensile strength of polyethylene materialsincreases with an increase in molecular masssince long, well packed molecules are more

    difficult to separate.This property is also effectively regulated bystandards.(See Table of Physical Properties on page 6)

    Working Pressure:

    The standard design temperature for HDPE pipesis 20C and working pressures are usually quotedfor this temperature. HDPE pressure pipesfunction perfectly well below 20C right down tofreezing point and can in fact, withstand higherpressures than those quoted at 20C.As can be seen from the stress regression lines,the creep rupture strength diminishes withincreasing temperature and working pressuresmust be down-rated if the same factors of safetyare to be maintained. The applicable reductionfactors are given under Temperature

    Sub Zero Temperatures:

    Water has been known to freeze in HDPE pipeswithout causing fractures, but permanent straincan result, leading to severe reduction in the

    working life of the pipe. Hence HDPE pipes - likeother pipes - should be protected against sub zerotemperatures.

    Expansion and Contraction:

    All plastics have high co-efficients of expansionand contraction several times those of metals.This must be allowed for in any installation by theuse of expansion joints, expansion loops etc.

    It should be noted that it is possible to change theimpact strength of certain plastic materials,however this usually comes at the expense of

    properties such as tensile strength, hardness orstiffness. This property is therefore effectivelyregulated (as with density and MFI) by moststandards.

    Impact Resistance

    Ultra Violet Resistance

    Flammability

    Abrasion Resistance

    HDPE pipes, when manufactured to SABS ISO4427, contain 2.5% (by mass) of carbon black.This provides exceptional protection against the

    effects of ultra violet light.

    As with impact resistance, it is possible to improvethe fire resistance of HDPE by the addition ofvarious compounds. Again this comes at theexpense of other properties. Fire resistance ismeasured by a limiting oxygen index (LOI).

    A number of international investigations to assessthe abrasion resistance of various plastic materialshave been carried out. Generally the results ofsuch investigations are expressed as a loss ofvolume in relation to the original wall thickness.The results to date have varied in regard to theabrasion resistance of various pipe materials.However, what they all show is that plasticspossess superior abrasion resistance relative toother pipe materials.

    For example, in one investigation, HDPE pipessuffered wear to the extent of 4mm after 1600hours while the corresponding wear occurred insteel pipes after 1000 hours.

    Jointing

    One of the greatest features of HDPE pipes is thefact that a wide variety of jointing systems is

    available to suit a whole range of applications.The jointing systems can be divided into two maincategories with further sub-divisions in eachcategory.

    General

    The Lamasat System

    Butt-fusion jointing is a thermofusion processwhich involves the simultaneous heating of theends of two components which are to be joineduntil a melt state is attained on each contactsurface. The two surfaces are then broughttogether under controlled pressure for a specificcooling time and homogeneous fusion is formedupon cooling.

    The resultant joint is resistant to end thrust andhas comparable performance under pressure tothe pipe.

    This method of jointing requires an electricallyheated plate to raise the temperature of the pipeends to the required fusion temperature and isused for PE63, PE80 and PE100 grades ofmaterial for pipe of size 32mm and above of thesame Standard Dimension Ratio (SDR).

    When jointing pipes using butt-fusion techniques,the heater plate temperatures are the same forPE63, PE80 and PE100, 195C to 200C.

    Note:The Site Fusion Jointing Specification WIS 4-32-08 Issue 2, 1994 emphasises the importance for thebutt-fusion machine to be able to control the reducedsecondary ram pressures that are now required for dualpressure butt-fusion jointing. For SDR11 pipes of sizes250mm, 280mm and 315mm and for all pipe (SDRs 11,17.6, 26) of size 355mm and above the butt fusionpressures should be reduced after 10 seconds andtherefore the use of an automatic butt fusion machine isrequired. (These conditions are tabulated on page 15.)

    Depending on the design and make, butt-fusionmachines may or may not be capable of acceptingfittings as moulded for direct welding to pipes.

    Lamasat therefore offers two ranges of fittings forbutt-fusion systems to provide the greatestflexibility in this regard : long spigot fittings 'pupped' fittings

    Pupped fittings are fabricated by butt-fusing (in thefactory), 0.5m lengths of pipe to each leg of aspigot fitting, thereby allowing the straight lengthof pipe to be gripped by clamps of the butt-fusionmachine.

    The Lamasat butt-fusion system comprises,therefore: Straight polyethylene pipe

    Long spigot fittings Pupped fittings Accessories

    Pre-Welding Checks

    Before commencing a welding operationcheck that: There is sufficient fuel for the generator to

    complete the joint and that it is functioningcorrectly before it is connected to the machine.

    The heater plate is clean and residues fromprevious welds have been removed.

    A tent is available to provide shelter duringwelding.

    The machine is complete and undamaged.

    You know the correct welding parameters for themachine and pipe being welded. The heater plate is at the correct temperature.(Connect the heater plate to the power supplyand retain for at least 20 minutes inside thethermally insulated guard). To remove dirtdeposits the heater plate may be washed, whencold, with copious quantities of clean water atthe start of the jointing session. Only clean, lintfree materials must be used to clean the plate.To remove grease and oily films the plate maybe wiped with lint free material dampened by asuitable solvent, eg. Isopropanol.

    Check that the pipes and/or fittings to be jointedare of the same size, SDR and material.

    Dummy Welds

    Even though washing may remove large depositsof dirt, very fine particles of dust may still remainon the heater plate. To remove such dust it isnecessary to make a dummy joint at the start ofeach jointing session, whenever the plate hasbeen allowed to cool below 180C, or at a changeof pipe size. Two dummy must be made if the pipe

    size is greater than 180mm.A dummy joint can be made using pipe off cuts ofthe same size, SDR and material as the pipebeing installed. It is not necessary to actuallymake a joint. The procedure can be discontinuedafter the full heat cycle.

    Manual Welding Procedure

    Place the pipes in the clamps with the endsagainst the trimming tool and with the pipemarkings aligned.

    Align and level the components using thesupport rollers. Tighten the pipe clamps to grip and re-round the

    pipes. Cover the free ends of the pipes to prevent

    cooling of the plate by internal draughts. Switch on the trimming tool and close the clamps

    slowly so that the pipe ends are moved againstthe trimming tool until continuous shavings arecut from each surface.

    Keep the trimming tool turning whilst opening theclamps to avoid steps on the trimmed surfaces.

    Remove the trimming tool taking care not totouch the trimmed ends.

    Remove loose shavings from the machine andcomponent ends.

    Do not touch the prepared surfaces.

    Check that both surfaces are completely planed.If they are not then repeat the trimming process.

    Close the clamps and check that there is novisible gap between the trimmed faces.

    The maximum permitted outsider diametermismatch is:

    1.0mm for pipe sizes 90mm to 315mm 2.0mm for pipe sizes 316mm to 800mm. If the mismatch is greater than these values then

    the pipe must be realigned and re-trimmed. Open and then close the clamps and note the

    drag pressure needed to move the pipestogether using the hydraulic system.

    Drag pressure is the minimum gauge pressure

    required to overcome the sliding frictional drag onthe rams due to the operation of the machine andthe weight of the pipes/fittings being jointed.

    Note: The drag pressure (in bar) must beassessed accurately prior to making each fusion

    joint and must be added to the basic ram pressurevalues shown on the machine.(When fully automatic machines are used thisoperation will normally be carried outautomatically.)

    Remove the heater plate from its protectivecover. Check that it is clean and up totemperature.

    Place the heater plate in the machine and closethe clamps so that the surfaces to be joined are

    touching the plate. Using the hydraulic systemapply the pressure previously determined.

    Maintain the applied pressure until the pipebegins to melt and a uniform bead of 2-3mm isformed on each end. After the initial bead up, the pressure in thehydraulic system shall be released so that thepressure gauge registers between zero and thedrag pressure so as to control the bead growthduring the heat soak time. Check that the pipedoes not slip in the clamps. The pipe ends mustmaintain contact with the heater plates.

    When the heat soak time is completed, open theclamps and remove the heater plate ensuring

    that the plate does not touch the meltedsurfaces.

    Immediately close the clamps (within 8 to 10seconds of removing the plate) and bring themelted surfaces together at the previously

    determined pressure.

    Maintain the required pressure for the minimum cooling time as indicated in the table. After this time the assembly can be removed

    from the machine but should not be handled fora further period equal to the above cooling time.

    Examine the joint for cleanliness and uniformityand check that the bead width is within thespecified limits.

    Remove the internal beads, if required, using suitable debeading tools. The beads and joint should be numbered/coded

    using an indelible marker pen. The beads will be twisted at several positions. If the bead is seen to split at any point then thejoint must be cut out from the pipeline and thejoint remade. If a similar defect re-occurs, allfurther jointing must cease until the equipmenthas been thoroughly cleaned, examined andnew trial joints made and shown to besatisfactory.

    The Rules of Butt-Fusion

    NEVER

    Attempt to weld together pipes of different SDR(wall thickness). Touch trimmed pipe ends. Leave trimming swarf inside pipe or on welding

    machine. Allow equipment to get wet or dusty. Use non-approved machinery. Remove a weld from the machine before cooling

    time has elapsed. Allow untrained personnel to use welding

    equipment. Cut corners in any part of the welding procedure. Weld pipes of different material on site. (In

    factory controlled conditions it may be possible todo this).

    Use a generator of inadequate capacity.

    Fittings

    Pipe fittings can be manufactured from pipe in awide variety of sizes and pressure classes butmostly from 75mm OD upwards and Class 6 orhigher. The fittings can be plain ended (for buttwelding, electrofusion fittings or compressionfittings) or have stubs fitted for flanges or TechClamps. Permissible working pressure is 60% ofclass of pipe used to fabricate fitting, e.g. 10 barpipe produces a 6 bar fabricated fitting.
