    1. Jointing Procedure 1.2 Using Solvent Cement

    1. Cut the pipe square using a fine pitch hand saw.2. To remove burrs use a medium file. The end of the pipe must be chamfered with a 2mm x 450 average

    chamfer

    3. The pipe and fitting should be marked. This will help determine proper penetration of pipe into socket.4.5.6. Lightly abrade pipe and fitting, then clean the contacting surfaces thoroughly by using a clean rag and

    cleaning fluid.

    7. Apply sufficient Solvent Cement to Pipe and fitting using a clean brush. The number of coats neededwill vary depending on the diameter of pipe and fitting. About one or two coats are usually needed.

    8. Assemble joint immediately. Avoid twisting and hold the pipe and fitting together for 1 5 second s for %& 60 Seconds for 8" pipe. A pipe joining device should be used when pipe with a diameter of 6" or more

    is to be joined. This will ensure full entry of spigot.

    9. Remove excess cement10. Close solvent cement in tightly.11. Clean brush after use.12. DO NOT Smoke near can, DO NOT leave can near p[en flame, AVOID skin contact, DO NOT inhale.

    Solvent Cement 500 ml.

    Notes:

    All Solvent Cement must be carefully used in accordance with the instructions on the can. Never dilute with other

    fluids. Joint cannot be done properly in wet, oily or dirty conditions.

    Drying time will vary according to amount of Solvent Cement applied, ambient temperature and testing pressure.

    Temperatures of more than 250C (760F) will reduce the jointing time from 3 minutes to approximately 1 minute.

    Full rated pressure should not be applied for at least 24 hours.

    2. Underground lnstallation 2.1 General Requirements

    lnstallation to be according to the relevent Codes of practise and to the manufacturer's recommendations.

    t The trench should not be opened too far in advance of pipe laying and should be backfilled as soon aspossible.

    0 lf pipes are joined above ground before being laid in the trench, they should be brought to the temperatureof the ground and backfill material in order to avoid contraction.

    I Excavation should be made under the bell of each pipe so that the entire length of the pipe, except the bell,will be supported on the bottom of the trench.

    t Atany changeof direction, anchoring byconcrete blocks must be provided. Aflexible membrane isrecommended between concrete and fitting for protection.

    a Mechanical rammers should only be used above 300 mm from the pipe crown.

    0 After testing, exposed joints should be filled by pad gravel, compacted and the backfilling should follow,

    0 For water distribution, disinfecton of pipes isessential before the system is put into use (also sometimesduring use). The pipe should be flushed (velocity at least 2 ft. per seconds), then refilled with

    chlorinated water with a dose of 50-100 ppm. At the end of 5 hours, chlorine residual should not be less

    than 5 ppm.

    2. Underground lnstallation 2.2Trench Preparation & Bedding

    This recommended practice describe procedure for installing single wall thermoplastic pipe in excavated

    trenches. Consideration should be given to allowable deflection due to pipe/soil interactions.

    When preparing the trench, certain conditions may be encountered which require special treatment in order to

    provide adequate bedding and foundation.

    1. The trench width below the top of the pipe affects the soil load imposed upon the pipe. Therefore, thiswidth should not be greater than that necessary to provide adequate room for joining the pipe and

    compacting the haunching and initial backfill.

    When unstable trench walls are encountered, this condition must be stabilized before laying the pipe. To

    obtain the desired lateral support for laid, the trench width should be a maximum of 5 pipe diameters;

    othenruise sheeting, trench box or any other method would be used to control such conditions. ln some

    severe cases, well points or under-drain may be used to control excessive ground water conditions.

    The trench should be as narrow as possible. lf trench width is greater than 6 pipe diameters , launching

    and initial backfill should be compacted to at least 2.5 pipe diameters on either side of the pipe.

    When an unstable trench, bottom condition is encountered, it must be stabilized before laying pie, or an

    alternative foundation should be utilized. A 150 mm layer of processed stone or gravel, of suitable grade

    and which the unstable soilwill not be penetrate, should be used. This material should be compacted.

    lf the trench is over - excavated below a point of 150mm from the bottom of the pipe, but not beyond a point

    of 30mm, it would be necessary for this area to be filled with an embedment materialand compacted.

    However, if the trench is more than 300mm deeper than the bottom of the pipe, return fill and ram

    selected stone-free soil to within 100mm. Then proceed as in para 4.

    6. Bedding material should be to grade along the entire length of the pipe to be installed. Differentialsettlement is to be avoided and blocking should not be used to bring the pipe to grade.

    Materials used for bedding, haunching and initial backfill are as follows:

    TYPEI Angular,6mm to 12mm (1/a" to/2 ") graded stone. When used for bedding a depth of 100mm to'l50mm is generally sufficient to provide uniformity with little or no compaction due to the nature of

    angular particles. Type 1 is also suitable for haunching and initial backfill.

    TYPE II Coarse sands and gravels with maximum particle size of 12mm ( % "). fhis type is also suitable forbedding. However , when in use for haunching and initial backfill, place initial backfill in two stages in

    order to prevent movement of the pipe: Stage 1 - to the top of the pipe, Stage -2 to at least 150mmover the top of the pipe. Mechanical or hand tamping compaction should be used.

    TypE lll Fine sand and clayey gravel. ln bedding this type should be well compacted. ln haunching and initialbackfilling it should be used in the same way as Type ll, but with maximum compaction.

    TYPE lV Earth and debris of rocks larger than 20mm ( % ") diameter and other materials. This type is notsuitable for bedding, haunching or initial backfill. lt is used for the filling itself, to cover the trench. A

    layer of about 800mm (31.5') over the initial backfill before the trench is well loaded and a layer of

    about 1200mm (47") before utilizing a hydro - hammer during compaction.

    Back filling should be carried out between joints to pressure testing. After testing joint should be

    covered with TYPE lorTYPE llmaterial, provided particles largerthan 12mm ('/r")have been taken

    out. Then continue as mentioned above for the rest of the backfill.

    Requirements for bedding and backfill is practically the same as sewer pipes except for few items:

    a) Haunching and backfill materials are of 12mm (%") particle size of smaller and surround the pipecompletely. Type "lll" is recommended as materials, also Type 1, provided particles are 12mm and

    smaller.

    Sand and gravel containing a significant proportion of fine-grained material, such as silt and clay, should

    be compacted by hand, preferably by mechanicaltamper.

    During trench cover and fill-up, rocks of 76mm (3") and above must be removed; rolling equipment or

    heavy tampers should only be used to consolidate the final backfill.

    When pipe has been assembled on top of the trench, it is advisable to cool the pipe to ground tempera-

    ture before backfilling to prevent pull out due to thermal contraction.

    When rubber-ring joints are used, suitable anchoring methods should be used to prevent excessive

    longitudinal or bending movement of the piping : anchor points are at all sudden changes in direction,

    Such as elbows, tees, bends, etc.. it is necessary to withstand the pressure thrust.

    f) lf pipes are jointed above ground, they should remain undisturbed for 2 hours before being 'snaked' in tothe trench. Particular care should be taken to ensure pipes and jointing materials are thoroughly dry

    when following the jointing procedure.

    ln overall use, gravel with fines and sands is the best backfill material for pressure pipe. Sand and gravel

    mixed with silts and clays, in which sand or gravel constitute at least 50% of the mixture, is also suitable.

    3. Design Aspects 3.1 Supports

    Because of thermoplastic high co-efficient of thermal expansion, special attention should be given during design

    to control expansion. Support should be provided at adequate intervals.

    1. Fixing support and expansion joint distances for soil and waste systems:

    2. Fixing support and expansion loops for pressure system.

    Expansion Loops:

    When designing an above ground system maximum partical changes in direction should be inkoduced to allow

    for expansion. When these changes of directions cannot be naturally introduced, loops or expansion units

    should be integrated.

    It should be borne in mind when designing that both ambient external temperature and internal liquid tempera-

    ture affect the expansion of the systems.

    To calculate pipe wall temperature change, the following equation can be used:

    AT = 0.65 ATL + 0.10 ATAAT = Change in average temperature of pipe wallATL = Maximum change in temperature of pipe contentsAT = Maximum change in temperature of external air.

    3. Design Aspects

    Flexibility and sizing of loops can be determined by

    using the graph.

    Example:

    Determine the loop size required in a straight 4 inuPVC pipe with a leg length of 20 meters: waterflow through the pipe at temperature varyingbetween 200C and 400C and the external airtemperature varies between '150C and 450C.

    ,1. TO CALCULATE MID PIPE WALL

    TEMPERATURE CHANGE (^T)AT = 0.65 ATL + 0.10 (45-15)

    i.e.

    AT = 0.65 X20 + 0.10 X 30 = 16oC

    2. TO CALCULATE EXPANSION o41= AT x Lxtherefore

    AL = 16 x 20 x (7.0)x 10{

    3. TO CALCULATE LOOP SIZE

    Using the value of LLl2draw a horizontal line on thegraph from the vertical scale to meet the 4in. Pipegradient line. Drop a perpendicular from the intersec-

    tion point to the horizontal scale. The figue obtained

    is the length of loop offset required = 10.1 x102 =101Omm.

    The distance between loop legs should not exceed

    5 Storage & Handling

    uPVC pipes and fittings should ideally be stored in a well ventilated and shady area. However,when pipes need

    to be stored in the sun and to protect from UV light, they should be covered in a way wich leaves the end of pipes

    open for air to pass through. This should keep heat accumulation to a minimum.

    A six month exposure to sunlight will change the colour of uPVC pipe. This will be limited to 0.15 mm in depthafter approximately 12 month exposure.

    Elstomeric rings should be stored in the shade and fitted in the socket when the pipe in the trench and ready for

    jointing.

    Solvent Cement and cleaning fluid should always be stored in a cool and dry place.

    Pipe should always be stored on level and flat ground which is free from stones and sharp projections. Wooden

    planks with a minimum widths of 75 mm (3 inches)whose centers are one metre (yard) apart, should be used.

    Stacking of individual pipes should not be more than one meter high.Stacking of bundles of pipes is possible

    upto three metre high. Nested pipes should be kept at bottom of stack. Larger diameter pipes of sufficient wall

    thickness should be kept at the bottom of a stack or in a lower bundle. Loose pipes should have side supports

    which are not more than 1.5 metre apart. For heavier pipes ('l60mm or 6" and above), bundles should not be

    stacked more than two metres high. The principle is to reduce the load on lower rows of pipe as much aspossible either by having smaller and lighter pipe on top and distributing the weight of the upper rows of pipes

    as much as possible by using wooden planks or bundle frames.

    Pipes and components should be unloaded from lorries by hand in order to avoid damage. Forklift trucks will

    have to be used for bundles and large unit loads.
