Foreword

SAPPCO DAMMAM

FACTORY

There has been a tremendous growth in the industrial, commercial,

and housing sectors and in all types of public amenities in Saudi

Arabia. For this growth, pipelines are needed to convey water and

sewage, and to protect telecommunication and electrical cables. To

fulfill this need, Saudi Plastic Products Co. Ltd. was formed with the

aim of producing, in Saudi Arabia, a full range of unplasticised

polyvinyl chloride (UPVC) pipes and fittings to internationally

recognised standards and Saudi Arabian Standards.

SAPPCO-DAMMAM also manufacture:

- CPVC pipes for Hot water distribution systems

- Polyethylene (PE100/PE80) pipes for various services

applications

- Polyethylene sub-duct/miniduct for Fibre Optic

Cable/Telecom.

- PVC pipes to American Standards

Our model factory in Dammam Industrial Estate is equipped with the

most advanced extrusion systems available today and we are able to

supply complete UPVC, CPVC and HDPE pipelines at relatively short

notice for either new projects or additions to, or replacement of,

existing pipe lines.

We are confident that pipe of our manufacture is especially suited to

the needs and environment of Saudi Arabia and the surrounding

Countries and are proud that SAPPCO by producing pipes locally is

contributing to the industrialisation of Saudi Arabia.

SAPPCO DAMMAM FACTORY was formed with manufacturing

capacity of 14000 Tons of pipe products.

Our affiliated company APLACO in Riyadh manufactures UPVC and

CPVC pipe fittings designed to standards for use with SAPPCO

pipes. The Comprehensive range of fittings is available from our

factory stores.

Introduction This is a technical handbook for the engineers who designs and

installs water and sewage pipelines and it contains the most

up-to-date information now available, based on world wide know howand technical knowledge.

The period of pioneering the use of UPVC pipes for the distribution of

water and sewerage is past and UPVC is widely established

throughout the world because of it’s many advantages over other

materials.

High quality pipes are manufactured within a EN ISO 9001:2008

certified quality management system.

In addition to the Riyadh Plant SAPPCO have built a model factory in

Dammam and equipped it with the most modern machinery available,

using many automated techniques to produce UPVC pipes to

exacting standards.

The accumulated knowledge of our Technical Advisors is freely

offered to engineers and our Technical Service Department is

available at all times to offer guidance and advice on the use of

SAPPCO UPVC pipes.

Hot water

drainage

Surface Temperature due

to discharge of hot water

Theoretically pipes and fittings made from UPVC are unsuitable for use

with very hot water and this is true for continuous flow at full bore.

However, pioneering work carried out in Great Britain established design

criteria that became adopted into their national standards. From this

acceptance of UPVC drainage system, the Market grew until it now has far

greater sales and use than any other above ground system and is

rapidly following the same trend with below ground drains and sewers. The design criteria was verified and tested by development of a Hot &

Cold Cycle Test and its principles have been adopted by many other

National Standards Organisations, ISO, Government and Private Test

Establishments.

The work carried out on UPVC drainage pipe work produced the following

design criteria:

1. UPVC has natural insulating properties.

2. Each increment of wall thickness has its own insulating value thus the

thicker the pipe the less transfer of heat through the wall thickness. So

constant water flowing at 90°C will only produce a surface temperatureof 60°C on the outside surface of a pipe with wall thickness 3.2 mm

(See Fig. 2).

3. A discharge of short period for about 20-30 minutes will be necessary

for the above transfer of heat to occur.

4. The softening point of UPVC plays an important role in the above

situation.

Although the temperature of the inside wall of the pipe has exceeded the

softening point, the external surface temperature is well below. Thus the

pipe and fittings remain rigid and able to resist loadings imposed by

expansion, contraction and soil pressures in the case of buried drains.

Also, normal discharges, from the most powerful washing machines and

domestic appliances will not harm UPVC Drainage Systems.

Similar tests have been devised for below ground applications, but using a

lower discharge temperature to ensure that below ground drainage also

meets the same service life expectancy.

The Combination of generous wall thickness

and high softening point provides safe limits

for maximum service life.

exceeding 60°C.

Handling and

Storage

Fig 6

Unplasticised PVC pipes are strong but light, their specific gravity being

approximately one-fifth of Cast Iron. As a result, these pipes are more

easily handled than their metal counterparts. Reasonable care, however,

should be used at all times, and when off loading, pipes should be

lowered, not dropped to the ground.

Pipes should be given adequate support at all times. Pipes should not be

stacked in large piles, especially in warm temperature conditions, as the

lower layers may distort; resulting in difficulties in jointing and pipe

alignment. Any pipe with ends prepared for jointing (socket and spigot

joints, ‘A’ joints, etc) should be stacked in layers with sockets placed at

alternate ends of the stack and with the sockets protruding to avoid

unstable stacks and the possibility of imparting a permanent set to the

pipes.

For long-term storage, pipe racks should provide continuous support, but

if this is not possible, timber of at least 3in. (75mm) bearing width at

spacings not greater than 3ft. (915mm) centres for pipe sizes 160mm andabove, should be placed beneath the pipes and at 6ft. (1.8m) centres at

the side, if the stacks are rectangular. These spacings apply to pipe size

160mm and above. Closer supports will be required for sizes below

160mm. In such pipe racks, pipes may be stored not more than seven

layers, or 6ft. (1.8m) high, whichever is the lesser, but if different classes

of pipe are kept in the same racks, then the thickest classes of largest

diameter must always be placed at the bottom.

For temporary storage in the field, where racks are not provided, the

ground should be level and free from loose stones. Pipes stored thus

should not exceed three layers high and should be stacked to prevent

movement.

Stack heights should be reduced if pipes are nested, i.e. pipes stored

inside pipes of larger diameters. Reductions in height should be

proportional to the weight of the nested pipe compared to the weight of the

pipes normally contained in such stowages.

UPVC pipes should always be stored in the shade to avoid ultra-violet

(U/V) degradation from the sun’s rays. Effect of UV Light refer to page 30

of this catalogue.

Since the soundness of any joint depends on the condition of the spigot

and the socket, special care must be taken in transit, handling and storage

to avoid damage to the ends.

When loading pipes on the vehicles, care must be taken to avoid their

coming into contact with any sharp corners such as cope irons, loose

nail-heads, etc., as pipes may be damaged by being rubbed against these

during transit. Whilst in transit, pipes shall be well secured over their entire

length and not allowed to project unsecured over the tailboard of the lorry.

Pipes may be off-loaded from lorries by rolling them gently down timbers,

care being take to ensure that pipes do not fall one upon another, nor on

to any hard or uneven surfaces.

Instructions

Cutting and Chamfering

Solvent Weld

Joints

Jointing procedure

Pipe should be cut square. A simple method of cutting pipes square is to

wrap newspaper or similar sheet paper around the pipe with no overlap

of the edges. Mark line around pipe (felt pen is ideal). Cut to line with

a fine toothed saw.

Pipe ends should be chamfered at an angle of approximately 15°C to

about 1/3 of the wall thickness with a coarse file, Surform tool or

chamfering tool.

Pipes up to 75mm may be jointed easily with solvent adhesives. Larger

sizes required more special techniques and require two men to make

such joints.

1. Mark depth of entry of the pipe into the socket and alignment mark.

2. Make small chamfer on the edge of the pipe end with medium file.

Fig 7a

Fig 7b

Fig 8

17/38

3 . Roughen the outside of the pipe and the inside of the socket using

sandpaper or emery cloth upto the entry mark.

4 . Clean both surfaces and remove all dust, grease and swarf using a dry

clean cloth and cleaner.

5. Stir solvent adhesive thoroughly. Use proper solvent adhesive.

6. Apply adhesive without delay after cleaning, using a flat clean and

proper brush. Apply an even unbroken layer brushing axially to the pipe

end and socket mouth with a heavier layer on the pipe. Where loose fits

are found, the pipe should be given a second coat.

7. Immediately insert the pipe into the socket up to the entry mark, align

pipe and socket. Hold in position for a few seconds, then wipe off excesscement.

8 . Solvent Weld Jointing of large diameter pipe requires special care. Use

sufficient hand power to maintain proper alignment and to bottom pipe in

socket / fitting.

instructions on the can observing any warnings.

10. Always use the Solvent adhesive supplied and approved by SAPPCO

or APLACO. TEST CONTENTS IN ACCORDANCE WITH

INSTRUCTIONS ON EACH CAN.

11. Joints should not be moved or disturbed for initial set time depending

on size. Then the jointed pipe may be handled with care. Allow 4 hours if

the jointed pipe lengths are to be laid in a trench.

12. Allow 8 hours to elapse before applying working pressure or 24 hours

for test pressures. With pipe sizes up to 50mm it is possible to reduce this

time. Allow 1 hour for each 3.5 atmospheres of pressure.

13. Read the precautions for “Solven Weld Joints” on page18.

Cleaner and cements are extremely

flammable and must not be stored orused near heat or open flame. Read

all warnings on cleaner and cement

cans.

NOTE : All solvent-welded PVC pipeline systemsshould be filled and/or flushed with waterimmediately after installation and curing toremove all flammable cement vapors. Failure to flush a new line leaves a

dangerous potential for inadvertment

ignition of any residual cement vapors.

Brushes must be clean and dry before commencing solvent welding.

Brushes must be thoroughly cleaned after use by washing out in

Do not dilute solvent adhesive with cleaning fluid.

Use Solvent adhesive and cleaning fluid in a well ventilated area. Keep

away from naked flames and do not smoke. Always replace lids of

containers, in any event, attention is drawn to the instructions printed on

the containers.

When laying continuous runs of pipe, joints may be made quicker than

the setting times advised above. The joint will not be disturbed with long

lengths, providing that the pipe is not twisted or the previously made

joint lifted out of place.

Ensure that the spigot and socket are free from dust, grit, grease and as

dry as possible.

Insert pipe into the socket without seal ring in place and mark pipe when

it is fully inserted.

Place seal in groove of socket ensuring that seal is correct way round.

Rubber seal rings should be fitted with tapered section facing the

outside of the socket.

Apply jointing lubricant to the chamfer and the end of the spigot of thepipe or fitting only.

Push the pipe firmly into the socket up to the insertion mark previously

made. If an expansion gap is required the pipe is then pulled back by

the desired amount. See Fig. 13 on page 21.

Jointing Clamps may be used for ease of assembly. The Clamps are

available in two sizes, one for pipes 90mm to 160mm O.D. and the other

for 225mm to 315 mm O.D. (See Fig. 10).

Where plastic pipelines incorporate metal valves or other heavy fittings it

is essential to support the valve directly rather than allow their weight to be

carried by the plastic pipe.

For the same reason it is usually advisable to fix pipe supports on either

side of flanged connections.

For light duty and small pipe sizes, plastic pipe support brackets are

suitable. For heavier duty installations, matching formed metal pipe

supports should be used with cork or P.E. liner for fixed points.

Plastic pipelines need to be supported at specific intervals. These intervals

will depend on the specific gravity of the material being conveyed, the

temperatures of the liquid and the environment and the pipe wall thickness

and type of plastic used. Some deflection may be allowed between

brackets and at changes of direction. The average deflection between

centres should be up to maximum of 2.5mm.

Pipe Supports—

Loose and Fixed

Arrangements

Axial movement of the pipe line must not be prevented, loose brackets

or sliding points allow the pipe to move or slide as expansion or

contraction taken place.

Fig 12a

To ensure that this movement is controlled it is necessary to create fixed

points. Fixed points may be positioned at one end of a pipe run, at

bends or changes of direction or in the centre of a pipe run.

Fig 12b

A fixed point may be created in pipeline by solvent welding two split

collars on to the pipe. The collars should be positioned and clamped for

12 hours. Collars may be manufactured from pipe, a section of

approximately 1/3 of circumference removed.

General Notes

A. As with all pipe jointing, cleanliness is of prime importance, and

pipes, specially spigot ends, should be supported clear of the ground

to prevent dirt being smeared on with the lubricant. Placing the pipes

on blocks also reduces friction and consequently facilitates the

making of the joint. THESE BLOCKS MUST BE REMOVED BEFORE

BACKFILLING, AND EVERY CARE MUST BE TAKEN TO ENSURE

THAT THE PIPE IS NOT BEDDED ON SUBMERGED ROCK.

B. The pipeline should be tested initially after a few joints (certainly

not more than 500 metres) to ensure that they have been made

correctly, and subsequently at convenient intervals, preferably not

exceeding 1000 metres.

C. All changes of direction must be anchored. (See Fig. 14b.)Concrete thrust blocks are suitable but the unit should only be

haunched and a flexible membrane interposed between the concrete

and the unit, to protect it against damage by abrasion.

D. Before testing, the line must be backfilled leaving the joints

exposed. If the joints must be covered, it is useful to mark their

position.

E. The pipe should be marked so that the spigot enters the socket to

within 13 to 25mm of the bottom of the socket dimension. The depthof chamfer should be one third the wall thickness.

F. Never cut the leg of a Ring Seal Joint bend. Some distortion of the

shape may occur during processing which might cause a leak.

G. If jointing above ground, observe the depth of entry after installation.

H. UPVC Pipes may be cold flexed to accommodate ground contours

and road curvatures in outside diameters up to 225mm. The bending

radius (R) should not be less than approximately 300 times the

outside diameter of the pipe (in mm). The cold bending and

supporting is illustrated in Fig. 14a, for standard pipe length of 6

metres.

Pipes larger than 225mm diameter should be regarded as rigid and

changes in direction should be accommodated by the use of special

bends of flexible couplings.

Stone free tampered soil in order to prevent the spigot from being

It is very important when laying UPVC pipes for gravity drainage to

ensure that the pipe is laid in accordance with the recommendations

made on the following pages. These are extracted from the U.K.

Ministry of Housing and Local Government’s Working Party report on

the design and construction of underground sewers, but are equally

applicable to pressure pipes.

The trench should not be opened too far in advance of pipe laying and

should be backfilled as soon as possible. The width of the trench at

the crown of the pipe should be as narrow as practicable but not less

than the outside diameter of the pipe plus 300mm to allow proper

compaction of the sidefill, 225mm above the crown of the pipe, the

trench may be any convenient width. The inherent flexibility of UPVC

drainage pipe can be used to advantage but care must be taken to

ensure that the bed of the trench will support the pipeline adequately

so as to prevent localised loss of gradient or bridging. Projections

must be removed to avoid point loading of the pipe.

Material for Bedding

and Sidefilling

Bedding andSlidefilling

Backfilling

Some soils, as excavated from the trench (such as free drainage

coarse sand, gravel, loam and soil of a friable nature) may be suitable

for use as sidefill material, but they must be capable of being

compacted sufficiently to provide adequate support for the pipe (see

note following for test for suitability). Soils such as hard chalk which

break up when wet, and clay should not be used immediately around

the pipe for bedding, sidefill or backfill, unless a rotary type excavator

has been used. Should the material excavated form the trench be

unsuitable, then a backfill medium, which complies with U.K.B.R.S.

tests described at the end of this section must be used. Granular

material is very satisfactory as it requires little compaction once

placed, but any material which complies with the U.K.B.R.S

recommendations is suitable.

With flexible pipes it is of great importance that the sidefill should be

very firmly compacted between the sides of the pipe and the soil sides

of the trench. Any trench sheeting should be partially withdrawn to

allow this to be done.

Before backfilling, any levelling pegs or temporary packing should be

removed. The thickness of the bedding under the barrel of the pipe

should be not less than 1/3 of the diameter, and a minimum of 100mm

thick. In very soft or wet conditions, or where the bottom of the trench

is very irregular, this thickness should be increased as necessary to

give a suitable bed.

The bedding should be thoroughly compacted in layers not more than

150mm thick to give a uniform bed, true to gradient, on which the pipe

may be laid. Pipes should be laid directly on this bedding. Bricks or

other hard materials must not be placed under the pipes for

temporary support. Further bedding material should be placed

around the pipe and be thoroughly compacted in 75mm layers by

careful tamping up to the crown of the pipe, eliminating all cavities

under the two lower quadrants of the pipe.

The same material should then be placed over the crown of the pipe

for not less than 2/3 or the diameter, with a minimum height of 100 mm

and a maximum of 300 mm and be thoroughly compacted. The

Process of filling and tamping should proceed equally on either side

of the pipe, so as to maintain an equal pressure on both sides.

Normal filling of the trench should then proceed in layers not

exceeding 300mm in thickness, each layer being well rammed.

Heavy mechanical rammers should not be used until the fill has

reached a depth of 300mm above the top of the pipe. Special

consideration and selection of back filling material will be necessary if

the risk of surface subsidence is an important consideration, for

example under roads.

When pipe lines are layed in hot climatic conditions it is

advisable to fill the pipe with cold water to bring the pipe lengths to normal

contracted dimension. Check the joints in the case of dry jointed or ring seal

joints to ensure that socket insertion depth is satisfactory.

Fig. 16

For special cases of unstable ground and areas of mining subsidence

where “draw” of the joints may be expected, telescopic joints should be

used throughout the line, though most flexible pipes are capable of

following any ground movement of normal degree without fracture of

failure.

For the necessary reaction from the sidefill to develop, it is necessary for

some deformation or ovality of the pipe to take place. Until more is

known on the subject, the United Kingdom Building Research Station

consider that the maximum acceptable decrease in vertical diameter is

5%, because above this figure there is a risk of blockage, leakage from

joints or collapse of the pipes.

(a) PARTICLE SIZE

The maximum particle size should generally not exceed 20mm. The

presence of an occasional particle between 20mm and 40mm is

acceptable provided the total quantity of such particles is only a verysmall fraction of the whole. If particles over 40mm are present the

material should be rejected. In cases of doubt, a weighed

representative* sample of material - about 2kg - should be sieved** using

20mm and 40mm sieves. If any particles are retained on the 40mm

sieve, the material is not acceptable unless it is first screened so as to

comply with this requirement.

(b) EASE OF COMPACTION - Apparatus required.

1. Open-ended cylinder 250mm long and 150mm ± 6mm internal

diameter, (160mm Class 3 Sappco UPVC pipe is suitable).

2. Metal rammer with striking 40mm diameter and weighing 1 to 1.25 kg.

3. Rule.

Obtain a representative sample more than sufficient to fill the cylinder

(about 11.5kg) it is important that the moisture content of the sample

should not differ materially from that of the trench. Place the cylinder on

a firm flat surface and gently pour the sample material into it, loosely and

without tamping. Strike off the top surface level with the top of the

cylinder and remove all surplus spilled material. Lift the cylinder up clear

of its contents and place on a fresh area of flat surface. Place about 1/4

of the material back in the cylinder and tamp vigorously until no further

compaction can be obtained. Repeat with the second quarter, tamping

as before, and so on for the third and fourth quarters, tamping the final

surface as level as possible.

Measure down from the top of the cylinder to the surface of the

compacted material. This distance in mms divided by the height of the

cylinder (250mm) is referred to as the Compaction Fraction.

* To obtain a representative sample, about 50kg of the material should be

heaped on a clean surface and divided with the spade down the middle

into two halves. One of these should then be similarly divided and so on,

until the required weight of sample is left.

** In the sieving, clumps of material that break up under light finger

pressure may be helped through the sieve, but considerable force must

not be used to squeeze oversize clumps through the mesh.

0.1 or less (25mm) — Material suitable

0.1 or 0.3 (25mm to — Material suitable but requires extra care

75mm) in compaction. Not suitable if the pipe is

subject to waterlogged conditions after laying.

Over 0.3 (75mm) — Material unsuitable.

Whether under roads and verges or in open country, UPVC pipes may be

buried with a maximum cover depth of 6.1 metres.

However, a minimum cover depth of 1.2 metres should be allowed when

pipes are installed under roads. Tests have shown that traffic loads

(wheel loads) do not affect pipes with this amount of cover depth

provided they are properly installed and back-filled. At depths less than

1.2 metres, special consideration should be given to all the engineering

factors involved, such as class of road, its construction and the position

of other services. Under these circumstances, concrete may be used asa protecting raft above the pipeline, provided a cushion of fill is laid

between the pipe crown and the raft.

In open country, where top loading is unlikely to occur, pipes may be laid

with a minimum cover depth of 0.45 metres without any protection. At

depths less than 0.45 metres, elsewhere than under roads, concrete

slabs on a cushion of fill materials above the pipe should be used as a

protection against picks, gardening implements, etc.

28/38

Soil Loading

(non Pressure)

Because UPVC pipes are an inherently flexible material, results obtained

from a crushing test such as that carried out on conventional rigid

materials give figures that in no way relate to the performance of the pipe

under trench conditions. A rigid material such as cast iron, cement

asbestos or salt glazed pipe, when subjected to a compressive load will

show virtually no sign of deformation. it is possible to increase the loaduntil a point is reached where the pipe will fail without further noticeable

deformation. Similar tests carried out on UPVC pipes cause deformation

at a relatively low load. Any increase in the load causes the pipe to be

considerably deformed although removal of the load allows the pipe to

return almost to its original shape. To get a true picture of UPVC

drainage pipe performance, tests have been devised by the U.K.

Agreement board, the U.K Building Research Station and The British

Plastics Federation, to simulate ground conditions. All tests are

conducted on the basis that 5% is the maximum allowable deformation.

110mm and 160mm domestic drainage pipes are subjected to a

maximum temperature of 86°C for short periods. They are therefore

subjected to hot and cold water discharges over 2,500 cycles to

represent statistically a 50-year usage. During the cycling period a load

of 8,000 Ibs per square foot (3628.7kg per .092sqm) is applied to the pipe

backfill approximately 2 ft. (.609m) above the crown of the pipe. Pipes

above 160mm diameter are not subject to such a high elevated

temperature. Tests on larger diameter pipes have therefore been

conducted assuming continuous discharge at lower temperatures. Once

again a static load is applied continuously and on pipe sizes above

160mm is 9000 Ibs (4082.3 Kg) for 200mm and 250mm, and 315mm

10,000 Ibs (4535.9 Kg).

In the design of pipe the U.K. Ministry of Housing and Local Government

Working Party has recommended that pipes laid under fields, etc., should

be designed to support two wheeled loads each of 7,000 Ibs. (3175.1 Kg)

each, spaced 3 ft. (.914m) apart, with an impact factor of 2 in addition to

the weight of the backfill. For pipes laid under roads carrying traffic, the

two wheel loads should be 16,000 Ibs. (7257.4 Kg) each, spaced 3 ft.

(.914m) apart, with an impact factor of 1.5. The effect of surface loading

diminishes with depth and theory indicates that for a 110mm pipe at 3 ft.

(.914m) a static load of 2 by 16,000 Ibs (7257.4 Kg) would produce only

slightly more effect than that of 2 by 7,000 Ibs. at 2 ft. (3175.1 Kg at

.609m). Also, it is the proportion of the pipe vertically below one wheelthat is mainly affected. The contributory effect of the second wheel 3 ft.

(.914m) away adds only 5% extra at 3 ft. (.914m) and 10% extra at 2 ft.

(.609m). The effect of increasing pipe diameter increases the projected

area of the pipe subjected to load to a maximum of 10,000 Ibs. (4535.9

Kg.) Therefore on 110mm pipe the load is 8,000 Ibs. (3628.7 Kg), 160mm

pipe 8,000 Ibs. (3628.7 Kg) and above this size as quoted above. These

tests are designed to simulate the worst possible operating conditions

but notwithstanding this, the maximum deformation of 5% is still not

exceeded. Work is continuing in this field both on a practical and

theoretical basis by the plastics industry as a whole, with a view to giving

engineers further information on the design aspects of UPVC drainage

pipe.28

Hydraulic Testing

of Pipeline

Important Notes

29

The pressure testing of pipeline shall be conducted with water at interval

initially not exceeding 500 meters and subsequently not exceeding 1000

meters. Pipe should be adequately anchored to prevent movement. The

joint and the pipeline should be slowly filled with clean water taking care

to prevent surge and air entrapement. All entrapped air must be purged

from the line before applying pressure. All air release valves should be

installed at high points and a further precaution against air entrapement

is to pass a foam swab through the pipe line. The passage of foam swab

will additionally clean the line of any debris left in the line during laying.

The temperature of test water should be preferably maximum 23°C.

When testing above 23°C please use safety factor given in Table 6 of

page 9 in this catalogue.

The test pressure and duration shall meet the requirements of local

regulations where applicable.

The line should be pressurised to 1.5 times of the System DesignOperating Pressure but not less than 15 psi nor in excess of the pressure

rating for pipe or appurtenances. Measure the pressure at the lowest

elevation possible.

The duration of pressurization shall be preferably 1 hour but not to

exceed 3 hours.

All visible leaks or any leak in excess of the permitted variation should be

repaired and the pipeline retested following the same procedure.

1. Pipeline systems should be constructed to avoid excessive water

hammer / surge pressure. (see details on page 30)2. Air must be purged from pipelines before applying pressure

3. Joint must be covered and protected from heat and UV resistance,

particularly in the mid day time.

4. Allow 24 hours for line test pressure with pipe sizes upto 50mm it is

possible to reduce the time or 8 hours to elapse before working

pressure.

5. PVC Non-pressure pipelines installed are tested to low pressures for

a specific period of time (leakage tests).

6. In hot weather pressure test in early morning is recommended.

WARNING

• NEVER use compressed air or gas in PVCpipeline.

• NEVER test PVC pipe and fittings withcompressed air or gas.

• ONLY use PVC pipe for water and approvedchemicals.

Use of compressed air or gas in PVC pipe and fittingscan result in explosive failures and cause severeinjury or death.


30/38

Water Hammer

Considerations

Effects of

Ultra-Violet (UV) Light

Surge pressures due to water hammer should be considered when

designing a piping system. A momentary pressure rise occurs when

liquid is started and stopped quickly, and is caused by the momentum of

fluid. Pressure rise increases with the velocity of the liquid, the length of

the piping system from the fluid source, or with an increase in the speed

of starting or stopping. For example hydraulic shock occurs when valves

are opened or closed quickly, or pumps are started with an empty

pipeline.

Proper design when laying out a piping system will eliminate the

possibility of hydraulic shock damage. The following suggestions shall

help to avoid the problems:

1. In any piping system, including thermoplastic, a fluid velocity not

exceeding 1.52m/sec. will minimize hydraulic shock effects, even with

quick-closing valves.

2. Using actuated valves with a specific closing time will reduce the

possibility of inadvertent opening or closing of a valve too quickly. With

pneumatic and air-spring actuators, it may be necessary to place a valve

in the air line to slow down the valve operation cycle.

3. Evaluate flow at pump start-up and during shut down. Also determine

how much air, if any, is introduced during pump start-up.

4. If possible, when starting a pump, partially close the valve in the

discharge line to minimize the volume of liquid that is rapidly accelerated

through the system. Once the pump is up to speed and the line

completely full, the valve may be opened.

5. Use surge control devices and standpipes wisely to give flow storage

during surge. Check valves can be used near pumps to help keep lines full.

6. Use properly sized vacuum breaker-air relief valves to control the

amount of air that is admitted or exhausted throughout the system.

For any further assistance do not hesitate to contact our Technical SalesDepartment.

UPVC pipeline systems when continuously exposed to ultraviolet (UV)

radiation from sunlight, PVC pipe can suffer surface discoloration. This

is commonly termed “UV degradation or sunburning,” colour change to

brown due to UV attack.

1. UV degradation or sunburning affects PVC when energy from the UV

radiation causes excitation of the molecular bonds in the PVC. The

resulting reaction occurs only on the exposed surface of the pipe and to

extremely shallow depths of 0.025 to 0.076 mm. Degradation does not

continue when exposure to sunlight is terminated. The study found that

exposure to UV radiation results in a change in the pipe’s surface colorand a reduction in impact strength. Other properties are not adversely

affected.

2. The most common method used to protect above-ground PVC pipe

from the sun is painting with a latex (Water-based) paint. Preparation of

the surface to be painted is very important. The pipe should be cleaned

to remove moisture, dirt and oil, and then wiped with a clean, dry cloth.

Petroleum-based solvents and paints should not be used, since the

presence of petroleum will prevent proper bonding of paint to pipe.

3. The color of the paint is of no particular importance. However, white

color is recommended as it helps to reflect the sunlight.

4. Burial of PVC pipe provides complete protection

5. Pipe should be stored in the shade.30
