Foreword

SAPPCO DAMMAMFACTORY

There has been a tremendous growth in the industrial, commer cial, 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 elec trical 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.

Hot waterdrainage

Surface Temperature dueto 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 temperature of 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 thicknessand high softening point provides safe limitsfor maximum service life.

External Surface,temperature notexceeding 60°C.

Pipe Lengths andJoints

SAPPCO pipes are available in nominal total standard lengths of 6 meters. Other lengths can be supplied by arrangement.

SAPPCO pipes are supplied with various joint systems.

1 : Plain End / Chamfered end. (Fig. 4a)Plain Ended (P/E) pipe for use with separate Couplings; Ring Seal, Solvent (Adhesive) Weld or Special Fittings. Pipe can also be supplied with both ends chamfered (D/C) if requested, in lengths of 6 metres.

2 : Plain Solvent Weld joint (Fig. 4b)Plain socket (P/S) Solvent Weld Joints. Pipes are supplied with an integral plain socket preformed in our factory. They are jointed using the recommended solvent adhesive supplied by SAPPCO and using the techniques specified on Page 16, 17 and 18.

3 : Rubber ring seal joint (Fig. 4c)Rubber ring joints (R/J). Pipes are supplied with integral grooved socket at one end incorporating elastomeric sealing ring. SAPPCO manufacture the world wide known Anger joint system, the Anger joint sockets are made with locally wall thickened pipe. In these joints, the rubber ring seal is so designed that the sealing power increases with the rise in internal pressure in the pipeline. For jointing procedure refer to page 18.

1 : Coupling with / without registerCouplings with double ring seals or solvent weld joints are supplied by SAPPCO for jointing plain ended pipes or when pipes are cut and jointed to required length. These couplings may either be with register or without register, the latter type being used for repair or alteration work in the existing lines. For specific diamensions refer to page 34, Table 16.

Handling andStorage

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 and above, 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.

Cutting and Cham fering

Solvent WeldJoints

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.

Page 17: Upvc Pipe Fitting

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 excess cement.

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.

9. Always replace the lid of the can after making a joint and follow the 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 or used near heat or open flame. Read all warnings on cleaner and cement cans.NOTE : All solvent-welded PVC pipeline systems should be filled and/or flushed with water immediately after installation and curing to remove all flammable cement vapors. Failure to flush a new line leaves a dangerous potential for inadvertment ignition of any residual cement vapors.

Fig 10

Brushes must be clean and dry before commencing solvent welding. Brushes must be thoroughly cleaned after use by washing out in cleaning fluid.

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 the pipe 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).

Ring seal joints should not be used on above ground installations unless all the joints are anchored against end thrust.

UPVC Pipelines must be protected from direct sunlight and external heat, Please refer to page 30 “Effect of UV light”

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 FixedArrangements

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 depth of 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.

Excavation

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 Beddingand 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 normalcontracted dimension. Check the joints in the case of dry jointed or ring sealjoints to ensure that socket insertion depth is satisfactory.

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 SIZEThe 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 very small 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 suitable0.1 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 as a 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.

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 load until 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 wheel that 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 Testingof 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 Design Operating 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 pressure3. 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 PVC

pipeline.• NEVER test PVC pipe and fittings with

compressed air or gas.• ONLY use PVC pipe for water and approved

chemicals.Use of compressed air or gas in PVC pipe and fittings can result in explosive failures and cause severe injury or death.

Page 30: Upvc Pipe Fitting

Water HammerConsiderations

Effects ofUltra-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 Sales Department.

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 color and 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 protection5. Pipe should be stored in the shade.
