Neproplast Upvc Pipes

FOREWARD
NEPROPLAST (New Products Industries) was established in the 1969 as the rst manufacturing facility to introduce the uPVC piping systems to the market in Saudi Arabia. Since its establishment, NEPROPLAST has followed
a strict policy in producing high quality pipes. Using state of the art equipment and tools in its production facilities,
hiring a highly trained professional staff, and working with a very experienced team of consultants in the industry.
The initial production of NEPROPLAST uPVC pipes were manufactured according to British Standard Specications BS 3505/3506. At a later stage, NEPROPLAST started to manufacture pipes and ttings according to International Specications ISO. NEPROPLAST actively participated with Saudi Arabia Standard Organization SASO
to set the Saudi Arabian Standard SAS 14/15/1396. In the mid 80s, NEPROPLAST started the production of PVC
pipes and ttings according to ASTM standards for schedule 40, schedule 80, and CPVC pipes for sch80.
By producing a wide range of pipes and ttings according to different standards, NEPROPLAST has established
for itself a strong position in the market to serve the construction industry in the elds of water network pressure
lines, sewerage and drainage non-pressure lines, and electrical & telecommunication conduits . NEPROPLAST
made its pipes and ttings available in both options of Rubber Ring or Solvent Cement jointing systems.
In 2009, NEPROPLAST made a signicant move into modern, heavy metal free stabilizers for all its uPVC &
cPVC products. A move which ensured total elimination of toxicological content throughout the entire NEPROPLAST product range.Organic stabilizers pipes and ttings ensure a safe drinking water supply, free of any
possible toxic traces which can develop through the use of heavy metal uPVC stabilizers.
All NEPROPLAST drinking water products are now accreditised through NSF, proof of its excellent health safety
factor.
NEPROPLAST added to its products portfolio the production of Polyethylene pipes (HDPE) in 2009. NEPROPLAST HDPE products range covers pipes and ducts to serve the water, gas, electrical, and telecommunication
applications. NEPROPLAST recently introduced to the market the Polyethylene Corrugated-Optic-Ducts (COD) as
a unique product for ber optic and electrical cabling installations.
All NEPROPLAST products are marketed and sold through National Marketing Est. Co LTD. which has more than
23 branches covering all cities and urban areas across the Kingdom of Saudi Arabia. National Marketing has an
export department responsible for exporting NEPROPLAST products to Middle East and North African (MENA)
markets. In addition to NEPROPLAST products, National Marketing Est. Co. imports a wide range of ttings,
valves, solvent cements, and other accessory components. Nowadays, National Marketing Est. Co LTD. is considered the largest trading company in Saudi Arabia that has all kinds of plastic pipes, ttings, valves, and cements
available in its stocks for all traders and contractors in the Saudi market.
Both NEPROPLAST and NATIONAL MARKETING strive to be the largest quality leader in the supply of plastic
piping systems to serve the water, gas, electrical & telecommunication sectors across the Middle East.

CHEMICAL RESISTANCE OF NEPROPLAST uPVC PIPES

NeproPlast uPVC & cPVC pipe and ttinJs have excellent chemical resistance to most mineral acids, bases,
salts, and aliphatic hydrocarbons. When they are used within their allowable pressure and temperature
ranJes, they will provide a Jood alternative to metallic pipinJ which corrodes when exposed to the same
aJJressive chemical solutions. The information contained in the followinJ chemical resistance tables are
based on data supplied to us by our raw material manufacturers and some actual eld experience Jathered
from various sources. You must take into consideration the specic use conditions that will apply to your project. There will be variables that will affect the chemical resistance such as: temperature, pressure, chemical
concentration, and external stresses that may exist in the desiJn and construction of the system. Because of
the wide variety and numerous use conditions that are found in the process chemical industry, the nal decision to use thermoplastic pipinJ should be based on in-service testinJ and evaluation by the responsible enJineer and end-user.
INTERPRETATION OF THE DATA:
It is important to understand that an R ratinJ does not necessarily imply that pipe, ttinJs, and joints can be
used at their water pressure ratinJ and be expected to have the same lonJevity when used with a particular
chemical other than water. Generally, the chemical resistance of uPVC and CPVC will decrease with an
increase in temperature and concentrations. This is also true for all other components in the system that will
come in contact with the ow. Solvent cements, valves, instrumentation, o-rinJs, Jaskets, and other such
components should be evaluated and approved by their respective manufacturers.
R = Recommended For Use

GENERAL ADVANTAGES OF NEPROPLAST uPVC PIPES

Corrosion Resistance & Scale
Build up:
NeproPlast uPVC pipes are
chemically resistant to nearly all
acids, alkalis, alcohols, halogens
as well as many other corrosive
uids. Being non- conductor of
electricity, it eliminates galvanic or
electrolytic corrosion which is the
cause of expensive repairs.
NeproPlast uPVC non-corroding
properties ensure improved ow,
lower maintenance costs and
longer performance life.

Chemical Resistance:
Fire Proof:
NeproPlast uPVC pipe inhibit

excellent chemical resistance
against most acids, alcohols,
alkalis, salt solutions and
halogens. NeproPlast uPVC
pipes are also not adversely
affected
by
atmospheric
conditions and are well suited for
outdoor installations. For specic
applications see the NeproPlast
chemical resistance guide.
NeproPlast uPVC pipes do not

support combustion and are self
extinguishing. Pipes will not burn
unless an external ame source is
applied. NeproPlast uPVC pipes
are non-toxic and will not affect
taste, smell or color of drinking
water or any other liquid.
Extensive
tests
on
uPVC

are far lower than with alternative
piping
materials.
NeproPlast
uPVC piping systems are resistant to fungi and bacterial growth,
particularly those which cause
corrosion in metal piping systems.
NeproPlast uPVC pipes have lower

thermal conductivity than for metal
which reduces heat losses and
offer better uniform uid temperature, prevent "sweating" formation
of condensation on the pipe wall.
Insulation in certain instances, may
be completely eliminated.

APPLICATION OF NEPROPLAST uPVC PIPES

WATER SUPPLIES:
Non-toxic NEPROPLAST uPVC pipes will not affect the taste, color or smell of
drinking water. They will never corrode and are therefore extremely sanitary.
Deposits and scales will not build up inside as in the case for conventional steel
pipes. Their strength is greater than that of asbestos pipes. NEPROPLAST
REWDLQHG6$62&HUWLFDWLRQDQG16)IRUGULQNLQJZDWHUXVe.
IRRIGATION SYSTEMS:
NEPROPLAST uPVC pipes are ideal for agricultural irrigation and sprinkler
systems. Non-corrosive NEPRO uPVC pipes are perfect for carrying water which
contains chemical fertilizers and insect inhibiters. In thick wall and large diameter
NEPROPLAST uPVC pipes liquids can be transported under high pressure,
which is convenient for the management of large volumes.
NEPROPLAST UPVC PIPES CASING & SCREEN:
Engineering difFXOWLHV and the probability of adverse chemical reactions, make
it impractical to overcome corrosion and encrustation through the use of protective coating, chemical treatment or cathodic protection. Thus, NEPRO noncorrosion PVC pipes for water well casing and screens rapidly received approval
by the appropriate ministry consultants and engineers.
INDUSTRY:
Resistant to most chemicals, NEPRO uPVC pipes have an important role to play
in industrial plants. Light, noncorrosive, and easy to assemble, they allow more
complex piping work than with steel or cast-iron pipes.
SOIL, WASTE & DRAINAGE SEWER SYSTEM:

Waste lines for corrosive gases, ventilation for ofFH buildings and factories,
drainage systems for private homes and elevated highways these are a few of
the many possibilities for NEPROPLAST uPVC pipes. A full line of uPVC WWLQJV
is available to ensure easy installation.
MINING:
NEPROPLAST uPVC pipes particularly are well suited for draining corrosive
liquids found in mines. They make an ideal vent line for pits because they are
easily installed in hard to reach places.
ELECTRICAL & TELECOMMUNICATIONS CABLES:

NEPROPLAST uPVC pipes form an integral insulator, hence there is an everincreasing demand for them as electrical conduit. To facilitate work, a full line of
WWLQJVLVDYDLODEOHDQGIDEULFDWHGIURPWKHVDPHPDWHULDODVWhe pipes.

Unplasticized PVC pipes are strong but light, its specic gravity being approximately oneIth that oI cast iron.
As a result, these pipes are more easily handled than their metal counterparts. Reasonable care, however,
should be exercised at all times, and when oII loading, pipes should be lowered, not dropped to the ground.
Pipe 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 diIculties when joining and Ior pipe
alignment. Any pipe with ends prepared Ior joining (socket and spigot joints, RR joints, etc.) should be
stacked in layers with the socket, placed at alternate ends oI the stack and with sockets protruding to avoid
lop-sided stacks and the Imparting oI permanent set to pipes. Particularly in the case oI Ring pipe, rubber
rings should not be exposed to solar radiation Ior any length oI time iI they are not coated. It is recommended
to stock them in a cool and shady place. Rubber rings should not come in touch with chemicals, grease, oil
and to be stored Ior too long a time.
NON - EXPOSURE TO DIRECT SUNLIGHT
For long-term storage, pipe racks should provide continuous support, but iI this is not possible, timber oI at
least 75 mm bearing width at spacing not greater than 1 m centers Ior pipe sizes 150 mm and above, should
be placed beneath the pipes and at 2 m centers at the side, iI the stacks are rectangular. These spacing apply
to pipe size 160 mm and above. Closer supports will be required Ior sizes below 160 mm. In such pipe racks,
pipes may be stored not more than seven layers or 1.5 m high, whichever is the lesser, but iI diIIerent classes
oI pipe are kept in the same racks, then the thickest classes must always be at the bottom.
For temporary storage in the eld, where racks are not provided, the ground should be level and Iree Irom
coarse stones. Pipes stored thus should not exceed three layers high and should be staked to prevent
movement.
Stack heights should be reduced iI pipes are nested, i. e. pipes stored inside pipes oI larger diameters.
Reductions in height should be proportional to the weight oI the nested pipe compared to the weight oI the
pipes normally contained in such stowages.

Since the soundness of any joint depend 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 and or by rolling them gently
down timbers, care being taken to ensure that pipes do not fall one upon another nor on any hard or uneven
surfaces. Fork-lift trucks will have to be used for bundles and large unit loads.
DEFLECTION:
The ring integral socket permits an angular GHHFWLRQ at the joint of 2 to 3 degree The introduction of joint
GHHFWLRQ is however, generally unnecessary in an inherently H[LEOH uPVC pipeline. SufFLHQW H[LELOLW\ is
provided by individual pipe lengths to enable gentle curves to be negotiated without imparting GHHFWLRQ at
the joints.
As a general guide the cold bending radius R of a uPVC pipe length can be calculated as
follows

INSTALLATION
UNDERGROUND INSTALLATION TRENCH WIDTH PREPARATION COVER AND BACKFILLING
The width of trench for most purposes is enough to be 30 cm wider

than the diameter of the pipe to allow enough room for jointing.
Depth of cover should be at least 1 m from top of pipe to ground
surface (it is wise to consider in early planning stages how future
road widening plans could affect this depth of cover and to consider
the frosting depth according to the local climate).

When laying NEPROPLAST water mains piping the usual recommendations relating to sound pipe laying practice should be
followed. However, in view of the greater H[LELOLW\ of PVC than
most traditional materials,some of the procedures attain special
importance.
To avoid possible damage or deformation of the pipe, its support by the ground in which it is laid should be
made as uniform as possible, and materials in contact with the pipe must be free from large stones, sharp
edged LQWV or other hard objects. The trench bottom should be carefully H[DPLQHG for irregularities and any
hard projections removed. In good uniform conditions, where the trench bottom can be readily brought to an
even QLVK so as to support the pipes uniformly over their length no underbedding will be
necessary.Elsewhere and especially in rock or variable soils containing large stones, ERXOGHUVLQWVWUHH
roots or soft pockets a prepared bed is necessary. This bed should consist of suitable well compacted
selected granular material.
The ideal material for the trench bed and for compacting is one that will pass through a tin sieve but which is
free from very QH particles which may impede drainage. The thickness of bed should be a minimum of
150mm.
In all cases, care should be taken to remove any leveling pegs or temporary packing such as wooden
wedges, bricks or stones. Selected granular materials similar to the material used for bedding should then be
carefully placed and compacted in uniform layers alongside and under the pipe up to a height of 150mm or
more above the crown. Any trench sheeting if used should be partially withdrawn so as to ensure that the
spaces between the pipes and soil faces of the trench are completely OOHG with well compacted granular
materials in order to provide the necessary side support for the pipes and prevent H[FHVVLYH deformation
under load. It may be helpful especially when thin wall piping is being laid if the pipe can be full of water during
this operation.
Under roads or verges, or where mechanical plant is to be used for the placing and or compacting of the
EDFNOO the remainder of the UVW 300 mm depth of OO above the crown of the pipe should be compacted by
hand and should consist of selected, uniform, readily compactable material, placed and compacted in
uniform layers. The remaining OO should then be placed in layers of 300 mm. or more, depending on the compactors used.
If piping is laid in hot weather, precautions should be taken to allow for the contraction of the line which will
occur when it cools to its normal working temperature. The best method is to allow the pipe to OO with cold
water from its normal supply when the trench has only been partially EDFNOOHG This will result in the reduction
of the overall length of the pipe due to shrinkage and it will therefore be necessary, before QDO back OOLQJ to
carefully H[DPLQH any detachable or other joints to see that sufFLHQW reserve of draw is still available and that
they have not become subject to any undue stress.

The ideal material should be free from
large clay lumps (retained on a 3 in. sieve)
from stones (retained on a 1 in. sieve) and
sharp edged stones or LQWV vegetable
matter and from soil.

Above ground installation:
The jointing procedure for above-ground pipelines is identical to that for underground pipe lines. Aboveground installations should be fully VXSSRUWHG UPO\ enough to avoid strain on all joints but H[LEOH enough
to allow for a certain amount of thermal H[SDQVLRQ in a pipeline. All DQJHG joints should be supported on both
sides. Rubber ring joints should be anchored against end trust. Pipelines should be protected from abrasion
by metal supports with felt or foam rubber strips.
THRUST FORCES
When a pipeline is constructed using SXVKW MRLQWV joint separation due to internal pressure and resulting
thrust forces must be prevented. This is achieved using concrete trust blocks at directional FKDQJHV

The design of uPVC pipes provides a safety factor

apply a similar factor of safety after calculating

pressure.
PVC BEND
In view of the H[LEOH nature of uPVC it is desirable in thrustblock to install a design to permit the largest
possible area of contact between the WWLQJ concerned and the concrete block so that a restraint against
H[FHVVLYH H[LQJ as well as WKUXVW is provided (Fig.A). This IHDWXUH in certain soil FRQGLWLRQV may also be
applied to Solvent Welded pipelines which need no support against thrust but which can EHQHW by H[LQJ
restraint at abrupt directional changes.
Thrust block should not be allowed to encase the WWLQJ as the H[WHUQDO diameter of a uPVC pipe must be left
free to distend due to pressure XFWXDWLRQ The block may be designed as shown in (Fig.A) or if total encasement is preferred the WWLQJ should UVW be wrapped in several layers of heavy gauge Polythene OP prior to
concreting to provide freedom of movement and a barrier against abrasion.

The following information are intended to assist Engineers and Contractors to take full advantages of the
physical and mechanical properties of uPVC pipes and to achieve the desired results:
A) Method for rubber ring joint installation:
1. Ensure that the mating areas of spigot and socket are throughly clean.
2. Setting the rubber ring in grove.
3. Assess the full socket depth by simple measurement and mark spigot accordingly.
4. Apply lubricant to the spigot side and to the inside of the joint on rubber.
5. Accurate axial alignment of the spigot and socket prior to jointing is important, hand feed spigot
into rubber joint until resistance from the inner sealing section is felt.
6. Bar and block assembly is recommended because a worker is able feel the amount of force being used and whether
the joint goes together smoothly.
7.If undue resistance to pipe insertion is encountered , disassemble the joint and check the position of the rubber ring

B) Method of solvent welded joint installation:
1.Joint Preparation - Cut Pipe square with the axis, using a ne - tooth saw with a miter box or guide. Remove all burrs
and break the sharp lead edges.
2. Cleaning & Priming-Surface to be joined must be cleaned and free of dirt , Moisture ,Oil ,and other FOREIGN material
Applying Weld-On primer.
.Mark on spigot the full length of the socket side to make sure that the spigot will t exactly the socket length.
4. Application of solvent cement - PVC solvent cement is fast drying and should be applied as quickly as possible ,
consistent with good workmanship , Follow up the manufacturers recommendation to both spigot and socket side with
an adequate quantity of cement.
5. Joint Assembly - While both the inside socket surface and the outside surface of the spigot of the pipe are WET with
solvent cement ,forcefully bottom the spigot in the socket .Turn the pipe or ttings 1/4 turn during assembly (but not after
the pipe is bottomed) to distribute the cement evenly.Hold for a while until handling strength is developed. Assembly
should be completed within 30 seconds after the last application of solvent cement.
6. After Assembly -Wipe excess cement from the pipe at the end of the socket.Gaps in the cement bead around the pipe
perimater may indicate a defective assembly. Handle the newly assembled joints carefully after 1 hour.
Importance Points of Pipe Installation with Solvent Cement Joints
1. The joining surfaces must be clean and dry

2. Sufcient cement must be applied to ll the gap between male and female ends
3. The Assembly must be made while the surfaces are still wet and uid.
4. Completed joints should not be disturbed until they have cured sufciently to withstand handling.
5.Keep the solvent cement closed and shaded when not actually in use. Discard the solvent cement when a noticeable
change in viscosity occurs, when the cement does not ow freely from the brush, or when the cement appears lumpy and
stringy.
Although Nepro cement joints achieve initial setting in a very short time the joints does not reach its full strength for about 24 hours.
Therefore, cemented joints must be left overnight before pressure testing is carried out.

HYDROSTATIC TESTING
The length of test section will be determined by practical reasons such as availability of water, or the number
of pipes, ttings and joints to be tested. Long pipelines should be tested in sections as main laying
progresses.
The pipe length to be tested may be blanked off using a blank iron or Steel ange previously drilled and
tapped for test equipment connection and strutted as necessary against end thrust. The blank ange may be
attached to the pipeline by a Viking Johnson Flange Adapter or similar.
Testing should be preferably not be carried out against closed valves. All charging and testing should preferably be carried out from the lowest point of the under test section and all testing equipment should be located
at this point. The pressure gauge also should be located at the lowest point or adjustment must be made for
the level of the pressure gauge relative to the pipes position.
Prior to testing, care should be taken to ensure that all anchor blocks have attained adequate maturity and
that any solvent welded joints included in the pipe system have developed full strength. Correct support and
anchorage of any above ground section of the pipeline is also necessary. Underground pipelines should be
back-lled, taking particular care to consolidate around lengths which may have been deected to negotiate
curves. All joints may be left exposed until testing is completed.
With the stand pipe, valves and pressure gauge assembled, lling of the main can begin. The main should be
charged slowly, preferably from the lowest point with any air cock in the open position. They should be closed
in sequence from the lowest point only when water, visibly free from aeration, is being discharged through
them.
Satisfactorily charged, the main should be allowed to stand overnight to allow any residual air to settle-out
and percolate to the pipe soft. 5e-venting is then necessary and any water deciency should be made-up.
Pressure testing can then begin by pumping slowly until the required test pressure is attained. A single or
double cylinder hand pump should be used for this purpose. Mechanical pumps are not recommended unless
incorporating a pre-set blow-off mechanism.
The hydrostatic test specication will be at the discretion of the responsible Engineer but should not exceed
11/2 times the designed working pressure of the lowest rated component in the system and a time duration
of 24 hours.
A permissible water loss of 3 liters per kilometer of pipe per 25mm nominal bore, per 3 bar of test pressure,
per 24 hours,may be considered reasonable.
Air testing is not recommended If, however, for practical reasons, pneumatic testing is necessary, this should
be limited to a maximum pressure of 1.5 bar.
Air leakage can be detected by applying soap solution to the joints or by pre-odourising the air with Ethyl
Mercaptan.This will reduce the time duration of an otherwise long term pneumatic test.
During any air-pumping operations no one should be working on, or near, the test section and precautions
should be taken to avoid heavy objects striking the main whilst under pneumatic pressure.

THERMAL MOVEMENT
Where the temperature of a uPVC pipeline is likely to vary due to atmospheric temperature,it is important to
plan the variations in pipeline length which may arise as a result of temperature differences. Expansion and
contraction can be calculated using the formula.
Gl [ L [ Gt
dl = Change in length in millimeters
Where,
= 0.08mm/m/C.
L = Original length of pipe in meters
dt = Total temperature range in 0C.
Calculation of expansion and contraction should take account of the minimum and maximum foreseeable
temperature conditions.
When the total length variation of the pipeline has been established, the positioning of both support and
anchor brackets can be determined.
Anchor brackets, can be so arranged to sub-divide the total length variation and to control movement in a
VSHFLFGLUHFWLRQ6XSSRUWEUDFNHWVPXVWDOORZWKHSipeline to move freely.
It is normally possible by correct bracket arrangement to direct movement in such a manner that this is a
accommodated by directional changes in the line.
Expansion bellows may be used to accommodate excessive movement but in such instances the pipes so
connected must be restrained against possible separation.
$Q\OLQHYDOYHVPXVWEHUPO\DQFKRUHGDQGLQGHSHndently supported so that no stresses are transmitted to
the pipeline.
Pipe Brackets:
6WDQGDUG or purpose made metal pipe brackets are normally employed. These should be of the maximum
possible bearing width and should have no sharp edges likely to cause pipe damage.
The brackets may be plastic coated but where this is not practical a layer of rubber felt , or similar soft, non
DEUDVLYHPHPEUDQHPXVWEH[HGWRWKHEHDULQJIDce prior to installation.
Pipe Supports:
UPVC pipes must be adequately supported. The following table shows the recommended support intervals
for horizontal pipes conveying water. Where liquids of greater density are being conveyed the intevals of
support should be reduced proportionately.
For vertical pipe runs, the support intervals may be increased to double those shown except in exposed situations where wind loading, etc., may dictate adherence to the intervals tabulated below.
