INTRODUCTION
PVC pressure pipes are manufactured from unplasticized polyvinyl chloride polymer (a thermoplastic material) using the
extrusion process. PVC (also known as uPVC and PVC-U) pipes were introduced to Sri Lanka in the late 1950s by S-lon and are
now widely accepted for use in water supply, irrigation and sewerage rising mains.

The good flow characteristics are the result of the smooth bore and good a resistance to abrasion. It is light in weight, easy to join
together, making uPVC a good alternative to the more traditional materials. Their high strength to weight ratio together with
exceptional resistance to corrosion or chemical attack makes these pipes ideal for major infrastructure applications.

MATERIALS
S-lon uPVC is stabilized with compounds conforming to the International safety levels (Non Lead) for vinyl chloride monomer
(VCM) and the WRAS requirements for use with potable water.

COLOUR
uPVC products are recognized by their light grey colour.

CHEMICAL RESISTANCE
The chemical resistance properties of uPVC is excellent: it is resistant to most solutions of acids, alkalis and salts and to solvents
that can be mixed with water. uPVC is not resistant to aromatic and chlorinated hydrocarbons.

Thermal Expansion
The thermal coefficient of linear expansion for uPVC is 7.8 x 10-5m/m.°C
It is necessary in certain situations to make special provision for this expansion and contraction.
Thermal expansion of uPVC is compared with other materials, in the following chart.

STANDARDS
Individual products are in compliance with appropriate Standards:

Pipe (mm size) SLS 147:2013 , BS EN ISO 1452-2:2009

Fittings (mm size) SLS 659:2015 , BS EN ISO 1452-3:2009
Sealing Rings BS EN 681-1
Bends SLS 659:2015 , BS EN ISO 1452-3:2009

QUALITY MANAGEMENT SYSTEM

Pipes, fittings and other accessories are manufactured in an environment, which operates a Quality Assurance System assessed to
ISO 9001.

DRINKING WATER/ APPROVAL TO USE IN CONTACT

In any situation which could result in the PVC-U pipes, fittings and solvent cement coming into contact with water which is
intended for human consumption. This shall be in accordance with the requirements of BS 6920 Part 1.

WRAS-UK (Water Regulations Advisory Scheme) certified that S-lon uPVC pressure pipes are suitable for use in contact with water
intended for human consumption with regards to their effect on the quality of the water.

S-lon uPVC pipes are listed in the WRAS website under ‘Product and Material’ category.

WHY PVC FOR PRESSURE APPLICATIONS?
S-lon PVC pressure pipe systems offer many advantages when compared to traditional products, namely:

Enhanced hydraulic performance.

Durability and toughness – resistance to handling and installation damage.
Corrosion resistance – greater service life.
Lower mass – ease of handling and installation, particularly suited to labour intensive projects.
Locked-in sealing ring system – no specialist installation skills required.
Savings on installation time.
Manufactured within internationally accepted standards.
Service performance in excess of 50 years.
Highly recyclable - Waste generated during manufacturing is pulverized and reprocessed.
Unique combination of properties:
- Toughness
- Stiffness
- High tensile and hoop strength
- Excellent resistance to creep
Savings on transport cost.
Energy efficient - PVC pipe production consumes less energy during manufacturing than steel, clay or ductile iron.

SPECIFICATION FOR UNPLASTICIZED POLYVINYL CHLORIDE PIPES FOR WATER SUPPLY THROUGH BURIED AND ABOVE
GROUND DRAINAGE AND SEWERAGE UNDER PRESSURE (Third Revision)

DIAMETER
PVC pressure pipes are specified by their nominal size (i.e. outside diameter) in millimeters. For design purposes, reference should be made to
tables detailing the internal diameters as calculated from the average wall thicknesses of the particular pressure class of pipe.

PRESSURE CLASS
A range of pressure “classes” is available in each size. These classes are based on the pipe’s recommended maximum working pressure in bar.
For example, a class PNT 14 pipe has a recommended maximum working pressure of 14 bar, or 14 metres head at a temperature of 300C.

S-lon unplasticized PVC (PVC-U) pressure pipe is a tried and tested system demonstrating a long track record in the water reticulation sector.
S-lon pressure pipes are manufactured to the SLS 147 specification, incorporating the traditional design stresses of 10 and 12.5 MPa. The
product is ideally suited to applications in both pumping and gravity designs.

S-lon uPVC Pipes For Drainage Application

S-lon non pressure uPVC pipes comply with the requirements of SLS 1286 (ISO 4435 ) and are SLS marked in accordance with the
SLSI certification scheme. S-lon pipes are supplied in grey colour with plain ended, solvent socketed and rubber ring joints and standard length
6 metres.

SLS 1286 standard specifies the requirements for uPVC pipes, intended for use for non-pressure underground drainage and sewerage
for the conveyance of soil and waste water discharge of domestic and industrial origin, as well as surface water.

S-lon Sewerage and Waste Water Pipes & Fittings

S-lon Soil, Waste and Vent pipes and fittings are manufactured from UV stabilized uPVC which is tough and resilient.
uPVC, the major material component is self-extinguishing and will not support combustion. Furthermore, uPVC is
unaffected by coastal or industrial atmospheres, or by the use of domestic cleaning agents. S-lon soil and waste uPVC pipes
and fittings comply with the requirements of SLS 1325 (ISO 3633). Pipes are in Grey colour and supplied in 6m lengths.

SLS 1325 Standard specifies the requirements for uPVC pipes and fittings for soil and waste discharge (low and high
temperature) inside buildings, as well as the system itself.
