PVC Pipes

PVC Pipes

PVC-U (Unplasticised polyvinyl chloride) is one of the most popular thermoplastic materials used for pipework installations. PVC-U is lightweight and has excellent resistance to chemicals and abrasion, is tasteless and odourless making it ideal for use with potable water systems and most food products as its extremely smooth bore gives excellent flow characteristics without sediment or deposit. PVC-U is resistant to most solutions of acids, alkalis, salts and solvents. Connections can be made by either solvent cement or BSP threaded fittings.

WRAS Approval
PVC-U is approved by the Water Research Advisory Scheme (WRAS) for use with potable water.

PVC-U pipe is manufactured in accordance with EN1452-2 PVC-U fittings are manufactured in accordance with EN1452-3 / BS4346 Part 1 PVC-U threaded fittings are manufactured in accordance with BS21, DIN2999, ISO7

Chemical Resistance
PVC-U is resistant to most solutions of
Water soluable solvents

PVC-U is not resistant to
Aromatic hydrocarbons
Chlorinated hydrocarbons

PVC-U System Pressure/Temperature Relationship
Pressure ratings for plastic pipework systems are always quoted at 20°C, it is a fundamental principle of such systems that if the temperature is increased then the pressure rating must be reduced.  PVC-U systems should never be used for temperatures in excess of 60°C.
