UPVC pipe and fitting system
- UPVC (unplasticized polyvinyl chloride) is one of the must popular thermoplastic materials used for pipe work installations.
- Light in wight UPVC has excellent resistance to chemicals
- It’s extremely smooth bore gives excellent flow characteristics without sediment or deposit
- Connections can be made by either solvent cement or rubber rings

Thermal expansion
The Thermal Coefficient of linear expansion for UPVC is 7X105 / °C. it is necessary in certain situations to make special provision for this expansion and contraction.
