Hard UPVC Fittings


Hard polyvinyl chloride (UPVC) is used to produce a wide range of plastic pipes and fittings. This material is remarkably resistant to chemical erosion and has a smooth interior surface which improves water flow. UPVC has high chemical resistance across its working temperature range, with a wide range of operating pressures. Due to some features including long-term strength, high stiffness and affordability, UPVC systems are widely used in plastic fittings and pipes. It has been demonstrated that the addition of nanoparticles significantly improves the strength and stiffness of UPVC. 


  • Particularly for water supply pipes

Advantage of Using Nanotechnology

Addition of nanoparticles significantly improves both the toughness and stiffness of UPVC, while having little effect on the tensile strength. The evaluation of impact property was performed according to ISIRI 9119.

ISIRI 9119: plastics-Unplasticized poly (vinyl chloride) (PVC-U) pipe, fittings and piping system for soil and waste discharge within building structure- specifications.
