SHK PPR-C PIPES & FITTINGS
Raw Material: Polypropylene Random Copolymer
SHK PPR-C Pipes and fittings are manufactured from Poly-Propylene Random Copolymer raw material which are the most efficient solution today for Hot & Cold Water Supply.
With Advantages of High Pressure Handling, Wide Temperature Operating Range and Smooth Surefaced material, Poly-Propylene Random Copolymer has become the most Recommended Pipes for Industrial as well as Domestic Usage.
Standards for SHK PPR-C Pipes & Fittings
(a) IS 15801 for PPR-C Pipe manufacturing Process
(b) DIN 8077-8078 for PPR-C Pipes General Quality Requirements and Testing
(c) DIN 16962 Pipe Joints
