van stone flange ring of PPH pipe.PPH/steel flange
1. PPH pipe Introduction
PPH is a β-modified PP material. PPH pipe has excellent property of chemical resistance, abrasion resistance, insulation resistance, high temperature, non-toxic, light weight, easy to transport and install. It has better property than PP pipe.
Brand:DINAI VALVE
PPH pipe and fitting is designed according to DIN8077/78 standards.
PPH pipe Features
1) health, non-toxic.
2) low temperature resistance, easy winter construction. Good impact resistance, will not happen tube rattle.
3) corrosion resistance, not scaling.
4) Sizes 20mm-500mm
5) socket fusion, butt welding connection
6) working temperature from -10℃ to 95℃.
7) pressure rate: PN10(1.0Mpa)
8) connection: socket fusion
