STRUCTURE DIAGRAM：
1、Polypropylene with dye master of high stability to UV rays and solidity to heat
2、Heterophasic block polypropylene(PP-B) for exceptional mechanical properties even athigh temperature
3、Lock the pipe
Working Pressures：
Allows the maximum working pressure(PN-PFA")OF 16 bar(UNl 9561-2)for diameters from 16 to 63 and PN 10 for diameters from 75 to 110, at the temperature of 20℃ . Maximum allowable working pressures related to the duration of pressure and temperature.Factory direct sales are fast and direct, with long wear-resistant life, no need for hot-melt, precision forging, through the team's exquisite craftsmanship, high pressure resistance, strong and durable.
