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. Our products not only use excellent materials, but also add anti-aging and anti-ultraviolet ingredients, and the service life is many times that of other products.No leakage is more assured, the material is selected, and the quality is focused.
