Polyethylene pipe performance advantages: ultra-high molecular weight polyethylene pipe friction coefficient is only 1/6 of the new steel pipe, 1/5 Shanxi ordinary polyethylene ultrahigh molecular weight polyethylene pipe, ultra-high molecular weight polyethylene rubber pipes 1/20 polypropylene 1/2. And ultra-high wear resistance and non-stick, anti-corrosion and can always maintain a smooth wall flow, pipe flow capacity is generally higher than 50%, long-term low-voltage transmission system flow status. Polyethylene pipe, also known as high-density polyethylene. PE pipe extrusion technology: in the early stages of development of plastic pipe, polyethylene pipe pressure is much smaller than PVC, high-performance, high-strength polyethylene pipe. HDPE With the emergence of new materials, new technologies, this difference in cost (weight) on the occurrence of a significant change, with the second generation of polyethylene pipe material (equivalent to PE80) and the second generation of polyethylene pipe materials (quite in PE100) appears, in the same grade and the same pressure diameter 200 conditions, weight of polyethylene pipes of the same length but 93% UPVC pipe weight.
