Zhoukou pe underground drinking water pipe manufacturers pe water pipe wholesale Zhoukou

Zhoukou municipal projects preferred pe water pipes biggest manufacturer, specializing in production and sales of customized pe pipe fittings, pipe fittings 8 years of production experience, 50 years of quality assurance, factory direct 13673391560 pe polyethylene pipe has a very prominent low temperature resistance PE pipes low temperature embrittlement point of -70 ℃, better than other pipes. In winter field construction PVC (PVC-U) pipes easy to rattle, my Beijing area laying PVC (PVC-U) buried Water Pilot Project is an experience summarized in subzero temperatures would not be suitable for Polyvinyl chloride (PVC-U) pipe laying construction of the. There is a clear evidence for improved toughness and low temperature impact resistance PP can be made of ethylene and propylene monomer random copolymer polypropylene (PP-R), which generally use the process route and method iPP make a mixed gas of propylene and ethylene co-polymerization to obtain a main chain randomly distributed copolymer of propylene and ethylene segments (ie, PP-R pipe material), PP-R pipe material, mostly ethylene content of about 3%. But the improved PP-R low temperature performance is still unsatisfactory, its brittle point of about -15 ℃, much higher than the brittle point temperature polyethylene pipe -70 ℃. PE (polyethylene) material because of its high strength, corrosion-resistant, non-toxic and other characteristics, are widely used to pipe manufacturing. Because it does not rust, it is an ideal alternative to ordinary iron pipe to pipe. PE pipe implementation of national standards: GB / T 13663-2000 "for water supply polyethylene (PE) pipe."
