Polyethylene pipe performance advantages: ultra high molecular weight polyethylene pipe tensile yield strength and high tensile breaking strength, heat distortion temperature ten degrees higher than normal, Guangdong polyethylene plastic water pipe, and cold brittle temperature is almost no limit Jilin poly vinyl water pipes, in addition to 100% elongation, therefore, be in a wide temperature range polyethylene water supply pipes, tubes withstand greater stress, absorb impact load and shutting down the water pressure fluctuations occur. Polyethylene pipe performance advantages: ultra high molecular weight polyethylene pipe price is more moderate. Medium diameter, medium and low-pressure pipelines total project cost is even lower than the seamless Shaanxi polyethylene water pipes, even lower than the composite tube and alloy pipes, but life is higher than six times more than steel, composite pipe more than 4 times, very significant economic benefits.
