Advantages of PE water supply pipe
China's plastic pipeline has developed rapidly. At present, a plastic pipe industry mainly composed of polyvinyl chloride ( PVC-U) pipe, polyethylene (PE) pipe, and polypropylene (PP-R) pipe has been formed . Among them, polyethylene pipe is widely used in building water supply, building drainage and other uses due to its unique advantages.
是 polyethylene的简称，是乙烯经聚合制得的一种热塑性树脂。 PE is the abbreviation of polyethylene, which is a thermoplastic resin made by the polymerization of ethylene. 没有明显异味，安全 无毒 ,手感似蜡,具有优良的耐低温性能，化学稳定性好,能耐大多数酸碱的侵蚀，常温下不溶于一般溶剂,吸水性小,电绝缘性能优良。 Polyethylene has no obvious odor, is safe and non-toxic , and feels like wax. It has excellent low temperature resistance, good chemical stability, resistance to most acids and alkalis, insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation properties.
Compared with traditional metal water supply pipes, PE water supply pipes will not rust, have good corrosion resistance, sanitary performance and extremely long service life. The service life of PE water supply pipes is more than 50 years, which is an international standard Confirmed and tested in practice.
独特的柔韧性和 优秀 的耐刮痕的能力 ，良好的柔韧性 使 PE给水管材 可以盘卷，避免了大量的接头和管件。 PE water supply pipe has unique flexibility and excellent scratch resistance . Good flexibility allows PE water supply pipe to be coiled, avoiding a large number of joints and fittings. 埋地管是属于 “柔性管”， 在 强度和刚性方面 当然 不及水泥管及金属管道， 但是 在正确设计和铺设施工下 PE给水管材 是和周围土壤共同 负载 的。 PE buried pipe is a "flexible pipe". Of course, it is inferior to cement pipes and metal pipes in terms of strength and rigidity . However, under the correct design and laying of PE pipes , PE pipes are co- loaded with the surrounding soil . PE给水管材完全不需要太高的刚性强度就足以负担给排水任务 。 Therefore, PE water supply pipes do not need too high rigidity at all, which is enough to support the water supply and drainage tasks .
PE给水管材是一种高韧性材料，聚乙烯的压力松弛特性可有效地通过形变而消耗应力，其实际轴向应力水平远比理论计算值低，而且其断裂伸长率一般都大于500%，弯曲半径可以小到管直径的20～25倍，这些特点使其成为抵御地震、地基沉降以及温差伸缩的最为优秀的管道。 At the same time, PE water supply pipe is a high toughness material. The pressure relaxation characteristics of polyethylene can effectively consume stress through deformation. Its actual axial stress level is much lower than the theoretical calculation value, and its elongation at break is generally greater than 500%. The bending radius can be as small as 20 to 25 times the diameter of the pipe. These characteristics make it the most excellent pipeline to resist earthquakes, foundation settlement, and temperature differential expansion. For example, during the 1995 Kobe earthquake in Japan, PE water pipes and gas pipes were the only pipe systems that were spared.
It is no doubt that PE water pipe is a very efficient and economical choice to solve construction problems.
