⑴ reliable connection: the electrical connection between the hot-melt polyethylene pipe systems, the joint strength is higher than the pipe body strength. ⑵ low-temperature impact resistance: Low temperature brittleness of polyethylene is very low, can be safely used within a temperature range of -60-60 ℃. Construction in winter, due to material impact resistance, and does not occur tube embrittlement. Landscaping needs a lot of water pipes, PE pipes and low cost, it is worth promoting. 7) Municipal Trenchless Engineering: With the current development of the city, trenchless technology is widely used in the construction, while the plant commonly used in trenchless pipe jacking (drag pipe pe pipe, pulling pipe) is currently More popular with PE pipe, that its toughness and price advantage pe water pipe installed in the field of trenchless will have greater development. 8) Wastewater Treatment: There are many in the construction of a sewage treatment plant, in addition to cement pipe and HDPE double wall corrugated pipe PE pipe CBMI also be applied outside pe pipe, in actual construction, PE pipes with diameter pipe flow than other Guangdong pe water supply, while in complex environments such as turning, crossing and other construction, its convenience is more prominent. 9) Power threading: Due to the superior performance of PE pipe insulation resistance and, together with its own good compressive strength and pulled force, present in many power threading construction, often used [1]. Qingdao pe pipe, Xiong Wang Thai (certified), Tanggu pe water supply provided by Xiong Wang Thai Plastic Products Factory. Xiong Wang Thai Plastic Products Factory (www.wangtai668.com) Hebei Baoding, UPVC pipe leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
