PE polyethylene PE is polyethylene plastic, which is a series of resins produced by various processes, with various structures and characteristics and various uses. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes, which are divided into SDR11 and SDR17.6 series according to wall thickness. The former is suitable for transporting gaseous artificial gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. Compared with steel pipes, the construction process is simple and has a certain degree of flexibility. What's more, it does not need to be used for anti-corrosion treatment, which will save a lot of processes. The disadvantage is that the equipment is not as good as steel pipes. During construction, special attention should be paid to the safe distance of thermal heating, and it cannot be exposed to sunlight in the air, and it is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.
