What is PE Pipe?
- Sep 19, 2018 -


PE is a polyethylene plastic, the most basic kind of plastic, plastic bags, cling film, etc. are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section. PE has excellent resistance to most living and industrial chemicals.


PE pipe welding, PE pipe butt welds, this method provides the highest reliability and diameter within the range and pressure process: the end of the heated pipe, using a tool called "contact mirroring and temperature" under the definition of "mirror ". The ends are quickly contacted and kept under pressure during the cooling process.


PE pipes are medium density polyethylene pipes and high density polyethylene pipes. According to the wall thickness, it is divided into SDR11 and SDR17.6 series. The former is suitable for conveying gaseous artificial gas, natural gas, and liquefied petroleum gas, and the latter is mainly used for conveying natural gas. Compared with steel pipes, the construction process is simple, has certain flexibility, and more importantly, it is not used for anti-corrosion treatment, which will save a lot of processes. Disadvantages are not as good as steel pipes. Special attention is paid to the safe spacing of thermal heating during construction, and it should not be exposed to the sunlight in the air, and it is sensitive to chemicals and prevents leakage of sewage pipes.
