PE (polyethylene) is one of the most basic plastic. Due to its high strength, high temperature resistant, anti-corrosion, non-toxic, wear resistance and other characteristics, PE material is widely used in water supply and drainage manufacturing. According to the wall thickness, it can be divided into SDR11 and SDR17.6 series. Compared with steel pipe, PE pipe construction process is simpler and has certain flexibility. More importantly, it will save a lot of processes by leaving out the antiseptic treatment.
