HDPE Gas Pipe

PE gas pipes are extruded using a special polyethylene plastic extruder with raw materials. They are often used in urban gas transmission of plastic tubing. As PE is the insert material, it can resist corrosion from a variety of chemicals, and there is no electrochemical corrosion. The HDPE gas pipe also has a high toughness, an elongation of 500 meters, and an excellent aseismic performance. These PE gas pipes have a strong resistance to cracking, and a slow or fast growth ability, based on customer requirements, in order to reduce the risk of accidents caused by cracks in the pipe.
