PE pipe characteristics: 

 PE pipe is a special polyethylene as raw material by the plastic extrusion machine first extrusion molding, used in urban water supply networks, irrigation water diversion project, the waste treatment plant, sewage collection pipeline engineering and agricultural plastic pipe of the spray irrigation project. PE pipe PE pipe using hot melt, hot melt connection of power to achieve the integration of the interface with the pipe, and to effectively resist the pressure inside the ring to the impact of stress and axial stress, and PE pipes do not add to the heavy metal salt stabilizer , non-toxic material, does not scale, does not breed bacteria to avoid the secondary pollution of drinking water. 

 The technical requirements of the PE water pipe:
