According to PE pipe from the pressure rating to sub divided into 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, 1.6MPa, MPa pressure units, such as the pressure is 0.6MPa 6 kg mean. According to sub-diameter PE pipe can be divided into: 20,25,32,40,50,63,75,90,110,125,160,180,200,225,250,280,315,355,400, 450 Supply PPR pipe equipment, 500,560,630,710,800,900,1000,1200 units are mm is millimeters, PE pipe diameter are mean diameter, corresponding to different levels of pressure PPR pipe equipment, pipe wall thickness will vary. PE is a polyethylene plastic plastic PPR pipe equipment, the most basic kind of plastic, plastic bags, cling film are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. Original state of HDPE milky white appearance in thin cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of living and industrial chemicals. PE pipe welding, PE pipe butt weld: This is a method Which PPR pipe equipment, the method provides the highest reliability and the range of diameters and pressure process: heating the ends of the tube, using a tool, known as "mirroring" contacting under defined pressure and temperature. Ends are quickly contact, and kept under pressure during cooling.
