PE pipe for water supply is the traditional steel pipe, PVC water pipe replacement. Water supply must withstand a certain pressure, usually opt for large molecular weight, good mechanical properties of PE resins, such as HDPE resins. LDPE resin is low tensile strength, pressure difference, poor rigidity, poor dimensional stability during molding, and the connection difficult Qingdao PPR pipe production line, suitable as water pressure tube material. But because of its high health indicators PPR pipe production line, PE especially HDPE resin production of drinking water has become a common pipe materials. HDPE resin melt viscosity is small, good fluidity, easy processing, and therefore their choice is also a wide range of melt index, usually between MI 0.3-3g / 10min. 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, 450,500,560,630,710,800,900,1000,1200 PPR pipe production line price, which is the unit is mm mm, PE pipe diameter are mean diameter, wall thickness corresponding to different levels of pressure, pipe also it varies. PPR pipe production lines, PPR pipe production line, the days of the letter provided by the Qingdao-day letter Thai Thai Plastic Machinery Co., Ltd.
