Description
PP is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP don’t have the problem of environmental stress cracking. Moreover, it could offer significant resistance to any chemical or acid. PP pipe is a kind of plastic pp made of copolymerized polypropylene resin and extruded. It has light weight, good chemical stability, heat resistance, insulation, high mechanical strength and non-toxic.At present, the PP pipe connection mode widely used in construction is:1. welding sleeve socket welding method 2End edge welding method. 3. dissimilar material take over: used in petroleum, chemical, chlorine alkali, dye, agriculture, food, medicine, light industry, metallurgy, waste water treatment, water supply and drainage, etc.
