What material is PE water supply fittings made of

PE water supply pipe fittings due to high compressive strength, corrosion resistance and other characteristics, welding pipe fittings are now widely used in water supply and drainage industry applications, but also gradually replace the general iron and cement drainage pipe application, then PE water supply pipe is made of what material, why can be widely used. First, high density polyethylene, butadiene copolymer alone under the condition of bottom pressure, so it is also called bottom pressure polyethylene; High pressure polyethylene raw materials have very good compressive strength properties, so pe water supply pipes are widely used in the field of pressure pipes. Second, low density polyethylene, butadiene copolymer alone in high pressure conditions, so it is also known as high pressure polyethylene, the compressive strength of the pipe is low, so only for low pressure small diameter pipe, PE siphon parts are often made into fan coil for rural water and some non-permanent application sites. PE water pipe material polyethylene has high quality corrosion resistance, good environmental health performance and long service life; Exceptional flexibility and excellent scratch resistance; It has very prominent cold resistance and excellent rapid cracking to improve impact toughness. PE water pipe materials are also good and bad points, so when buying goods, we must pay attention to the quality of its materials have a certain grasp, so as to ensure the quality of goods and its application of the actual effect.
