What is the difference between the characteristics of PE, PP and PVC pipes? China's plastic pipes have initially formed a plastic pipe industry based on polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes and polypropylene (PP-R) pipes. . Among them, polyethylene (PE) pipes are widely used in building water supply, building drainage, underground drainage pipes, building heating, gas transmission, gas transmission, gas transmission pipes, electrical and telecommunication protection casings, industrial pipes, agricultural pipes, etc. Mainly used for urban water supply, urban gas supply and farmland irrigation. PP tube is non-toxic, hygienic, high temperature resistant and recyclable. It is mainly used for indoor and outdoor cold and hot water supply systems, and is also widely used in heating systems. PVC-U pipeline has strong anti-corrosion ability, easy to bond, low price and hard texture. However, due to the exudation of PVC-U monomers and additives, it is only suitable for water supply systems where the delivery temperature does not exceed 45 ° C. Plastic pipes are used to transport drinking water, wastewater, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air, and vacuum systems.
