PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. The earliest plastic pipe developed and applied.
PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture, but due to the exudation of PVC-U monomer and additives, it is only suitable for water supply systems with a conveying temperature not exceeding 45 °C. Plastic pipes are used in drainage, wastewater, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum system applications.
PVC-O pipe, the Chinese name is biaxially oriented polyvinyl chloride, is the latest evolution of PVC pipe, the pipe manufactured by special orientation processing technology, the PVC-U pipe produced by extrusion method is subjected to axial stretching and diameter The long-chain PVC molecules in the pipe are regularly arranged in the biaxial direction, and a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance is obtained.
