PVC pipe (PVC-U pipe) The rigid PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricant, etc., and is extruded by hot pressing. It is the first plastic pipe that has been developed and applied. PVC-U pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the oozing of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45 °C. Plastic pipes are used to transport drinking water, wastewater, chemicals, heating fluids and coolants, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems.
