PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) Rigid PVC pipe, which is extruded by hot pressing method after the cooperation of PVC resin with stabilizer and lubricant, was the first plastic pipe to be developed and applied.

PVC-U pipe is highly resistant to corrosion, easy to bond, low in price, and hard in texture, but due to PVC-U monomer and additive exudation, it is only suitable for use in water supply systems where the conveying temperature does not exceed 45°C. Plastic pipes are used in drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems applications.

PVC-O pipe, the latest evolutionary form of PVC pipe, is manufactured by a special orientation processing process. PVC-U pipe produced by extrusion method is axially stretched and radially stretched so that the long chain molecules of PVC in the pipe are arranged in a biaxially regular manner to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.

Advantages of PVC pipes

  • High mechanical strength

  • Small fluid resistance

  • Excellent corrosion resistance

  • Good water tightness

  • Anti-bite

  • Low cost

  • Long service life

  • Recyclable,environmentally friendly

  • Light weight

  • Easy construction and installation

PUHUI provide the PVC pipes from DN 16mm to 710mm.
