Three layer polyethylene anticorrosion is one of the main technical system of buried pipeline corrosion protection at home and abroad. It has good corrosion resistance, low water absorption and high mechanical strength. It has been used more and more widely in the field of buried water conveyance, gas transmission and pipeline transportation in recent years.

China has not yet formulated the 3PP coating industry standards, the processing of 3PP anti-corrosion pipeline in general use Germany DIN30678 "steel pipe polypropylene coating" standard. The 3PP coating is mainly used for pipeline coating anticorrosion pipeline high temperature medium and desert regions as the surface temperature is higher, the sunshine time longer, so the surface temperature is higher, as long buried water and gas and oil pipeline has been more and more widely used.
