A Brief Discussion on 3PE-Coated Steel Pipes
2022-05-07
3PE steel pipe It is a new type of anti-corrosion steel pipe, because… 3PE steel pipe With its affordable price and reliable quality, it has found widespread application in the transportation of natural gas and petroleum pipelines. It also exhibits excellent resistance to corrosion and to both acids and alkalis, significantly extending the service life of the steel pipes used in such applications.
3PE steel pipe The structure consists of three layers: the first is an epoxy powder coating, the second is an adhesive, and the third is polyethylene. These three materials are seamlessly integrated and firmly bonded to the steel pipe, forming an outstanding anti-corrosion barrier.
3PE steel pipe The base materials include spiral welded steel pipes, seamless steel pipes, and straight-seam steel pipes. Three-layer polyethylene (3PE) anti-corrosion coating is widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability, and mechanical properties. 3PE steel pipe The anti-corrosion coating is critical to the service life of underground pipelines. Some pipelines made of the same material, when buried for decades, remain free from corrosion. However, due to the use of different external protective coatings, leaks may occur after a few years.
