3PE steel pipe
3PE steel pipe has been widely used in the oil pipeline industry, and its base materials include spiral steel pipe, straight seam steel pipe and seamless steel pipe. 3PE steel pipe-Anti-corrosion layer is very important for the life of buried pipelines, because they use different external anti-corrosion layers, so some pipes of the same material are buried underground, some leak in a few years, and some dozens Years will not corrode. The three-layer polyethylene (3PE) anti-corrosion coating has good water vapor permeability, corrosion resistance and mechanical properties.
The middle layer of the 3PE steel pipe is a copolymerized adhesive with functional groups of branch structures. The coating of the 3PE steel pipe is that the surface of the steel pipe and the bottom layer are in contact with epoxy powder anti-corrosion coating, and the surface layer of the 3PE steel pipe is high-density polyethylene anti-corrosion coating. . 3PE steel pipe coating is a new type of anti-corrosion steel pipe coating produced by ingeniously combining 2PE anti-corrosion layer and epoxy powder anti-corrosion steel pipe coating (FBE), that is (three-layer polyethylene anti-corrosion coating).
