3PE anti-corrosion steel pipe is a steel pipe with a three-layer polyethylene (3PE) coating for outer wall corrosion protection. Its structure from inside to outside is: bottom layer epoxy powder (FBE, thickness>100μm), middle layer copolymer adhesive (AD, thickness 170-250μm), surface layer high-density polyethylene (PE, thickness 1.8-3.7mm). This structure combines the strong adhesion of epoxy resin and the corrosion resistance of polyethylene, and is one of the globally recognized pipeline anti-corrosion solutions.
3PE anti-corrosion steel pipe is the world advanced anti-corrosion technology. 3PE coating combines the excellent porperties of epoxy coating and extrusion coating of polyethylene in two. The interface properties of epoxy coatings and chemical resistance, the mechanical protection characteristics of extruded polyethylene coating combine to significantly improve the total performance of 3PE. Therefore, as buried pipelines external coating, 3PE have the most competitive advantages than other type of external coatng.
