3PE anti-corrosion steel pipe refers to the anti-corrosion steel pipe with a three-layer structure applied sequentially on the steel pipe surface: Fusion-Bonded Epoxy (FBE), Adhesive (AD), and Polyethylene (PE), abbreviated as 3PE anti-corrosion steel pipe. Among them, the FBE layer typically has a thickness of 200-300μm, offering excellent electrical insulation and chemical stability; the intermediate AD layer serves as a bonding layer with a thickness generally ranging from 150-250μm, primarily functioning to firmly bond the FBE layer with the PE layer; the outer PE layer usually has a thickness of 2-5mm, providing good weather resistance and mechanical protection capabilities. The three-layer structure works together through chemical bonding and physical adhesion to form a stable anti-corrosion system, enabling the steel pipe to effectively resist corrosion medium erosion in complex environments.
