3PE anti-corrosion steel pipe is a commonly used anti-corrosion pipeline, consisting of three layers of polyethylene, namely epoxy powder layer (FBE), adhesive layer, and polyethylene layer. The epoxy powder layer usually has a thickness of over 100 microns, providing good adhesion and corrosion resistance. The thickness of the adhesive layer is between 170 and 250 microns, ensuring a tight bonding of the three-layer structure.
