3pe anti-corrosion steel pipeline is a relatively advanced anti-corrosion technology in recent years. Its full name is Molten Epoxy/Extruded Polyethylene Structural Protective Layer. The 3PE anti-corrosion steel pipe structure consists of the following three layers: the bottom layer is molten epoxy

During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and the surface has no scratches. The processed spiral steel pipe has more flexibility in the diameter and wall thickness size range, especially in the production of high steel g
