3PE Pipe External Anticorrosive Production Line

This steel pipe anti-corrosion coating line is designed for factory-applied anti-corrosion coating of steel pipes of various diameters. It is widely used in a wide range of engineering projects, especially for heating, gas and oil transmission. The production line supports FBE, 2L FBE, 2L PE, 2L PP and 3L PE anti-corrosion coating processes. The 3L PE coating structure comprises a bottom FBE layer, an intermediate adhesive layer and an outer polyethylene layer.
