High Speed Three Layer PE System for Buried Pipeline

This steel pipe anti-corrosion coating line is designed for factory coating of steel pipes with various diameters. It is widely deployed in engineering projects, mainly for heating, gas and oil transmission. The unit supports FBE, 2L FBE, 2L PE, 2L PP and 3L PE anti-corrosion coating processes. The 3L PE coating consists of a base FBE layer, an intermediate adhesive layer and an outer polyethylene layer.
