Plastic-lined steel pipe, which combines the characteristics of various pipelines, both have high strength, high extensibility, low temperature brittleness, and low expansion coefficient of steel tube, and corrosion resistance, abrasion resistance, small fluid resistance of plastic pipe. It is a new type of water supply and drainage pipeline, anticorrosive and green pipe, widely used by domestic industries.

We developed plastic-lined steel pipe production line, using the production processes of composite extrusion lining plastic skin tube, mechanical piercing tube and multiple-stage high frequency local heating, with the advantages of high degree of automation, high production and etc, also can choose the materials of outer cladding: either anticorrosive plastic or praying epoxy resin, according to the actual requirements.
