Plastic Coated Spiral Steel Pipe
Plastic-coated composite steel pipe is a steel-plastic composite pipe consisting of a layer of organic material with a thickness of 0.5-1.0mm melted on the inner wall of the steel pipe. It not only has the advantages of high strength of steel pipe, easy to connect, water shock resistance, etc., but also overcome the steel pipe is easy to corrode, pollution, scaling, low strength of plastic pipe, poor fire performance and other shortcomings. Design life can reach 50 years. The main disadvantage is that the installation does not allow bending, and in the heat processing, welding cutting and other operations, the cutting surface should be coated with non-toxic room temperature curing adhesive provided by the manufacturer.
