Plastic Coated Spiral Steel Pipe
Plastic-coated composite steel pipe is a steel-plastic composite pipe composed of a layer of organic matter 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, easy connection, and water shock resistance of steel pipes, but also overcomes the shortcomings of steel pipes such as easy corrosion, pollution, scaling, low strength of plastic pipes, and poor fire performance. The design life can reach 50 years. The main disadvantage is that it is not allowed to bend during installation, and when performing operations such as thermal processing and electric welding and cutting, the cutting surface should be painted with non-toxic room temperature curing glue provided by the manufacturer.
