Plastic-coated composite steel pipe is based on a welded steel pipe and seamless steel pipe, and the inner and outer walls are coated with epoxy resin or polyethylene powder. It is an anti-corrosive, corrosion-resistant, non-toxic, and non-radiation green environmental protection pipe, which is used in various fluid transportation. The base pipe is a longitudinally welded steel pipe and shall meet the requirements of GB/T3091-2008 for the base pipe; if the base pipe is a seamless steel pipe, it shall meet the requirements of GB/T8163-2008 for the base pipe; the base pipe is a spiral submerged arc welded steel pipe. It should meet the requirements of SY/T5037-2000 for the base pipe.
1.The product has the following advantages:
2. It retains the rigidity and strength of traditional metal pipes, which is far better than plastic pipes and aluminum-plastic pipes;
3.It has the characteristics of the smooth inner wall, low friction resistance, and no scaling, and the outer wall is more beautiful and luxurious;
4.Lightweight, good toughness, impact resistance, high compressive strength; applicable temperature is wider -30℃～100℃;
5.The connection with the pipe fittings can be made of stranded wire, socket, flange, groove, welding, etc., various methods, saving labor and effort;
6.The thermal expansion coefficient difference in the connection part in the pipe fitting is small, which is safer and more reliable;
7.Reasonable price-performance ratio, low overall cost, and more economical than copper pipes and stainless steel pipes. The steel strip in the middle of the perforated steel strip has been punched with a lot of holes, so that the inner and outer layers of PE are organically combined, thus solving the composite problem of steel and plastic, but at the expense of the oxygen barrier performance of the steel-plastic pipe. The presence of the mesh on the steel belt greatly reduces the compressive strength of this type of steel-plastic pipe. Under high-pressure working conditions, the pipe is prone to local bursting.
