Inside and outside the plastic steel plastic composite pipe consists of a plastic layer, adhesive layer, steel pipe layer, an adhesive layer, a plastic layer, an adhesive layer is positioned in the plastic layer and the steel layer between the technology out of the ordinary, plastic and steel organically, is connected to the gap. Its biggest characteristic is to overcome the disadvantage that the steel pipe is not resistant to corrosion and the corrosion resistance of the plastic pipe is not pressure. Compared with various kinds of steel pipes, plastic pipes, aluminum-plastic composite pipes, stainless steel pipes and copper pipes, it has obvious advantages in hygienic indexes, physical and chemical properties and cost. It has corrosion resistance, aging resistance, no rust, tasteless, non-toxic, smooth wall, high temperature resistance, high pressure resistance, light weight, heat insulation and so on, to solve the industry pipeline corrosion, aging problems and loss of pipeline water supply and drainage engineering, gas engineering and chemical industry is the most ideal. |
