An emerging composite pipe material, referred to as steel-plastic pipe. There are many classifications of steel-plastic composite pipes, which can be classified according to the structure of the pipe: steel belt reinforced steel-plastic composite pipe, seamless steel pipe reinforced steel-plastic composite pipe, hole mesh steel belt steel-plastic composite pipe and steel mesh skeleton steel-plastic composite pipe.
At present, the most popular steel-plastic composite pressure tube on the market. The middle layer of the pipe is a steel belt layer formed by butt welding of high carbon steel belt crimping, and the inner and outer layers are high density polyethylene (HDPE). The middle layer of this kind of pipe is steel belt, so the pressure performance of the pipe is very good. Unlike aluminum belt, the maximum diameter of steel-plastic pipe can be 200mm or even larger; because the steel belt of the middle layer of the pipe is sealed, This kind of steel-plastic pipe also has oxygen-blocking effect and can be used directly in direct drinking water projects, while the inner and outer layers are made of plastic material, which has very good corrosion resistance. The difference between plastic-lined steel pipes and steel-plastic composite pipes is their toxicity, use environment and price.
