An emerging composite pipe and pipe, many places referred to as steel-plastic pipe. Steel refers to spiral tube, seamless tube, straight seam tube, elbow, etc.; plastic, refers to plastic, plastic in steel-plastic composite tube is generally high density polyethylene.There are many classifications of steel-plastic composite pipes.

which can be classified according to the structure of pipes steel-reinforced steel-plastic composite pipes, seamless steel-reinforced steel-plastic composite pipes, steel mesh steel-plastic composite pipes and steel mesh skeleton steel Composite pipe. At present, the most popular on the market is the steel belt reinforced steel-plastic composite pipe, which is us.

It is often said that the steel-plastic composite pressure pipe, the intermediate layer of the pipe is a steel strip layer formed by butt welding of a high carbon steel belt, and the inner and outer layers are high density polyethylene  The middle layer of the pipe is steel belt, so the pressure bearing performance of the pipe is very good. Unlike the aluminum belt, the pressure is not high, the maximum diameter of the pipe can only be 63mm, and the maximum diameter of the steel pipe can be 200mm or even larger.

Since the steel strip of the middle layer of the pipe is sealed, the steel-plastic pipe has the oxygen barrier effect and can be directly used for the direct drinking water project, and the inner and outer layers are made of plastic material, which has very good corrosion resistance. Such excellent performance makes the steel-plastic composite pipe widely used, and oil, natural gas transportation, industrial and mining pipes, drinking water pipes, drain pipes and the like can be seen in various fields.
