Plastic-steel-plastic composite pressure pipe

PSP steel plastic composite pressure pipe is formed by rolling steel strip and continuous argon arc butt welding. It adopts the composite structure of extruded inner and outer composite plastic layer and reinforced welded steel pipe in the middle. The utility model not only overcomes the problems of easy corrosion, easy scaling and unsanitary of the steel pipe, but also solves the defects of low strength, easy deformation and short service life of the plastic pipe. Combining the advantages of steel pipe and plastic pipe, it has the advantages of high strength, good rigidity, good oxygen isolation, corrosion resistance, scaling resistance, good sanitary performance, easy buried detection and so on.
