Is there any difference between PSP steel plastic composite pipe and plastic steel composite pipe?
PSP is also known as the steel plastic composite pipe steel skeleton plastic composite pipe, steel plastic composite pipe is a plastic pipe lining pipe in pipe inside the living cell using the ordinary plastic pipe and common steel pipe, steel plastic composite pipe is also useful
The production process of steel band reinforced plastic steel composite pipe is quite complicated. The steel strip is different from the aluminum strip, and it has almost no flexibility, so the forming process of the steel belt is very demanding. Secondly, the steel belt is usually thicker than the aluminum belt, and the lap welding process can not be used. Only the butt welding process with high accuracy is adopted.
The plastic pipe has the characteristics of high pressure and strong impact resistance; the inner and outer layer of plastic to corrosion protection with smooth wall, chemical corrosion resistance, no pollution, small fluid resistance, no fouling, not the breeding of microorganisms, the advantages of fluid from pollution two, service life of up to 50 years. The pipes are easy to overcome the steel corrosion, pollution, heavy, short service life and the existence of low strength, plastic pipe expansion volume defects and easy deformation, and has the common advantages of steel and plastic pipe, such as oxygen is good, high rigidity and high strength, easy to detect buried pipe etc..
PSP steel plastic composite pressure pipe is a new type of pipe developed in recent years in our country. The steel plastic composite pressure pipe is a new type of composite pipe made of metal and plastic. The welded steel pipe is used as the middle layer, the inner and outer layers are polyethylene plastics, and the special hot melt adhesive is used to form a pipe through the extrusion forming method.
