What is the plastic steel composite pipe?
The plastic lining composite pipe in pipe wall, according to the requirements of the transmission medium with polyethylene (PE), heat-resistant polyethylene (PE-RT) crosslinked polyethylene (PE-X) thermoplastic plastic tube, therefore has superiority of steel pipe and plastic pipe.Plastic coating steel pipe to pipe material, plastic powder coating material, the surface coated with a layer of plastic melt layer, the outer surface of the molten coating on a plastic layer or other material coating of steel plastic composite products in the. According to the internal coating material, the material is divided into two kinds, one is polyethylene coated steel pipe. The other is epoxy resin coated steel pipe.
Steel plastic composite pipe has been relatively mature now, in many fields has been widely used in petroleum, chemical, construction, shipbuilding, electric power and communications, the underground gas pipeline, is currently the preferred alternative to traditional galvanized pipe, known as the green environmental protection pipe.
Steel plastic composite pipe is a new type of pipe material developed in recent years, the seamless steel pipe, welded steel pipe, galvanized steel pipe as the substrate, with various types of plastic (such as epoxy resin, polyethylene etc.) formed by the compound. According to the process of plastic and the substrate can be divided into plastic lining composite steel pipe and plastic composite pipe two.
