 Introduction of Plastic Lined Pipe

Plastic lined pipe is a kind of steel pipe which lined the quality plastic against the inner wall of the steel pipe. By the ordinary steel material as the steel pipe, and excellent plastic with abrasive resistance, anticorrosion, heat-resistance and so on as a lining layer, we combine the characteristics of metal and plastic together, into the characteristics with high strength, high abrasive resistance, high anticorrosion and high heat-resistance. It has both the mechanical properties of steel pipe and the characteristics of anticorrosion, scale formation resistance of plastic pipe. Plastic lined pipe is the perfect pipeline to carry sour, alkali, salt, corrosive gas and other media. Plastic lined pipe with lined food-grade PP can be used in food, medicine and drinking water industry. Usually plastic lined pipe has PP lined pipe(GSF.PP), PVC lined pipe(GSF.PVC), PE lined pipe(GSF.PE), PO lined pipe(GSF.PO), PTFE lined pipe(GSF.F4) and so on.
Plastic lined pipe is a kind of composite pipe with many kinds of characters of polymer and steel pipe. It not only keeps the intensity and traditional connect methods of steel pipe, but also fully shows the characteristics of corrosion resistance, aging resistance, high wear resistance, stainlessness, non-toxicity, smooth inside wall and so on after different performance evolution of plastic materials. Plastic lined pipe reaches the national sanitation standard after changing performance, and it is recommended in the civilian construction, urban water supply and discharge. It is the alternative products of industrial pipeline that used in the oil transportation, chemical industry, electric power, coal mine, steamer, dock and so on.
