Lining plastic pipe

Lining plastic pipe

Product description

  Steel-plastic composite pipe is made of high quality steel tube as the base tube, and has excellent chemical stability, corrosion resistance, heat resistance of polyethylene (PE) and polypropylene (PP, PO) as the layer (lining). Through the exquisite multi process, the thermoplastic engineering plastics were transformed from granulated to liquid state, formed uniform, dense and smooth lining layer, and the layer the base pipe were in one under the action of centrifugal force. The steel-plastic composite pipe has the characteristics of corrosion resistance, low temperature resistance, high compression strength, low running resistance, anti-ultraviolet, electrical insulation and so on.
  The product is highly stable,non-toxic, tasteless, healthy, safe, light as well as convenient to connect. This anti-corrosion pipe is an ideal item in the profession utilization of electric power, environmental protection, chemical industry, metallurgy, coal, paper making, foodstuffs etc.
