Steel plastic composite pipe is a new type of anticorrosion pipe, it takes advanced thermal rotational molding process, Integrated steel and plastic, pipe fittings (including elbow, tee, cross, size) are all made of whole steel shell, plastic liner pressure injection molding. It has both the mechanical strength properties of steel and the advantages of steel plastic pipe with Corrosion resistance, no scaling, not easy to grow microorganisms, can guarantee the purity of medium, etc. Steel plastic composite pipe is the optimal corrosion product to replace rubber, glass-lined, fiberglass, is the ideal anticorrosive pipe to transport acid, alkali, salt, gas, pulp, and so on. The characteristics of steel plastic anticorrosive pipe: 1, Excellent physical properties 2, Excellent corrosion resistance 3, The same mechanical strength with steel 4, Health non-toxic, non-fouling, non-breeding microorganisms, fluid quality assurance 5, Chemical resistance, corrosion resistance, soil and marine life, resistance to cathodic stripping 6, Installation process maturity, convenient 7, Good weather resistance, for desert, salt and other harsh environments 8, Smooth wall, improve transport efficiency, long service life
