Technique	steel plastic composite

omprises of plastic layer,the binding layer between the plastic layer and steel tube layer binds these two layers in a seamless connection through technique.The biggest advantage is that it solves the problem of insufficient corrosion resistance in the pressure steel tube as well as insufficient pressure resistance in the corrosion resistance plastic tube.Compared with other steel tubes, plastic tubes, composite aluminum plastic tubes, stainless steel tubes and copper tubes, the new tube is more superior in sanitary criteria, physical/chemical properties and cost, it features corrosion resistance,aging resistance, rust-free,odor-free,toxic-free,smooth internal wall, high temperature and pressure resistance,insulation and other properties, which eliminates troubles like pipe corrosion and aging and related losses in the industries, and is the ideal pipe for water suppy and drainage, gas supply and chemical engineering.
 The composite metal plastic tube has obtained certification from concerned state industries and meets the engineering construction standard of the state engineering construction standardization committee as well as the administrtive provisions for sanitation supervision of potable water. Properties:

ND:6-315mm
 Working Pressure:-0.08-10Mpa
 Corrosion resistance:resistant to 50% sodium hydroxide,38% hydrochloric acid,50% sulfuric acid.
 Weight:50% of galvanizes tube
 Leakage:no leakage at 3.2Mpa
 Flow resistance:50% of metal tube
