PP or carbon steel or SUS304 or SUS316L.it can dischange liquid automatic with air valve and vacuum valve

After 15 years research and development, we take the carbon steel as the basic substance with the unique technology and mix PE,PP,PO and the other materials with steel (inner lining, outer lining), which make steel lining plastic not only have the mechanical strength of steel, but also the features of corrosion resistance, wear resistance, temperature resistance, pressure resistance and non-scaling.
