Welded square pipe & tube is cold bent, processed and molded with stainless steel strip or coil as its base material. Then it will be subjected to high frequency welding to become profile steel with the section in square shape. It features good comprehensive mechanical properties, hot and cold workability, corrosion resistance and low temperature plasticity. Seamless square pipe & tube is cold drawn and extruded into the square shape, totally different from welded square shape. Stainless steel seamless square pipe & tube is extensively used for fluid transportation.
