Stainless steel tube with the social and economic development, its application has also been more widespread. In various fields will bring a new change. 
 The theoretical weight of stainless steel: W = diameter - stainless steel pipe wall thickness x wall thickness x0.02491 the record count means diameter - wall thickness x wall thickness x0.02491. 
 Since the beginning of this century the invention of stainless steel, stainless steel put the image of modern materials and construction applications rolled into one excellent reputation, its competitors envy. Stainless steel does not produce corrosion, pitting, corrosion or wear. Stainless steel or metal materials used in construction materials in one of the highest intensity. Because stainless steel has good corrosion resistance, so it can maintain a permanent structural component engineering design integrity. Chromium stainless steel is also set high mechanical strength and extension in one, easy-to-parts manufacturing to meet the architects and structural design personnel.
