Stainless Steel Large Diameter Pipe

Stainless steel seamless and welded pipes with an outer diameter greater than 8″(219.1mm) are generally referred to as large-diameter pipes. Both of them have the specified features of stainless steel such as excellent corrosion resistance and good mechanical properties, which have been mainly used in machinery, transportation, aviation, construction and other fields. The size of large diameter seamless stainless steel is 8″ to 30″ or more(219.1mm to 830mm) and a thickness range of 0.5mm to 59.54mm. The large-diameter welded stainless steel pipe has an outer diameter 219.1mm to1800mm and a thickness range from 0.5mm to 20mm
