304 stainless steel welded pipe

Advanced Manufacturing Process of Stainless Steel Welded Pipe

The production of premium stainless steel welded pipe begins with casting slabs or billets in specialized steel mills. The manufacturing process employs several advanced welding methods, determined by the desired external dimensions and wall thickness:

• Electric Resistance Welding (ERW)
• Fusion Welding (EFW)
• Double Submerged Arc Welding (DSAW)

During ERW and EFW processes, stainless steel welded pipe formation involves hot or cold rolling of plates followed by precise seam welding. To ensure superior quality, a scarfing blade maintains smooth surface uniformity by removing weld flash from both outside (O.D.) and inside (I.D.) surfaces. Final heat treatment minimizes weld zone visibility, though ASME standards specify lower operating pressures compared to seamless alternatives.
