More  details

Our stainless steel welded pipes are produced using a complete set of standardized processes including uncoiling forming, precise welding, and solution heat treatment. This effectively eliminates the internal stress caused by welding, refines the microstructure of the pipe material, and completely resolves the problems of cracking, rusting, and uneven hardness after pipe welding, significantly enhancing the toughness and corrosion resistance of the pipes.
