Stainless steel welded pipes shall be made by the manual or automatic electric-welding process. It shall be made from flat-rolled stainless steel sheet, coils, or plate by a shielded arc-welding process. Stainless welded pipes shall be furnished clean and free of scale.
All stainless welded pipes shall have smooth ends free of burrs and shall not deviate from straightness by more than 0.8mm in 900mm of length.
Stainless steel welded pipe, after final heat treatment, shall be chemically descaled or pickled free of scale. When bright annealing is used, pickling or chemical descaling is not necessary.
Jiangsu Sheye Metal is a leading manufacturer and supplier of stainless steel welded pipe. Stainless welded pipes are inventoried in 6.0mm to 1219mm.
All welded pipes can be cut into specified size. Finish processing service, like polishing, can be available. We can process stainless welded pipes to mirror finish. For metal, we are serious.
