Stainless Steel 446 Welded pipes are formed by cold or hot rolling plate and welding the seam. To keep the outside surface of a welded pipe uniform & smooth scarfing blade is used to remove the weld flash. ERW pipes stands for Electric Resistance Welded Pipes. Stainless Steel 446 ERW pipes are used in various scaffolding, line pipes, engineering purposes, fencing etc.
