Stainless Steel Welded Pipe Stainless Welded Pipe

Stainless steel welded pipe is manufactured by rolling stainless steel plate on a machine then welding the seam. A scarfing blade then removes the weld flash from the inside and outside of the pipe. Many processes heat treat the welding zone to make the seam less visible and provides a more complete finish to the pipe.
