SSAW (also known as SAWH) steel pipe refers to spiral welded seam submerged arc welded steel pipe. The production process for this type of steel pipe involves continuously crimping steel plates into a spiral shape and welding the edges of the plates together by internal and external submerged arc welding to form a spiral weld seam for the pipe. This type of steel pipe is characterized by having a spiral weld seam, and its high production efficiency makes it suitable for manufacturing large-diameter steel pipes.
