SUS 304 Large-diameter Double-seam Welded Stainless Steel Square Tube for Transport Pipe
SUS 304 Large-diameter Double-seam Welded Square Pipe For Transport Pipe
Product Description
304 double seam welded stainless steel pipe (304 Double Seam Welded Stainless Steel Pipe) is a stainless steel pipe made by forming a 304 stainless steel strip sheet and then welding two seams together. Due to the difficulty of meeting the size requirements with a single weld seam during the production of large-diameter pipe materials, the double seam welding process is adopted.
