Stainless Steel Welded Tube ASTM A554 TP304 Water engineering petrochemical Oil
What is Welded tube?
Welded steel pipe, also known as welded tube, is a steel pipe made of steel plate or strip after roll forming and welding, generally 6 meters in fixed length. Welded steel tube production process is simple, high production efficiency, a variety of specifications, less investment in equipment, but generally lower strength than seamless steel tube
