Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center The main purpose of spiral welded pipe and the difference Welding process The welding methods of spiral welded pipe and straight seam steel pipe are the same,but there are inevitably many T-shaped welds in straight seam welded pipe,so the probability of welding defects is greatly increased.Haihao Group can provide spiral welded pipes in different specifications,standards,materials.If you need,please contact us.Email [email protected]Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextHebei Zhuowei Steel Pipe Manufacturing Co.,Ltd.,Steel
