Longitudinal-seam Submerged Arc Welded (LSAW) pipes

1.Manufacture For Large-diameter(25 centimetres (10 in) or greater) pipe, usually used ERW(Electric resistance welding),EFW(Electric fusion welding) or Submerged Arc Welded(SAW),but there are tow technologies,with these we can manufacture larger size pipes than seamless and ERW process!They are Longitudinal submerged arc welded (LSAW) and Spiral submerged arc welded (SSAW) pipes. Manufacturing Technology of Large Diameter LSAW Steel PipeThis method can form welded pipes with different pipe diameters and different wall thicknesses. The processed diameter can be less than 406mm, and the quality of the welded pipe produced is better. Good, moderate yield. Tips:Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe.
