The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process. Longitudinal Submerged Arc Welding LSAW Steel Pipes Longitudinal Submerged Arc Welding LSAW Steel Pipes Processes Longitudinal submerged arc welding is a special welding technology used in pipe production. Because of high internal or external pressure, the final product needs high wall thickness. Mechanical properties of longitudinal submerged arc welded To research and develop domestic steel pipes used for the submarine pipeline, the Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter J, C, O or U shape, then expansion) forming

Pipeline Transportation Systems for Liquids and - ASMEdouble submerged arc welded pipe:pipe having a longitudinal or spiral helical seam butt joint produced by at least two passes, one of which is on the inside of the pipe. Coalescence is produced by heating with an electric arc or arcs between the bare metal electrode or
Submerged arc welded steel pipe. (3) For pipes with high requirements for internal and external anti-corrosion coatings, straight seam submerged arc welded steel pipes shall be used. Spiral submerged arc welded steel pipe has many weld beads. The weld bead height is generally higher than that of straight seam submerged arc welded steel pipe. Selection of Straight Seam Submerged Arc Welded Steel PipeSubmerged arc welded steel pipe. (3) For pipes with high requirements for internal and external anti-corrosion coatings, straight seam submerged arc welded steel pipes shall be used. Spiral submerged arc welded steel pipe has many weld beads. The weld bead height is generally higher than that of straight seam submerged arc welded steel pipe. Submerged Arc Welded - Saw Pipes Reliable Pipes & Submerged Arc Welded - Saw Pipes. SAW or Submerged Arc Weld, as the name suggests, is a manufacturing method for large diameter Welded Pipes. SAW pipes are mainly are classified into Helical / Spiral SAW (HSAW) and Longitudinal SAW (LSAW). Generally large diameter pipes from Size 12¾ (324mm) onwards can be manufactured in LSAW construction
With seamless welding quality, these longitudinal seam submerged arc welded steel pipe are annealed with nitrogen protection and are polished with utter professionalism. These products are made of robust materials such as carbon steel, stainless steel, galvanized surface-treated iron and many more to offer consistent service for a long time. Longitudinal-seam Submerged Arc Welded (LSAW) pipes Longitudinal-seam Submerged Arc Welded (LSAW) pipes The material of LSAW steel pipe is unit middle or heavy thickness sheet,coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.the specification scope is wide,and have good toughness, ductility, uniformity, compactness.
