Longitudinal Submerged Arc Welding (LSAW) Processes

In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. 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. Problems to be solved in the construction - United SteelMar 26, 2018 · From the comparison of several large longitudinal welded pipe technology and the development analysis of large longitudinal welded pipe technology in the world, UOE is the main DSAW tube unit in the world to produce high strength pipeline steel pipe. Its production capacity is large and the quality of the product is good.

Petrosadid:Longitudinally Welded and Double SAWWelded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW). DSAW Pipe is often produced by automatic double-wire double-sided submerged arc welding
