JOCE LSAW PIPES(PRESS BENDING) This is large diameter longitudinal submerged arc welded (LSAW) pipe production line in China. The mill adopts progressive bending process, featuring evenly distributed forming stress, high uniformity of dimension, infinite sizes variation&wide prouct range, and high flexibility, etc. LSAW Steel Pipe - Arabian PipesLSAW Steel Pipe. APC LSAW Steel Pipe Plant, is located in the Industrial City of Jubail and specializing in the manufacture of Longitudinal Submerged-Arc Welded (LSAW) carbon steel pipe for the Oil and Gas, Petrochemical, Agricultural and Construction Industries. LSAW Steel Pipe, DSAW Steel Pipe - Seamless Steel PipeLSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.
Metline is a specialized manufacturer and factory supplier of Longitudinal Submerged-Arc Welded (LSAW) carbon steel pipes for the Oil and Gas, Petrochemical, Agricultural and Construction Industries. We can supply high quality LSAW pipes with various standards, including but not limited to API 5L GR A, GR B, X42, X46, X56, X60, X65, X70. Longitudinal Submerged Arc Welding LSAW Steel Pipes 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. Considering this, the main applications of pipeline LSAW Steel Pipe s include oil, natural gas, natural gas, central heating, water supply, sewage treatment and 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 process.
Jul 21, 2018 · LSAW pipe (longitudinal Submerged Arc Welding Pipe) is fromed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm. When the outer diameter is 914.4mm above, its allowed two straight welded seams.Longitudinally Submerged Arc Welded Steel pipes, LSAW Double welding wire automatic submerged arc welding machine This machine is used to weld the longitudinal seam as well as circumferential seam. It has double welding wire and the maximum current is 1500A, and its welding speed can reach 1.2m/min.The welding head can revolve freely so that circumferential seam is available.
