Sizes of LSAW Steel Pipe: LSAW pipe, DSAW pipe, longitudinal welded pipe - steel LSAW(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, it's allowed two straight welded seams.

    Longitudinal Submerged Arc Welding (LSAW) Processes

    Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes 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 processes. Longitudinal Submerged Arc Welding LSAW Steel Pipes LSAW Steel Pipe s (longitudinal submerged arc welding) are usually the most economical solution when high wall thickness is required due to high internal or external pressure. LSAW Steel Pipe s are larger in diameter than ERW (resistance welding), typically from 16 inches (406 mm) to 60 inches (1500 mm).

    What are differences between SAW pipes and ERW pipes

    Whereas LSAW pipes are used for medium to high-pressure services.SSAW pipes are less costly compared to LSAW pipe. ERW steel pipe manufacturing method:When ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc shaped and rotate as the material passes between them. What is EFW steel pipe - pipelinedubaiOct 25, 2018 · EFW steel pipe (Electric Fusion Welding steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. EFW steel pipe is formed by rolling plate and welding the seam.
