LSAW Super Thick Wall Double Seams Steel Pipe

  • Difference between ERW, SSAW, LSAW - Sunny Steel

    Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).

  • Types of Oil & Gas Pipes Seamless, ERW, LSAW ...

    The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.

  • What is The Differences Between LSAW Pipe and SSAW Pipe

    LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

  • LSAW Steel Pipe Definition - permanentsteel

    LSAW steel pipe is a cylindrical shape in which a hot rolled coil is formed by a forming machine and deforms the coil into a smooth shape, and is welded by using a skin effect and a proximity effect of a high-frequency current or an arc burning under a layer of the solder. The edge is heated and melted, and it is fused under a certain squeezing force and finally cooled to form.
