LSAW Steel Pipe Is A Straight Seam Submerged Arc Welded Pipe Terminology

Edit:Ausin Pipeline Material & Equipment Co.,Ltd   Date:Jul 05, 2017

  LSAW steel pipe is a professional expression term for straight seam submerged arc welded steel pipe. LSAW steel pipe is a single plate as raw material, the steel plate in the mold or molding machine in the pressure (volume) into a tube, the use of double-sided submerged arc welding and expansion from the production. Its finished product range is wide, the toughness, plasticity, uniformity and compactness of the weld are better, and it has the advantages of large diameter, thick wall, high pressure resistance and low corrosion resistance. In the construction of high-strength, high-quality long-distance oil and gas pipelines, the required steel pipe is mostly large diameter thick-walled submerged arc welded pipe. According to the API standard, in the large oil and gas transmission pipeline, when through the alpine zone, the seabed, the urban population density area 1 class, 2 type area, straight seam submerged arc welded pipe is the only designated tube type.
