Carbon Steel LSAW ERW X65 X70 X80 BS 1139 Mild Welded Casing LSAW Carbon Steel Pipe

LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater. In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.

  • Our engineers can provide you with the best solution for your industry-specific application requirements.

  • Our pipes can be sold all over the world with short lead times and excellent product quality.

  • Our sales team is on call 24 hours a day, we will contact you as soon as we receive your letter.
