Introduction to LSAW Pipe
Longitudinal Submerged Arc Welded (LSAW) pipes are a type of welded steel pipe. They are produced by bending a steel plate into a cylindrical shape and then welding the seam longitudinally using the submerged arc welding process. This manufacturing method allows for the production of large - diameter and high - wall - thickness pipes. LSAW pipes are widely used in various industries such as oil and gas transportation, water supply, and structural applications due to their excellent mechanical properties, high strength, and good weld quality.
