LSAW (Longitudinal Submerged Arc Welding) Steel Pipe is manufactured by forming steel plates into a cylindrical shape and welding the longitudinal seam through submerged arc welding technology. With high welding strength, excellent dimensional accuracy, and reliable performance, LSAW pipes are widely used in large-scale pipeline projects, oil and gas transportation, water transmission, construction, and structural applications.
Our LSAW steel pipes are produced according to international standards and can be customized to meet different project requirements.
