Huaxi Special Steel Manufacturing Co., Ltd

LSAW (Longitudinal Submerged Arc Welded) steel pipe is manufactured by forming steel plate into a cylindrical shape and welding the seam parallel to the pipe axis using the submerged arc welding (SAW) process. Compared with other welded pipe types, LSAW pipe is particularly suitable for large diameters and heavy wall thicknesses while maintaining excellent dimensional accuracy and weld integrity.

Due to its structural strength and manufacturing characteristics, LSAW steel pipe is widely specified for pipeline, structural, offshore, and infrastructure projects that require reliable performance under demanding operating conditions.
