LSAW PIPE

LSAW (Longitudinal Submerged Arc Welded) Steel Pipe is produced by forming steel plate

into a cylindrical shell and welding a single longitudinal seam under granular flux,

following the API 5L PSL2 specification. Compared with ERW and SSAW pipes,

LSAW offers superior dimensional accuracy, consistent wall thickness and reliable weld quality,

making it the preferred choice for high-pressure oil, gas and water transmission pipelines.
