Longitudinal Welds for Heavy Wall
LSAW pipe carries its weld along the pipe axis, allowing heavy wall thickness up to 40mm with tight dimensional control - the choice for high-pressure transmission and structural piling in the OD 325-1422mm range.
Standards and Sizing
Production covers GB/T3091-2008, JIS G3444 STK290-540, ASTM A139 and ASTM A252 GR.1-3 in 6-12m lengths. For spiral-welded alternatives up to OD 3500mm see our SSAW range.
