LSAW Steel Pipe

LSAW steel pipe, say, longitudinal submerged arc welding pipe, is using double-sided submerged arc welding process, welding in static conditions, thus can get high weld quality, short weld  seam, low probability of potential defects. Expanding diameter through whole length. Appearance well, size precision, wide range of steel tube wall thickness and pipe diameter , range of diameter up to 406-1829 mm diameter, wall thickness 6.0-60 mm, higher degree of automation, compared with seamless steel tube, the production cost is lower, suitable for upright load bearing,   large span construction structure and  wind and earthquake resistant electricity tower mast structure of buildings, Bridges, DAMS, offshore platform etc.
