LSAW Steel Pipe

LSAW (Longitudinal Submerged Arc Welded) steel pipe is a large-diameter welded pipe with a single longitudinal weld seam.
It is manufactured by rolling steel plates into a tubular shape, then adopting submerged arc welding for seam joining, followed by ultrasonic inspection, hydrostatic pressure testing and anti-corrosion treatment.
It bears high pressure and large structural loads to transport gas, oil, water and other fluids safely over long distances.
It is widely used in oil & gas transmission, municipal water supply, bridge piling, thermal power plants, chemical pipeline and large infrastructure projects.
