LSAW (Longitudinally Submerged Arc Welded) steel pipes are manufactured by welding a single medium-to-thick steel plate that has been formed into a tube shape through pressing or rolling. The welding process involves double-sided submerged arc welding, followed by expansion to achieve the desired diameter. These pipes are known for their wide range of specifications, excellent toughness, plasticity, and uniform weld quality. Their key features include large diameters, thick walls, high pressure resistance, low temperature resistance, and resistance to corrosion. LSAW pipes are commonly used in the construction of high-strength, long-distance oil and gas pipelines due to their robust characteristics.
