Used for low pressure liquid delivery, such as water, gas, and oil, SSAW is spiral submerged arc welding for short. Major applications of SSAW pipes are widely applied in oil, natural gas, water and other flammable & nonflammable liquid conveyance and distribution pipelines, steel structures for construction and other general purposes by means of their wide size range. SSAW pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same specification can produce SSAW pipes with various diameters. The welding joints can avoid major stress and have better force resistance.
