What is an LSAW steel pipe?
(Longitudinally Submerged Arc Welding steel pipe) LSAW steel pipe in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production. A wide range of the finished product specifications, weld toughness, ductility, uniformity, and density, with a large diameter, wall thickness, high-pressure resistance, low-temperature corrosion resistance, etc. Required steel pipe in the construction of high-strength, high toughness, high-quality long-distance oil and gas pipelines, mostly large diameter thick wall LSAW.

Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance, and tight tolerances. LSAW pipes are also used in the conveyance of flammable & nonflammable liquids, and as structural members in construction projects.
LSAW pipe (longitudinal Submerged Arc Welding Pipe) is formed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm. When the outer diameter is 914.4mm above, it’s allowed two straight welded seams. LSAW pipe is used to convey low-pressure liquid media or high-pressure petroleum or natural gas and can be also used widely in structural supports or foundations. The advantage for the LSAW type is they could produce more thick wall thickness of pipes, maximum to 120mm.
