LSAW steel pipe (Longitudinally submerged arc welding 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 dense, 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.
