LSAW steel pipe means Longitudinal Submerged-Arc Welded Steel Pipe, which is actually built from hot-rolled steel plate or rolls. LSAW steel pipe constantly heads to the big-sized welded pipe, which can not be manufactured through electric protection welding strategy.

LSAW 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.

The application of liquid shipping like oil, water and fuel, building and constructions, chemical vegetation, power station, as well as foreign drill system.
