Product Details

406.4mm GB/T 9711.1 LSAW Steel Pipe For Conveying Gas

Out Diameter : 406.4mm - 1422.4mm (1 6 "- 56 " ) GB / T 9711.1 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 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.

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 conveyance of flammable & nonflammable liquids, and as structural members in construction projects.
