Product Description:

LSAW is a kind of steel pipe molding mode: JCO process, welding it, and expanding the diameter mechanically at last. It is featured by protection of materials, high molding rate, and effective guarantee of higher mechanical property of steel tubes made of same materials. Longitudinal seam double-sided submerged arc welded steel tubes, with high strength, high toughness, high tensile strength, high corrosion resistance and acid resistance, can be used for undersea petroleum and gas pipelines, land petroleum and gas pipelines in severe cold areas and places with big fall, and coal slurry and ore slurry pipelines. This kind of steel tubes is widely used in important oil and gas pipelines in the global.
