ISO 14001 A53B API 5L X70 Saw Oil Transmission Pipeline

What is a 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.
Straight seam submerged arc (LSAW steel pipe) is produced by using a single medium-thick plate as the raw material, pressing (rolling) the steel plate in a mold or forming machine, using double-sided submerged arc welding and expanding the diameter. The finished product has a wide range of specifications, good toughness, plasticity, uniformity and compactness of the weld, and has the advantages of large pipe diameter, pipe wall thickness, high pressure resistance, high temperature resistance and corrosion resistance. When constructing high-strength, high-toughness, high-quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick-walled straight-seam submerged arcs. According to API standards, in large oil and gas pipelines, when passing through Class 1 and Class 2 areas such as alpine areas, seabeds, and densely populated urban areas, straight submerged arcs are the only designated pipe types. According to different molding methods, it can be divided into: U0E/JCOE/HME.
