Carbon Steel API 5L X65 PSL1 SAW Steel Pipe For Pipe Line

Carbon Steel API 5L X65 PSL1 SAW Steel Pipe For Pipe Line

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/RBE.
