Hot Dip Galvanized API 5L X65 JIS A5525 Saw Steel Pipeline

Hot Dip Galvanized API 5L X65 JIS A5525 Saw Steel Pipeline

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.

LSAW pipe (longitudinal Submerged Arc Welding Pipe) is fromed by JCOE with one straight welded seam, the outer diameters usually from 610mm to 1420mm. When the outer diameter is 914.4mm above, it’s allowed two straight welded seams. LSAW pipe is used to convey low pressure liquid meida or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation. The advantage for LSAW type is they could produce more thick wall thickness of pipes, maximum to 50mm.
