API 5L LSAW, OD610mm,wall thickness 15.9,

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing. LSAW pipes have large diameter, thick wall and can withstand high pressure and low temperature. LSAW pipes play a major role in oil and gas pipelines with features of high strength, high quality and long distance. According to the standard of American Petroleum Institute (API), the LSAW pipe is the only designated pipe in large scaled oil and gas transportation, especially when the pipelines cross the densely populated urban areas and the first and second class cities. 

LSAW (LSAW) in leaflets plate as raw material, the steel plate in the mold or molding device pressure (volume) into utilizing double-sided submerged arc welding and flaring from production. A large range of the finished item specifications, weld strength, ductility, harmony and thick, with a big diameter, wall thickness, high pressure resistance, low-temperature corrosion resistance, and so on. Needed steel pipe in the building and construction of high-strength, high durability, premium long-distance oil and gas pipelines, mainly large diameter thick wall LSAW.
