SSAW steel pipe is formed by rolling and welding a steel strip in a helix or spiral direction, making the weld seam in a spiral line. The spiral welded process makes it possible to create large diameter options. Spiral submerged arc welding pipe is used in pipelines for the transportation and distribution of oil, natural gas, water and other flammable and non-flammable liquids. At the same time, it can be used in structures for construction and other general purposes due to the wide range of sizes.

For the transport of liquids: water supply, drainage. And for transporting gases: gas, steam, liquefied petroleum gas. It is also used for structural purposes: as piling pipe, for bridges, piers, roads, buildings and other pipe structures.

SSAW pipe diameter range is generally 8 inches to 140 inches (219.1mm to 3620mm). The wall thickness is 5.5mm to 24.5mm.

API 5L PSL1 Line Pipe covers seamless and welded carbon steel line pipe which suitable for use in conveying gas and oil industry. Our factory can offer a high-quality API 5L Gr.b line pipe to all of the worlds with an API certificate. API 5L gr.b ERW steel pipe is a very common steel grade, usually for psl1 gr.b pipe.

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
