SSAW Steel Pipe manufacturer in China

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.

Process of SSAW

SSAW Pipe (Spiral Submerged Arc-Welding Pipe), also called HSAW pipe (Helical SAW), welding line shape like a helix. It is using the same welding technology of Submerged Arc-Welding with LSAW pipe. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line.
