Professional welded, seamless, firefighting steel pipes, coils and sheets manufacturer since 1991
Our SSAW steel pipes are manufactured and certified by API certification , ensuring high-quality performance and durability for various pipeline construction projects.
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 steel pipeline diameter range is generally 8 inches to 140 inches (219.1mm to 3620mm). This steel pipeline wall thickness is 5.5mm to 24.5mm.
Standard of SSAW Pipe
We provide all grade of these standards:
API 5L: A, B, X42, X46, X52, X56, X60, X65, X70, X80;
