SSAW Pipe

SSAW (Spiral Submerged Arc Welded) Pipe is manufactured by hot-rolled steel coil, continuously formed into spiral shape and welded by double-sided submerged arc welding process.

It has the advantages of large diameter, flexible size, high pressure bearing capacity, strong rigidity and stable welding performance. It is widely used in long-distance oil & gas pipelines, water supply and drainage projects, sewage treatment, piling for bridges and ports, structural steel pipe, slurry transportation and other low-pressure to medium-pressure engineering fields.
