Spiral Submerged Arc Welded Steel Pipe(SSAW or HSAW), utilizing hot-rolled steel strip as raw material, is formed through a spiral rolling process and welded using submerged arc welding technology. Its defining characteristics include a spirally distributed weld seam and the capability for unlimited fixed lengths, achieved by adjusting the strip's forming angle.

Key Features
* Large Diameter can be produced by SSAW (max to 3000mm)
* Cost-effective: Different from LSAW pipe which is produced from a whole plate with big width by longitudinal welding, SSAW is produced from steel coil in 1000 or 1500mm width by sprial welding , SSAW is Cost-effective
