Spiral Submerged Arc Welded (SSAW) pipe is manufactured by spirally forming coiled steel strip into a tube and welding the seam with submerged arc welding, giving a continuous helical weld that distributes stress evenly around the pipe wall. This process is highly efficient for producing large-diameter pipe from a single coil width, and SSAW pipe is widely used for water and gas transmission pipelines, marine and offshore piling, structural piles, and general fluid conveyance where cost-effective large diameters are required.
