Description of SSAW Steel Pipes

SSAW welded steel pipes (Spiral Submerged Arc Welded Pipes ) are manufactured from steel plates that are cut into strips, shaped by a series of forming rolls, and welded together.

The SSAW steel pipe is formed by rolling a coiled steel strip into an elliptical shape and welding the ends together to form a spiral seam. This method allows for more flexibility when manufacturing large-diameter pipes, as it eliminates many of the constraints.
