SSAW (Spiral Submerged-Arc Welded) steel pipes are produced by winding hot-rolled plates or coils into a spiral shape and welding the edges. This method allows for the production of pipes with large diameters, making them ideal for transporting large volumes of oil and natural gas.

SSAW/SAWH pipes can be manufactured in a wide range of diameters, offering greater flexibility compared to ERW and LSAW pipes.
Utilizing narrower hot-rolled plates for production reduces costs, providing additional cost benefits to users.
These pipes exhibit strong stress-bearing capabilities, making them suitable for demanding applications.
