SSAW / SAWH Pipe

"Spiral Strength for Large Diameters"

Spiral Submerged Arc Welded. Also known as HSAW (Helical).

"The Spiral Core"

Think of the cardboard core of a paper towel roll. It's wrapped spirally to create a wide, stiff tube from a narrow strip of paper. SSAW applies this geometry to steel to create massive pipes that act as the legs for bridges and piers.

Formed by rolling steel strip in a spiral motion. This allows the production of very large diameter pipes from standard width coils. The spiral weld distributes stress evenly. Mainly used for Piling (Ports/Bridges), Dredging, and Water Transmission.
