Spiral welded pipes
In this process the weld is created in the exact same manner as that of DSAW, only the weld seam takes on a helical or spiral appearance due to the way the skelp is rolled to form. Just as in the case with the ERW and DSAW process, a continuous ribbon of skelp is leveled and sent through a series of rolls to form. The spiral weld process also allows the mill to roll a much wider range of sizes than DSAW or ERW mills. However spiral welded pipes have limitations in rolling pipes beyond 25 mm in higher grade of X 70 , X 80. Also, due to its axial symmetry, spiral weld carbon steel pipe has an inherent ability to maintain straightness. Common spiral weld specs include API5LB and A252.
