Spiral welded steel pipe (SSAW steel pipe), Spiral submerged arc pipe, Spiral pipe & tube
Spiral steel pipe, also known as spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the tube seams. It can produce large-diameter steel pipes with narrower strip steel.
Features:
The production process of straight seam welded pipe (ERW/LSAW) is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can produce welded pipes with larger diameters with narrower billets, and can also produce welded pipes with different diameters with billets of the same width. However, compared with straight seam pipes of the same length, the weld length increases by 30~100%, and the production speed is lower. Therefore, most smaller diameter welded pipes use straight seam welding, while large diameter welded pipes mostly use spiral welding.
