Spiral steel pipe product performance

The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. It can produce welded pipes with larger diameters using narrower billets, and can also produce welded pipes with different diameters using billets of the same width. However, compared to straight seam pipes of the same length, the weld seam length increases by 30-100%. Therefore, smaller diameter welded pipes mostly use straight seam welding, while large-diameter welded pipes mostly use spiral welding.
