S355j2h Spiral Steel Pipe

The strength of S355j2h spiral welded pipes is generally higher than that of straight seam welded pipes. S355j2h  Welded pipes with larger diameters can be produced from narrower billets, and welded pipes with different diameters can also be produced from billets of the same width. However, compared with straight seam pipes of the same length, the weld length is increased by 30~100%, and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while S355j2h large diameter welded pipes mostly use spiral welding.
