Role of Edge Trimming in the Production Process of Spiral Welded Pipes

The steel strip is continuously sheared by a circular shear to achieve a uniform width. The steel strips used for spiral welded pipes are typically round-edged materials, which have relatively large tolerances in width. There may be cases where the tolerance exceeds the specified limit. Therefore, the circular shear is used to control the material width, facilitating the forming accuracy of spiral seam double-sided submerged arc welded pipes.
