Advantage of induction pipe bending Induction bending does not require any sand filling or internal mandrels. The bending times are considerably less than in fire bending or weld fabrication, making the process cost effective. The quality of the bends with respect to surface finish are equal to that of cold bending, better than fire bending, and in the case of ovality and wall thinning, are superior. As the process eliminates the need for welded or mechanical joints between bends, the integrity of the finished pipe work is higher than in any other process.
