Skelp edge preparation for manufacturing ERW pipe
The primary considerations for using rotary shearing to remove or separate material are: 1. Force and power requirement. 2. Tooling performance. 3. Effects of the process on the physical properties of the material. 4. Condition of the surface of separation. An operator has no control over the shape of the skelp. Skelp shape, good or bad, reflects the material's cross-sectional contour. Problems that cause bad shape include edge wave, end hook, camber, center buckle, or oil canning.
