Part I and Part II


April 11, 2006


Have you ever started with what you thought was a good tube, ended with a bad bend, and wondered where you took a wrong turn? Correcting for defects requires some detective work, and an understanding of the bending process. This article examines tube defects and offers fixes.

Editor's note: "When a good tube bends bad" is a two-part article that examines tube bending defects, possible causes, and suggested remedies. Part I discusses surface defects; Part II covers other defects, such as wall thinning, ovality, buckling, and fractures.
