Minimizing wall thickness variation in seamless tubing

August 28, 2003

By:

All mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.
