"Sizing of Inside Diameter Pits in Tubing Utilizing Two-variable Regression Curves" is the latest technical paper written by our NDT experts Christopher J. Speas and J. Fred Hall
This article published in the September, 2011 issue of Materials Evaluation discusses inside diameter (ID) pit depth sizing using eddy current testing in heat exchanger tubing. The purpose of this paper is to compare traditional methods such as phase angle and amplitude analyses with a two-variable calibration curve approach in order to improve sizing accuracy.
