| Abstract: | Basic eddy current principles and standard inspection procedures relating to heat exchanger tubing are briefly summarized. Various revolutionary probes recently introduced by Chalk River Nuclear Laboratories of Atomic Energy of Canada Limited are described. Included are: probes for inspecting ferromagnetic tubing, probes for detecting circumferential cracks and probes for detecting in regions, such as the tubesheet expansion zone, where conventional probes are not effective. |
