Abstract

The paper describes the evaluation of current state of the art Eddy Current Array (ECA) technology used for the detection and sizing of heat exchanger tube baffle plate erosion and fretting type defects. For validation purposes, all defects were also subject to Internal Rotary Inspection System (IRIS) ultrasonic evaluation. Results of the study indicate that a probability of detection (POD) figure of 84.6% is achievable for the ECA method with a probability of sizing (POS) mean measurement error of approximately +6.9% when compared to the IRIS sizing results.
