概要

In this study, we developed a method to measure pipe wall thinning by electromagnetic acoustic resonance method (EMAR) which is one of electromagnetic ultrasonic method. The EMAR can evaluate the thickness of piping with high accuracy. In addition, we propose a method to obtain the resonance frequency with high accuracy when the thickness reduction progresses and the SN ratio decreases. We applied the technology to PWR and BWR pipings and examined its applicability.
