概要
A pipe-wall thinning measurement is required to ensure integrity of a piping system in a power plant. Aiming to reduce the inspection time of the pipe-wall thinning measurement, we have been developing an innovative measurement technology which enables the pipe-wall thinning inspection without removing the insulation, based on the non-contact ultrasonic sensor. To confirm applicability of this sensor to the pipe-wall thinning inspection in actual plants, we performed the thickness measurement tests by using the pipe which simulates the actual plant pipe including the insulation. From the experiment results, we confirmed that the bottom echo can be properly obtained through the insulation and the non-contact ultrasonic sensor can be applied to the actual plant inspection.
