In thermal, nuclear, and other power generation plants, there is a need to shorten the periodic inspection process, and the establishment of highly efficient inspection services is desired. However, since the inspection of corrosion thinning of plant piping and boiler heat transfer tubes entails incidental work such as temporary scaffolding and removal of scale on the outer surface of the tubes, there is an issue of reducing the time and cost associated with such incidental work. As a measure to address the issue, we have developed an inspection service that can efficiently screen the wall thinning of plant piping with minimal incidental work, and an inspection service that can measure the wall thickness and inner scale thickness of boiler heat transfer tubes without removing the outer surface scale. These services reduce the amount of incidental work required for the inspection of corrosion thinning in plant facilities, which contributes to shortening the periodic inspection process.
