Acceleration sensor Boiler Leak detection Steam Thermal power station Tube leak
A steam tube-leak is a very critical issue in industrial plants because the steam jet from the damaged point immediately causes damage to the surrounding tubes. Therefore, an early detection of the tube leak is important to reduce the maintenance cost and the outage time. In this study, we conducted a detection test of the steam tube leak using acceleration sensors; they are expected to catch a radial tube-vibration induced by acoustic propagation. Through the test, we found that the sensor detected a radia...

non-contact measurement Pipe-wall thinning ultrasonic testing wireless sensor
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 proposed by University of Bristol. To apply this technology to the actual plant inspection, sensor calibration and extension of measurable thickness ...
