Description

In this study, the acoustic emission signal and background noise value associated with leakage through steam and water valves (4/3∼10 inch valves) has been investigated at site. Results from the simulated experiment were compared with data from the power plant. To attain a threshold level of detectable acoustic emission, background noise data in site were measured. As a result of these studies, we conformed that it can be a optimal method for assessing valve leakage and background noise in actual power plant to compare with between obtained results in laboratory and actual measuring data from the power plant valves
