Abstract
Valve is a critical device to control fluid flow as an in-plant installation. However, much accidents due to an out-of-control valve have been reported in the past. One reason that the valve will become out-of-control is a Fixation-damage due to corrosion. It is important to evaluate the structural integrity of valve installed in plants because a fixation-damage causes serious accidents. For the purpose of developing a structural integrity monitoring system of valve, an attempt is made in this study to classify structural integrity of valve from vibration image data by using convolution neural network.
