In the operation of electric power plant, it is necessary to understand the condition of the pipe quantitatively. The purpose is to prevent the accident caused of the wall thinning portion due to erosion or corrosion. The thickness of the pipe is partially measured with the ultrasonic thickness gage now. However, it is difficult to investigate the wall thinning portion in the pipe quantitatively without confirming it beforehand. In this study, to identify the location of thinning for the purpose, the ultrasonic testing system using the guided wave was developed, that was able to investigate partially the wall thinning portion of all aspects of pipe to be inspected at a time. This system propagates guided wave by using an electro-magnetic acoustic transducer. An efficient pipe investigation becomes possible because it widely understand the condition of the pipe by using this system. The reliability improvement of facilities and the reduction of maintenance and repairs are expected to be attempted. In this report the actual results of applying the ultrasonic testing system were developed.
