| Research Abstract |
In this study, a pipe inspection system using electromagnetic phenomenon for surface corrosion of pipes covered with heat insulators is developed. An electromagnet to produce a rotating magnetic field was created for the pipe inspection system ; it was confirmed to have an enough performance. To improve inspection accuracy of the surface corrosion of pipes, measurement conditions of impedance at the frequency were examined ; the specific frequencies to improve inspection accuracy were found.
