| Abstract: | Cavities in steel pipes were analyzed. The magnetic flux leakage fields of cavities were studied on the basis of mathematical model and the three dimensional model made with emulation software Ansoft. The magnetic flux leakage signals were processed and the relationship between the signals and cavity radius was obtained, which offered a reference for the recognition of cavity signals. |
