ABSTRACT:
An apparatus for detecting irregularities in a ferrous pipe includes a magnetizing coil for inducing a magnetic field in the ferrous pipe. Inspection shoes measure changes in the induced magnetic field and produce signals representative of those changes. An analog-to-digital converter digitizes the measured signals representing the changes in the induced magnetic field. A processor processes the signals according to frequency to classify the signals by type of irregularity in the ferrous pipe. A screen and/or printer displays the frequency processed signals according to type of irregularity in the ferrous pipe.
