Abstract
Apparatus and device for testing within a metal pipe are described. The apparatus includes an exciter for generating an electromagnetic (EM) field for exciting a wall of the metal pipe; an extendable and retractable sensor assembly comprising a plurality of sensor bars arranged in an angled manner with respect to an axis of the pipe for sensing residue EM field on a wall of the pipe; a plurality of guide wheel assemblies for supporting and moving the apparatus along the axis of the pipe; and a control unit for recording sensed data from the sensor assembly.
