Abstract
An eddy current testing apparatus for nondestructive examination of pipe. The apparatus includes an eddy current coil adapted to removably circumferentially surround the pipe, the coil including a cable having a plurality of conductors adapted to form a continuous conductor coil when the cable is circumferentially wrapped around the pipe. A guide system extends along the length and adjacent to the surface of the pipe and a coil form is adapted to removably circumferentially surround the pipe and engage the guide system to provide for travel of the coil along the pipe.
