Abstract
High-speed tubular inspection systems include a frame at least one magnetic flux generator contained in a coil annulus and a detector assembly each having inlet and outlet openings for passing a tubular member there through. The detector assembly has one or more magnetic detectors and one or more eddy current detectors configured to be spaced a first distance from the tubular member during an inspection. The detectors are each contained in one or more EMI detector shoes. A conveyor supports the frame and a drive mechanism configured to drive the tubular member through the coil annulus (or drive the coil annulus past the tubular member) at high-speeds.
