Abstract
Tubular member inspection apparatus, systems and methods for inspecting tubulars of a variety of diameters. One apparatus includes a frame, at least one magnetic flux generator contained in a coil annulus, and a detector assembly supported by the coil annulus. The coil annulus and the detector assembly each have inlet and outlet openings for passing a tubular member there through. The detector assembly has one or more magnetic detectors (magnetic, eddy current, or both) configured to be spaced a first distance from the tubular member during an inspection. The one or more magnetic detectors are each contained in one or more detector shoes removably attached to corresponding one or more detector shoe supports by one or more quick-acting couplings. Another apparatus includes an adjustable iris.
