1. A tubular member electromagnetic inspection (EMI) apparatus comprising:
(a) a frame (2);
(b) at least one magnetic flux generator (4) contained in a coil annulus (8) and a detector assembly (6) supported by the coil annulus (8);
(c) the coil annulus (8) and the detector assembly (6) each having inlet and outlet openings (10, 12) for passing a tubular member (14) there through, the detector assembly (6) having one or more magnetic detectors (16) (magnetic, eddy current, or both) configured to be spaced a first distance from the tubular member (14) during an inspection; and
(d) the one or more magnetic detectors (16) each contained in one or more detector shoes (18) removably attached to corresponding one or more detector shoe supports (20) by one or more two-part quick-acting couplings (22), the one or more detector shoe supports (20) each comprise a non-telescoping member (24) of length selected corresponding to diameter of the tubular to be EMI inspected, each non-telescoping member (24) removably attached to an inner surface (28) of the coil annulus (8) by one or more two-part quick-acting couplings (26).
