Height adjustable inspection shoes, apparatus and methods for inspecting tubulars

A body (2) for an electromagnetic inspection (EMI) shoe comprising:

• (a) the body (2) having a generally arcuate shape, a non-working major face (16), a working major face (17), a trough (4) configured to hold one or more sensor coils embedded in a potting material (34), and at least one through hole (14) for mechanical connection of the generally arcuate body (2) to an EMI apparatus;
• (b) the generally arcuate body (2) including at least one non-central through hole (6, 8, 42, 46) configured to have positioned therein respective adjustable externally threaded cylindrically-shaped set screws (10, 12, 40, 44), each of the at least one non-central through holes (6, 8, 42, 46) configured to have a wear-resistant friction member (18, 20, 30, 32) movably secured therein and positioned such that a distal portion of each wear-resistant friction member (18, 20, 30, 32) protrudes away from the major working face (17) an initial distance (d1) and configured to wear down over time to a generally arcuate surface (21) that is a distance d2 from the major working face (17), where d2<d1, forming worn friction members (18A, 20A, 30A, 32A), the adjustable externally threaded cylindrically-shaped set screws (10, 12, 40, 44) configured to be advanced further into the generally arcuate body (2) and thus advance the generally arcuate surface (21) to a distance d3, where d1≥d3>d2.
