Abstract
Tubular member electromagnetic inspection apparatus, systems and methods for inspecting tubulars. An EMI shoe includes a generally arcuate body having a non-working major face, a working major face, a trough configured to hold one or more sensors embedded in a potting material, and at least one through hole for mechanical connection to an EMI apparatus. The generally arcuate body includes at least one non-central through hole in which are positioned respective externally threaded cylindrically-shaped set screws, each of the at least one non-central through holes having a wear-resistant friction member movably secured therein and positioned such that a distal portion of each wear-resistant friction member protrudes away from the major working face an initial distance (d1) and configured to wear down over time to a generally arcuate surface that is a distance d2 from the major working face, where d2<d1, forming a degraded wear-resistant member.
