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.

Abstract: A hand-held OCTG length measuring apparatus has hollow upper and lower bodies, a hand grip extending generally downward from the hollow upper body near the first end and including a source trigger, and a sensor housing extending generally downward from the hollow upper body. The sensor housing encloses a TOF source operatively connected to the source trigger. The hollow lower body shaped to include a frontal cavity positioned generally under the source housing, the frontal cavity having attached thereto a pipe end alignment bracket. The upper hollow body and the lower hollow body connected at a lower end of the hand grip and at a lower end of the sensor housing. The apparatus employs a minimum 40,000 lux laser (at 18 to 25 feet) and a polarized, diamond-grade reflector, to afford reliable, repeatable OCTG length measurements.
Abstract: A device and method is taught for detection of flaws and localized wall loss in pipes made of ferromagnetic-based material. The device utilizes a magnetic field generator to create a horizontal magnetic field of flux. A pipe is passed through the magnetic field where a magnetic fluctuation detector, for example multiple groups of hall units, identifies fluctuations in the magnetic field.
