Abstract: Embodiments include an electromagnetic acoustic transducer (EMAT) system. The EMAT system includes a plurality of magnets and a conductor set. The plurality of magnets has a like pole arrangement and wherein each magnet is in close proximity to one another. The conductor set includes electrically conductive elements. A portion of the conductor set is positioned proximate to the plurality of magnets. The plurality of magnets and the conductor set are positioned proximate to a test object. The EMAT system is configured to perform at least one of generating and receiving an elastic wave. Embodiments also include a method of elastic wave measurement for nondestructive testing and evaluation.

Abstract: Systems, devices, and methods of inspecting a body of a tubular, are provided. An exemplary electro-magnetic acoustic transducers (EMAT) tubular inspection system for inspecting a body of a tubular includes an EMAT in-line tubular inspection device. The device can include a spine having a longitudinal support body and radially projecting rails, and multiple telescoping sections each connected to the radially projecting rails. The telescoping sections can include a magnetic back panel, one or more wheels positioned to engage an inner surface of a body of a tubular during inspection, and signal propagating and receiving modules carried by the magnetic back panel. Each module can include a magnet and different types of EMAT inspection transducer coil arrangements connected to the magnet. The different types of EMAT inspection transducer coil arrangements provide for the generation of NBSH, SW, and SV waves.

Abstract: Systems, methods and program products of instructions stored on a computer readable medium related to a tether free piggable inspection tool capable of detecting holidays and able to read and store non-conductive internal coating thickness values in very long conductive pipes, along with distance values for further off-line analysis, are provided. The inspection tool includes a plurality of thickness probes, a data storage unit, a control unit, a plurality of navigation wheels and a holiday detector that uses an electrical conductive medium, such as a gas or fluid, as the ground connection. A closed loop configuration is adopted allowing the system to autocorrect itself for different coating thicknesses along the pipe.
