  • Internal and external universal EMAT inspection devices and related methods
    Patent number: 9201045
    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.
