  • Apparatus for inspecting a tube
    Patent number: 9804129
    Abstract: An apparatus for inspecting a tubular workpiece may include a probe assembly and a rotation mechanism. The probe assembly may include a transducer array positionable adjacent to an inner surface of the tubular workpiece. The probe assembly may generate transmitted sound waves and may receive reflected sound waves. The rotation mechanism may rotate the probe assembly relative to the tubular workpiece in a manner such that the transducer array passes over the inner surface in a circumferential direction during transmission of the transmitted sound waves.
    Type: Grant
    Filed: October 30, 2014
    Date of Patent: October 31, 2017
    Assignee: The Boeing Company
