Apparatus and method for inspection of tubes in a boiler

摘要

An apparatus and method for inspection of tubes in a boiler is disclosed. The apparatus (10) includes a sensor (11) adapted to generate and detect guided-waves and a mechanical device (12) adapted to reach into a tube bundle and clamp the sensor (11) onto an interior tube selected for inspection. The mechanical device (12) includes a housing (13) adapted to contain the sensor (11) and an air cylinder (14) adapted to actuate the housing (13) to allow the housing (13) to clamp onto the interior tube.
