ABSTRACT:
An ultrasonic inspection apparatus for use in inspecting drill pipe or like tubular members being tripped into and out of a well borehole comprises a planarly arranged set of ultrasonic search units, such as wheel search units, arranged on a frame suspendible within the well derrick and defining a vertical passage for the tubular member. Access is provided to the passage by the tubular member from a direction transverse to the longitudinal axis of the tubular member, for example, by providing an openable hinged frame. When in the passage, the search units are urged into contact with and are sonically coupled to the tubular member. The device is manually manipulable to engage and disengage the tubular member to facilitate inspection. A method of inspecting tubular goods on the floor of a drilling rig during a tripping operation is also provided.
