Abstract: A system for ultrasonic inspection of a tubular member using an ultrasonic inspection unit having a platform, a guide member with a longitudinal axis, a wheel connected to the platform and contacting a surface of the tubular member for moving the platform along and around the tubular member relative to a rotation of the tubular member, and a bearing support connected to the platform at a location spaced from the wheel. The bearing support contacts the guide member for supporting the platform on the guide member and allowing the platform to move longitudinally in a direction along the longitudinal axis of the guide member in response to the moving of the guide wheel. A tubular member rotation mechanism receives the tubular member and rotates the tubular member around a longitudinal axis of the tubular member.

Abstract: A cart for inspecting a drill pipe having a platform with an ultrasonic inspection unit thereon, a first pair of wheels connected to the platform so as to move the platform longitudinally along the drill pipe relative to a rotation of the drill pipe, and a bearing connected to the platform at a location distal of the first pair of wheels. The bearing serves to support the platform above an adjacent drill pipe and allows the platform to move longitudinally along the adjacent drill pipe in correspondence with the movement of the first pair of wheels. The first pair of wheels are canted at an angle relative to the longitudinal axis of the drill pipe. A sensor wheel extends outwardly of the platform and rotates during the movement of the platform along the drill pipe. The platform has at least one handle extending upwardly from the platform. The bearing includes a pair of rollers that have an axis of rotation which is transverse to the longitudinal axis of the adjacent drill pipe.
