Ultrasonic pipe inspection system

摘要

Remote-controlled system for moving an ultrasonic transducer assembly around a pipe where it has a welded joint between a straight pipe section and a curved or straight pipe section. The system includes a platform movable along an arm projecting from a carriage on a track around the pipe, and a pressure cylinder and universal joint connecting the platform to the transducer assembly. Couplant fluid is fed continuously to the surface of the assembly engaging the pipe as it slides over the pipe.
