摘要： Mounting system for maintaining a transducer (20) in contact with a pipe (12)during the verification. The system is mounted on a frame (32) which is in turn movablymounted on a length of pipe. A first stage of the verification procedure is to position theframe (32) has a distance from the pipe according to the diameter thereof. A carriage (34)coupled to the frame is then decrease a scanning position and the scanning is carried outas a measure that the frame moves along the pipe. A mechanism of the universal joint (36)for connecting the carriage to the transducer (20) allows horizontal and vertical

movements of the transducer, thereby permitting even continuously scan for presentingarques pipes or other irregularities along their length. When one arrives at the end of thepipe, the carriage (34) is distant from the pipe (12) by means of a spring mechanism (1).In this retracted position any displacement downwardly of the transducer is prevented bya support a ball (146, 147) and couples the transducer into contact with a supportsurface (149) of the carriage. The transducer can thus fall from the pipe extremity orcollide with it thereby avoiding damage to the transducer assembly.
