ABSTRACT:
A device for checking bent tubes by means of a probe, such as a pneumatically propelled eddy-current probe. The device comprises a sealing-tight enclosure adapted to communicate with the tube to be checked via a connecting tube. The introduction pressure of the probe is produced by a pneumatic circuit. The probe comprises a checking head and a cable having floaters and is wound on a coil driven by a torque motor. The introduction speed of the probe is controlled by passing it over a drive pulley, to which it is permanently applied by a strap tensioned by a spring, the pulley being mounted on the shaft of a constant-speed motor. Application to the checking of the tubes of heat exchangers, condensers and steam generators, more particularly of nuclear reacters.
