Abstract: To test transverse flanges terminating at a cylindrical wall of a workpiece, an installation includes a structure in a form of a U-shaped or C-shaped stirrup whose opposite branches carry respectively an ultrasound emitter transducer and receiver transducer, aligned with respect to one another, while leaving between them an internal space for relative passage of the flange to be tested, and whose base is mounted articulated at an extremity of a mobile control arm. The installation also includes an immersion canister including two parts assembled together by a closure mechanism, one of the parts exhibiting cutouts for engaging the transverse flange and for overlapping, with the other part, the flange up to the cylindrical wall of the workpiece.
