Abstract

The apparatus comprises a mounting (1) jig positioned in alignment with the tube (2) to be inspected; means of achieving relative movement between the jig (1) and the tube (2) along the latter's axis means of axial guiding and adjustment of the end of the tube; two feelers (17, 18) positioned in a diametric plane of the tube (2) and able to make contact with the internal and external faces respectively of the tube walls; means of suspending the feelers allowing relative elastic movement between them along one or more directions perpendicular to the tube axis; means of controlling the spacing between the feelers; and means of display or command linked to the control means.
