défauts au moyen d 8 ultrasons ou par des moyens similaires. defects by ultrasound or similar means.
Lors du contrôle de tubes, par exemple pour la mesure de ltépaisseur de paroi et/ou la détection de défauts au moyen d'ultrasons ou par des moyens similaires, l'appareil de contrôle était guidé antérieurement par des éléments de guidage s'appliquant à la surface du tube. Il est connu aussi de transporter la matière à contrôler, par exemple des tubes, à travers l'appareil de contrôle, dans des guides fixes sans que l'appareil When testing tubes, for example for measuring the wall thickness and / or the detection of defects by means of ultrasound or similar means, the control apparatus was previously guided by guiding elements applying to the surface of the tube. It is also known to transport the control material, for example tubes, through the control apparatus, into fixed guides without the apparatus
de contrôle soit guidé.control is guided.
L'inconvénient du procédé connu est que par les contacts avec la surface, il se produit une forte usure The disadvantage of the known method is that by the contacts with the surface, a high wear occurs

Dos modes d'exécution possibles d'un dispositif selon l'invention sont représentés schématiquement par les dessins annexés sur lesquels: La figure 1 est une coupe d'un appareil d'essai comportant deux capteurs et huit sondes; La figure 2 est une coupe d'un appareil d'essai Possible embodiments of a device according to the invention are shown diagrammatically in the accompanying drawings, in which: FIG. 1 is a cross-section of a test apparatus comprising two sensors and eight probes; Figure 2 is a section of a test apparatus
comportant un guide annulaire pour les capteurs. having an annular guide for the sensors.
Comme on peut le voir par la figure 1, le tube à contr 8 ler est entouré d'un cadre annulaire 1 dans lequel sont disposés, d'une part,au moins deux capteurs 2, d'autre part au moins une sonde 6 pouvant être approchée Les capteurs 2 et les sondes 6 sont dirigés concentriquement sur la surface 3 du tube, les capteurs 2 étant également disposes de façon réglable A l'aide d'un dispositif de réglage 4 entrainé hydrauliquement, pneumatiquement ou par moteur électrique, le cadre 1 est déplacé et a l'aide d'un régulateur 5, relié aux capteurs 2, il est commandé en direction horizontale As can be seen in FIG. 1, the control tube 8 is surrounded by an annular frame 1 in which at least two sensors 2, on the other hand at least one sensor 6, are arranged on the one hand. The sensors 2 and the probes 6 are concentrically directed on the surface 3 of the tube, the sensors 2 being also arranged in an adjustable manner With the aid of a control device 4 driven hydraulically, pneumatically or by electric motor, the frame 1 is moved and using a regulator 5, connected to the sensors 2, it is controlled in the horizontal direction

Le mode de fonctionnement du dispositif est le suivants À l'aide du dispositif de réglage 4 * on amène le centre du cadre 1 au milieu du tube à contr 8 ler, avant le début du processus de contrôle À l'aide du dispositif d'approche 8, on règle les sondes au diamètre du tube à contr 8 ler Une fois que le tube a été introduit dans l'appareil, on détermine avec les capteurs 2 la position exacte de la surface du tube Par l'intermédiaire du régulateur 5 et du dispositif de réglage 4, on déplace le cadre de façon telleque la distance de toutes les sondes à la surface du tube soit égale et que lorsque le centre du tube s'éloigne du centre du cadre 1, celui-ci soit guidé de façon telletque la distance de The operating mode of the device is as follows. Using the adjustment device 4 *, the center of the frame 1 is brought to the center of the tube to be controlled, before the start of the control process. approach 8, the probes are adjusted to the diameter of the tube to be controlled Once the tube has been introduced into the apparatus, the sensors 2 determine the exact position of the surface of the tube via the regulator 5 and of the adjusting device 4, the frame is moved in such a way that the distance of all the probes on the surface of the tube is equal and that when the center of the tube moves away from the center of the frame 1, the latter is guided in such a manner that the distance of
toutes les sondes 6 soit maintenue constante. all the probes 6 is kept constant.
