CA 2688148

The invention relates to a device for the non-destructive testing of objects, particularly pipes in oil refineries, having a first positioning means (10) for positioning a collimator (1) comprising a radioactive radiation source (5) near an object (40) to be tested, and a second positioning means (20) for positioning a film carrier (21) near the object to be tested (40). The first positioning means (10) may be anchored or placed with a lower end on a substantially flat base surface, wherein the collimator (1) is attached to the opposite, upper end of the first positioning means (10). Before the exposure, the radiation source (5) may be guided towards the collimator (1) via a delivery tube (8) such that no radiation is able to be emitted from the device during the placement of the first positioning means (10).

L'invention concerne un dispositif de contrôle non destructif d'objets, en particulier de tuyaux dans des raffineries de pétrole, ce dispositif comprenant un premier moyen de positionnement (10) pour positionner un collimateur (1) pourvu d'une source de rayonnement (5) radioactive auprès d'un objet à contrôler (40), ainsi qu'un deuxième moyen de positionnement (20) pour positionner un support de film (21) auprès de l'objet à contrôler (40). Le premier moyen de positionnement (10) peut être ancré ou posé sur une surface d'appui à son extrémité inférieure, le collimateur (1) étant placé à l'extrémité supérieure opposée du premier moyen de positionnement (10). La source de rayonnement (5) peut être acheminée jusqu'au collimateur (1) par un tuyau d'amenée (8) avant un enregistrement de sorte qu'aucun rayonnement ne puisse sortir du dispositif pendant la mise en place du premier moyen de positionnement (10).
