Abstract

L'invention concerne un système d'échantillonnage destiné à obtenir un échantillon à partir de la paroi intérieure d'un tube, lequel outil comprend des premier et second sous-ensembles de couteaux reliés en fonctionnement à un arbre. Des premier et second actionneurs déplacent les premier et second sous-ensembles de couteaux entre une position rétractée et une position déployée au fur et à mesure que l'arbre se déplace. L'invention concerne également une soupape mettant sélectivement en contact fluide un orifice d'éjection situé dans un des premier et second sous-ensembles de couteaux avec une source de fluide de purge. La soupape déverse le fluide de purge par l'orifice d'éjection sur la paroi intérieure du tube durant le découpage d'une partie de la paroi.
