APPRATUS AND METHOD FOR REMOVING A WALL PORTION FROM A WALL OF A TUBULAR MEMBER
Apparatus and method for removing a wall portion (180) from a wall of a tubular member (50). The wall portion (180) is connected to the wall of the tubular member by a pair of ligatures (210), which remain after use of a suitable cutting tool. The apparatus has a probe body (170) insertable into the...

| description | Apparatus and method for removing a wall portion (180) from a wall of a tubular member (50). The wall portion (180) is connected to the wall of the tubular member by a pair of ligatures (210), which remain after use of a suitable cutting tool. The apparatus has a probe body (170) insertable into the tubular member (50), which probe body includes an expandable bladder (230) for pushing the distal end portion (194) of the wall portion (180) in order to pivot the wall portion about the ligatures (210). After the wall portion pivots, a cup-shaped retainer (320) is moved upwardly to surround the proximal end portion (196) of the wall portion. A movable elongate mandrel (270) engages the proximal end portion of the wall portion. A hydraulic or pneumatic cylinder (390) downwardly moves the mandrel (270) in order to intimately engage the mandrel with the proximal end portion of the wall portion and downwardly displace the wall portion, such that the ligatures are severed. As the wall portion (180) is downwardly displaced, it is drawn into the retainer (320). As the wall portion (180) is drawn into the retainer (320), it is gripped between the retainer (320) and the mandrel (270). The probe body (170) is then removed from the tubular member.
L'invention se rapporte à un appareil et à un procédé d'enlèvement d'une partie (180) d'une paroi d'un élément tubulaire (50). La partie (180) de paroi est raccordée à la paroi par une paire de ligatures (210) qui restent après utilisation d'un outil de coupe approprié. L'appareil possède un corps (170) de sonde pouvant s'isérer dans l'élément tubulaire (50), le corps de sonde comprenant une vessie extensible (230) qui pousse la partie terminale distale (194) de la partie (180) de paroi afin de faire pivoter cette dernière autour des ligatures (210). Après pivotement de la partie de paroi, un élément de retenue en U (320) se déplace vers le haut pour entourer la partie terminale proximale (196) de la partie de paroi. Un mandrin allongé mobile (270) vient en contact avec la partie terminale proximale de la partie de paroi. Un cylindre hydraulique ou pneumatique (390) déplace vers le bas le mandrin (270) afin que ce dernier vienne en contact étroit avec la partie terminale proximale de la partie de paroi et afin de déplacer vers le bas la partie de paroi de sorte que les ligatures soient séparées. Lorsque la partie (180) de paroi se déplace vers le bas, elle s'enfonce dans l'élément de retenue (320), et lorsqu'elle est enfoncée d |
