A tool joint for a pipe string, comprises a box end having a female threaded section proximate a longitudinal end of a pipe segment. A threaded section is formed on an interior wall of the pipe segment proximate a base of the female threaded section. The threaded section has formed therein at least one locking bore for receiving a locking pin. The at least one receiving bore is oval shaped and elongated in a longitudinal direction of the pipe segment. A shoulder sleeve has on its exterior surface threads for engaging the threaded section, and at least one pin bore through a wall of the shoulder sleeve. At least one locking pin is passed through the pin bore to engage the at least one locking bore when the at least one pin bore is rotationally and longitudinally aligned with the at least one locking bore.[French]
L'invention concerne un raccord d'outil pour un train de tiges, qui comprend une extrémité femelle ayant une section filetée femelle à proximité d'une extrémité longitudinale d'un segment de tige. Une section filetée est formée sur une paroi intérieure du segment de tige à proximité d'une base de la section filetée femelle. La section filetée possède, formé en son sein, au moins un alésage de verrouillage pour la réception d'une goupille de verrouillage. L'au moins un alésage de réception est de forme ovale et allongé dans une direction longitudinale du segment de tige. Un manchon d'épaulement possède, sur sa surface extérieure, des filets pour une mise en prise avec la section filetée, et au moins un alésage de goupille à travers une paroi du manchon d'épaulement. Au moins une goupille de verrouillage est passée à travers l'alésage de goupille pour se mettre en prise avec l'au moins un alésage de verrouillage lorsque l'au moins un alésage de goupille est aligné en rotation et longitudinalement avec l'au moins un alésage de verrouillage.
