Title
(EN) PACKER END RING WITH DEVICE FOR GRIPPING BASE PIPE
(FR) ANNEAU D'EXTRÉMITÉ DE GARNITURE ÉTANCHE AVEC DISPOSITIF DE PRÉHENSION POUR TUYAU DE BASE
Abstract
(EN)
A packer can include an end ring positioned proximate a seal element on a base pipe, and a gripping device which is compressed radially inward by a surface formed in the end ring, the surface encircling the base pipe. A method of constructing a packer can include positioning an end ring on a base pipe proximate a seal element, and radially compressing a gripping device in the end ring, so that the gripping device grips the base pipe, radial compression of the gripping device resulting from longitudinal displacement of the gripping device relative to the end ring.
(FR)
L'invention concerne une garniture étanche comprenant un anneau d'extrémité positionné à proximité d'un joint d'étanchéité sur un tuyau de base et un dispositif de préhension comprimé radialement vers l'intérieur par une surface formée dans l'anneau d'extrémité, la surface encerclant le tuyau de base. Un procédé de construction d'une garniture étanche peut inclure le positionnement d'un anneau d'extrémité sur un tuyau de base à proximité d'un joint d'étanchéité et la compression radiale d'un dispositif de préhension dans l'anneau d'extrémité, de sorte que le dispositif de préhension soit accroché au tuyau de base, la compression radiale du dispositif de préhension résultant du déplacement longitudinal du dispositif de préhension par rapport à l'anneau d'extrémité.
