Title
(EN) A COUPLING
(FR) ACCOUPLEMENT
Abstract
(EN)
A coupling assembly for elongate elements (1, 2) comprises a pin member (5) and a box member (6), said pin and box members having complementary and respective frusto- conical pin and box mating surfaces (12, 13). A bore (9; 9') has as a first opening a port (9a) configured for connection to an injection fluid reservoir (10) and a second opening (9b) penetrating the pin mating surface (12) or the box mating surface (13). The surfaces (12, 13) may be plain surfaces without helical threads or other pronounced protrusions configured for mating engagement, but comprise a textured finish in order to augment static friction between the surfaces (12, 13) when the surfaces are connected. The pin surface may comprise a plurality of pin protruding portions (181-n) separated by pin recessed portions (191-n), and the box surface (13) comprise a plurality of box protruding portions (201-n) separated by box recessed portions (211-n). The pin protruding portions (18n) are shaped and dimensioned to fit into a designated box recessed portion (2n), and the box protruding portions (20n) are shaped and dimensioned to fit into a designated pin recessed portion (19n).
(FR)
L'invention concerne un ensemble d'accouplement pour des éléments allongés (1, 2), ledit ensemble comprenant un élément de broche (5) et un élément de boîte (6), lesdits éléments de broche et de boîte ayant des surfaces de contact de broche et de boîte tronconiques complémentaires et respectives (12, 13). Un alésage (9, 9') a pour première ouverture (9a) un orifice conçu pour être raccordé à un réservoir de fluide d'injection (10), et une seconde ouverture (9b) pénétrant dans la surface de contact de broche (12) ou dans la surface de contact de boîte (13). Les surfaces (12, 13) peuvent être des surfaces lisses sans filets hélicoïdaux ou autres saillies prononcées, conçues pour une mise en prise homologue, mais elles comprennent une finition texturée afin d'augmenter le frottement statique entre les surfaces (12, 13) lorsque les surfaces sont raccordées. La surface de broche peut comprendre une pluralité de parties de broche en saillie (181-n) séparées par des parties de broche montées en retrait (191-n), et la surface de boîte (13) comprend une pluralité de parties de boîte en saillie (201-n) séparées par des parties de boîte montées en retrait (211-n). Les parties de broche en saillie (18n) sont formées et dimensionnées de manière à s'ajuster dans une partie de boîte montée en retrait désignée (2n), et les parties de boîte en saillie (20n) sont formées et dimensionnées de manière à s'ajuster dans une partie de broche montée en retrait désignée (19n).
