Patent

CA 2448085

A method is provided of radially expanding a connector (24) for interconnecting a first tube (18) to a second tube (20), the connector including a pin member (26) extending into a box member (28). The pin and box members have cooperating support means (26, 28) arranged to support the pin member so as to prevent radially inward movement of said end portion of the pin member relative to the box member. The method comprises radially expanding the connector (24), and supporting the pin member so as to prevent radially inward movement of said end portion of the pin member relative to the box member.

L'invention concerne un procédé de fabrication d'un raccord expansible radialement (24) destiné à raccorder entre eux un premier tube (18) et un second tube (20). Ledit raccord comprend un premier élément tige (26) s'étendant dans un élément boîtier (28). Les éléments tige et boîtier sont dotés de moyen de soutien coopérants (26, 28) conçus pour soutenir la tige, de sorte qu'elle empêche le mouvement radial vers l'intérieur de ladite partie d'extrémité par rapport au boîtier. Le procédé de l'invention consiste à induire l'expansion radiale du raccord (24), et à soutenir la broche, de manière que le mouvement radial vers l'intérieur de ladite partie d'extrémité de la broche par rapport au boîtier soit empêché.
