Title (EN) MID-SEAL FOR EXPANDABLE CONNECTIONS
(FR) SCELLEMENT INTERMEDIAIRE POUR RACCORDEMENTS EXTENSIBLES
Abstract: front page image
(EN)An expandable tubular connection includes a pin member and a box member. The pin member includes a pin thread formed on a small step and a large step and a first seal surface formed between the small step and the large step. The box member includes a box thread formed on a small step and a large step and a second seal surface formed between the small step and the large step. The pin thread and the box thread are wedge threads. Upon a selected make-up of the pin member with the box member a selected gap exists between the first seal surface and the second seal surface. The gap is selected such that, when plastically radially expanded by a selected amount, a seal is formed between at least a portion of the first seal surface and the second seal surface.
(FR)L'invention concerne une raccordement tubulaire extensible qui comprend une broche et une boîte. La broche comprend un filetage de broche formé sur un petit échelon et un grand échelon et une première surface de scellement formée entre le petit échelon et le grand échelon. La boîte comprend un filetage de boîte formé sur un petit échelon et un grand échelon et une seconde surface de scellement formé entre le petit échelon et le grand échelon. Le filetage de broche et le filetage de boîte sont des filetages de coin. Dans un montage choisi de la broche avec la boîte, un espace choisi est formé entre la première surface de scellement et la seconde surface de scellement. L'espace est choisi de façon que, lorsqu'il est étendu radialement et plastiquement selon un taux choisi, un scellement est formé entre au moins une partie de la première surface de scellement et la seconde surface de scellement.
