Abstract

Dans le mode préférentiel de réalisation, cette invention concerne un accouplement (12) de tubes filetés se connectant à une extrémité filetée conventionnelle (10) d'un tube de manière à réaliser une étanchéité améliorée contre une pression de fluide interne et contre une pression de fluide externe, comme cela est nécessaire dans un puits de pétrole ou de gaz. La forme de l'accouplement est telle que la pression de contact du filetage est plus grande au niveau des diamètres maximum (|6) et minimum (18) du contact de filetage qu'au niveau des points intermédiaires (18) le long du contact de filetage. Un joint (27) en plastique auxiliaire supportant les cycles thermiques est également prévu.
