An interconnection for oil field tubular goods operates in a self sealing manner in response to internal pressures which might otherwise cause leakage through couplings or joints. Each coupling sleeve includes an interior fulcrum ring fitted between the nose ends of the tubing or casing, and centrally engaging a fulcrum seating zone centered in the sleeve. Internal pressures tend to bend the ends of the fulcrum ring outwardly toward clearance or relief spans on each side of the fulcrum zone. This deflection increases the contact force and enhances the metal-to-metal seal between the end faces of the fulcrum ring and the pin end faces.

Selon la présente invention, un couplage pour matériels tubulaires de champs de pétrole fonctionne de manière autohermétique suite à des pressions internes qui peuvent provoquer une fuite à travers des couplages ou des joints. Chaque manchon de couplage comporte un anneau de rotation interne qui est fixé entre les extrémités de partie avant du tubage ou du cuvelage et qui rentre en contact centralement avec une zone d'appui de rotation centrée dans le manchon. Des pressions internes tendent à courber les extrémités de l'anneau de rotation vers l'extérieur en direction d'intervalles de jeu ou de décharge au niveau de chaque côté de la zone de rotation. Cette déviation permet d'augmenter la force de contact et d'améliorer le joint métal-métal entre les faces d'extrémité de l'anneau de rotation et les faces d'extrémité mâle d'un joint de tige.
