发明名称 SEALED TUBULAR CONNECTION USED IN THE OIL INDUSTRY
摘要 The invention concerns a sealed threaded connection comprising a first and a second tubular component, each being provided with a respective male end (1) and female end (2), the male end (1) comprising, on its outer peripheral surface, at least one threaded zone (3), and at least one sealing surface (5,11) and finishing in a terminal surface (7) which is orientated transversely to the axis (10) of the connection, the female end (2) comprising, on its inner peripheral surface, at least one threaded zone (4) cooperating with the threaded zone (3) of the male end (1) by make up, the threaded zones (3, 4) being inclined in accordance with a conical generatrix (20) forming an angle of taper alpha; with the axis (10) of the connection, at least one sealing surface (6, 12) being positioned so as to cooperate with the at least one sealing surface (5, 11) of the male end (1) along a radially interfering contact zone, and finishing in a terminal surface (8) which is transversely orientated with respect to the axis (10) of the connection, the tangent at the contact zone of the sealing surface (5, 6; 11, 12) being inclined along a line (30) forming an angle beta; with the axis (10) of the threaded connection, characterized in that the inclination defined by the conical generatrix (20) relative to the threaded zones (3, 4) is in a direction opposite to the inclination defined by the tangent (30) at the contact zone of the sealing surface (5, 6; 11, 12).
