Liquid and Gas Tight Threaded Tubular Connection |
摘要 |
A liquid and gas tight threaded tubular connection. A first axial abutment surface formed at the free end of an annular lip of a threaded male element and a second axial abutment surface formed at the end of a housing of a threaded female element have same axial half-sections, the inclination of which varies progressively in the radial direction. Such a configuration of the axial abutment surfaces optimizes radial thrust exerted on the end of the lip depending on its thickness, to obtain an increased radial interference between the respective sealing surfaces of both elements. Such a connection may find application to hydrocarbon wells, for example.
