LIQUID- AND GAS-TIGHT THREADED TUBULAR CONNECTION |
摘要 |
A liquid and gas tight threaded tubular connection includes 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. The first and second axial abutment surfaces have the same axial half-sections, the inclination of which varies progressively in the radial direction. |
