发明名称 Method for producing a threaded tubular connection sealed to the outside
摘要 In a threaded connection with tapered male and female threads, an annular housing is provided in the vicinity of the free end of the female element, which housing receives a portion of a deformable sealing ring, which is radially compressed, while a retaining lip of the ring is immobilized in a further annular housing of the female element by a rib on the male element. Such a connection may find particular application for connecting pipes for hydrocarbon wells.
