  • Threaded tubular connection with progressive axial thread interference
    Publication number: 20060261595
    Abstract: A threaded connection includes at least one contact zone axially separated from threadings in which a male and female elements are in sealed contact via bearing surfaces respectively constituted by a cambered surface and by a tapered surface. Such a contact zone ensures a seal against fluids despite positional inaccuracies in the male and female elements at the end of makeup, due to the geometrical characteristics of the threadings. Such a threaded connection can find, as an example, application to oil and gas wells.
