    摘要： A threaded tubular connection comprises a male tubular element comprising a male threaded portion and a female tubular element comprising a female threaded portion which cooperates by screwing with the male threaded portion.
    In accordance with the invention, the threaded connection comprises at least one transfer zone which can transfer bending loads between said elements and which is axially spaced from said threaded portions, in which the male and female elements have an undulating surface and a smooth surface facing each other, the undulating surface (5) defining a series of rounded annular ribs (7) which come into contact with the smooth surface with a radial interference fit.
    Application to production strings for hydrocarbon wells.

    摘要： A threaded joint for steel pipes comprising a pin 1 having a tapered male thread 11, a tapered sealing surface 13, and an end shoulder surface 14 and a box 2 having correspondingly a tapered female thread 21, a tapered sealing surface 23, and a shoulder surface 24 which is capable of easy tightening and has improved air tightness by the sealing surfaces is arranged such that the pin and the box each have a noncontacting region B where the peripheral surfaces of the pin and the box do not contact each other between the sealing surfaces 13, 23 and the shoulder surfaces 14 and 24. At least a portion of the noncontacting region of the pin adjoining the end of the pin is a tapered surface portion 18 having substantially the same angle of slope as the tapered sealing surface 13, and the noncontacting region of the box is a substantially cylindrical surface.

    摘要： Radial interference between the male (3b) and female (4b) threadings operates between stabbing flanks (31, 36) inclined at about 27 with respect to the axis of the threadings, wherein the mutual contacting surfaces are radially spaced from the root of the male threading (32), which is defined by a concave rounded portion. Thus micro­-cracks caused by friction between these surfaces during relative movements of the male and female threaded elements are not affected by tensile stresses moving along the, envelope (E) of the male thread root (32), improving the fatigue resistance of the connection. Application to hydrocarbon wells connected to offshore platforms.

    摘要： The invention concerns a male threaded joint (1) tipped with a male lip (18)having a male seating face (13) and a male stop (14) transverse surface (16) proximate to the male seating face; and a female threaded element (21) comprising, for co-operation with the corresponding means of the male threaded element a female seating face (23) and a female stop transverse surface provided on a female shoulder and proximate to the female seating face. The annular female shoulder zone (24) which is subjected to axial compression forces resulting from the pressure of the male (16) and female (26) stop surfaces have an inner peripheral surface (27) whereof the diameter (IDB) is at least locally proximate to said female stop surface (26) smaller than the diameter (IDP) of the inner peripheral surface (17) of the male lip (18), the ratio R of said two diameters (IDB/IDP) being less than 1 but not less than 0.9.
