    摘要： A threaded tubular connection which is leak-proof for internal and external successive pressure loads with comprises a male element (11) and a female element (12). At least one of the male or female elements (11, 12) comprises a lip (14, 16) between the threading (13, 15) and the free end of the element (17, 18). The lip (16) comprises a first zone (20) with a peripheral surface turned towards the other element (11) on which a first metallic sealing surface (22) is disposed which can be radially interference fitted against a corresponding second metallic sealing surface (23) disposed on the other element (11). The lip (16) has a second zone (21) located axially between said first zone (20) and the corresponding threading (15). The radial stiffness of the second zone (21) is less than that of the first zone (20) and that of a third zone adjacent to the second zone (21) in the direction of the threading (15), and zone (21) can be radially deformed by a pressure which is exerted thereon.

    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： The invention relates to an expandable tubular joint comprising: (i) a male tubular element (EM) which is equipped with a male thread (FM), a first annular lip (LI) having a first axially abutting surface (SB1), a first inner surface (SI1) and a first outer surface (SE1), and a second abutting surface (SB2); and (ii) a female tubular element (EF) which is equipped with a female thread (FF), a second annular lip (L2) having a third abutting surface (SB3), a second outer surface (SE2) and a second inner surface (SI2), and a third inner surface (S13) and a fourth axially abutting surface (SB4) which, together with the second outer surface (SE2), defines a first annular housing (LO) homologous to the first lip (L1). According to the invention, the male tubular element (EM) initially comprises a local annular added thickness (SA1) at a fourth inner surface (SI4) which projects out from the second abutting surface (SB2). The third inner surface (SI3) of the female tubular element (EF) comprises an annular groove (G1) which, after screwing, is placed at the first outer surface (SE1) and the annular added thickness (SA1). The male and female elements are shaped such that, after screwing, the first lip (L1) is housed in the annular housing (LO) and the second and third abutting surfaces rest against one another, in order to enable the formation of an annular shoulder (EP) at the first outer surface (SE1) during diametral expansion in the plastic deformation region, said shoulder having the shape of part of the groove (G1) and being in hermetic clamping contact therewith.

    摘要： A cap (10) comprising a female threading (11) matched with that (2) of a first element is made up onto the first male threaded element (1) of a component to be tested so as to compress a sealing ring (16) between metal surfaces (7, 15) of the first element and the cap, and a test pressure is established inside said component, the male element (1) having an annular lip (3) which is capable of deforming radially outwardly under the effect of said test pressure. Between the radially outward surface (6) of the lip (3) and the facing surface (19) of the cap, at the end of makeup there exists a clearance having a value (j) which has been selected sufficiently small so that, under the effect of the test pressure, the lip bears on said facing surface without undergoing plastic deformation. Application to tubular string accessories for hydrocarbon wells.

    摘要： A double shoulder drill stem connection for high torque applications includes a thread taper within a range between about 1.0 and 1.2 inch per foot. The thread form is characterized by a stab angle between about 35 and 42 degrees and a load angle between about 25 and 34 degrees and by a short thread height with elliptical roots and with crests having an angle which slopes in an opposite direction with respect to the joint centerline from the thread taper. A drill string includes a tool joint having different inner diameters for a substantial axial length to provide enhanced strength in the threaded portion of the joint.

    摘要： An apparatus for and a method of measuring an outer diameter of a worked portion at a pipe end, by which an outer diameter of an end of pipe of various sizes is rapidly and precisely measured; the apparatus comprising a main arm (1), a lower gauge head support arm (2), a bearing roller arm (3), an upper gauge head support arm (4), a presser roller arm (5), a position fixing metal fitting (6), a gauge head (14b) supported by the arm (2) to be movable horizontally and vertically, a gauge head (15b) supported by the arm (4) to be movable horizontally and vertically, and gauge heads (14a, 15a) which are movable vertically. An outer diameter of an article being measured is measured by the gauge heads while the article is rotatably held by rollers (10a, 10b, 11a, 11b) on the arms (3, 5). The measurement can be effected simultaneously at two locations in a lengthwise direction of the article being measured.
