摘要： To produce a sealing contact between male and female threaded elements, a contact zone is provided, located between male and female threading portions separated from each other in an axial direction. The male and female elements have respective cylindrical portions that extend over the entire length of the contact zone. After expansion, a sealing contact is established between surfaces in two annular areas by a radial interference fit.

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 (L1) 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 (SI3) 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： The invention relates to an assembly comprising two symmetrically-disposed expandable threaded tubular joints, each of said joints consisting of: (i) a male tubular element (EM1, EM2) which is placed at one end of a tube (T1, T2) and which is equipped with (a) a male thread (FM), (b) a first annular lip (L1) having a first axially abutting surface (SB 1), a first inner surface (SI1) and a first outer surface (SE1), and (c) a second abutting surface (SB2); and (ii) a female tubular element (EF1, EF2) which is equipped with (a) a female thread (FF), (b) a second annular lip (L2) having a third abutting surface (SB3), a second outer surface (SE2) and a second inner surface (SI2), and (c) a third inner surface (SI3) and a fourth axially abutting surface (SB4) which, together with the second outer surface (SE2), defines an annular housing (LO) homologous to the corresponding first lip (L1). According to the invention, the two female tubular elements (EF1, EF2) form two opposing ends of a female/female-type sleeve (M), said ends being separated by a central part (PCM) which initially comprises an annular zone (G2) having an initial thinned thickness that is selected such that the thickness of the sleeve (M) at the aforementioned zone (G2) is greater than or equal to the product of the section of a running part of the tubes, at the ends of which the male tubular elements are formed, owing to the effectiveness of the joint. Moreover, the male and female tubular elements are arranged such that every second abutting surface (SB2) rests against the corresponding third abutting surface (SB3) after screwing and prior to diametral expansion in the plastic deformation region with the aid of an axially-movable expansion tool.

摘要： The invention relates to a sealed tubular joint, initially comprising a first male tubular element (EM), with a male thread (FM), a first annular lip (L1), with a first axial abutting surface (SB1), a first internal surface (SI1), a section of a first external surface (SE1), a second abutting surface (SB2) and a second female tubular element (EF), with a female thread (FF), matching the male thread (FM), a second annular lip (L2), with a third abutting surface (SB3), a second external surface (SE2), arranged to face the first internal surface (SI1), a second internal surface (SI2) and a fourth axial abutting surface (SB4), supporting the first abutting surface (SB1) and defining, in particular with the second external surface (SE2), an annular housing (LO), matching the first lip (L1). The second (SB2) and third (SB3) abutting surfaces are initially conical with angles of inclination which are effectively identical and which permit, on screwing, the contact of the second abutting surface (SB2) against the third abutting surface (SB3), generating a first radial locking and sealing contact of the first internal surface (SI1) or external surface (SE1) against the second external surface (SE2), or the third internal surface (SI3), and then, with a diametrical expansion in the region of the plastic deformation by means of an axially-displaceable expansion tool, the first external surface (SE1) and the third internal surface (SI3) are forced to locally define a second locking and sealing contact.

摘要： A threaded connection includes first and second tubular components, each including a respective male and female end. The male and female ends each include at least one threaded zone and finish in a terminal surface. The male threaded zone includes a first portion in which a width of teeth, CWTp, increases from a value CWTpmin corresponding to a width of a tooth closest to the terminal surface of the male end to a value CWTpmax corresponding to a width of a tooth furthest from the terminal surface. A width of teeth CWTb of the female threaded zone decreases from a value CWTbmax corresponding to a width of a tooth furthest from the terminal surface of the female end to a value CWTbmin corresponding to a width of a tooth closest to the terminal surface. The threaded zones cooperate in accordance with a self-locking make-up, with CWTpmin/CWTbmax≥0.2 and CWTbmin/CWTpmax≤CWTpmin/CWTbmax.

The first component including a male threaded end, the second component including a female threaded end, and both the male and female threaded ends finishing in a terminal surface. The threaded zones include, over a portion defined as in a self-locking make-up, threads, which before the self-locking make-up and when viewed in a longitudinal section passing through the axis of revolution of the first and second components, each include: a thread crest, a thread root, a load flank, and a stabbing flank. A width of the thread crests of each component reducing in a direction of the terminal surface of the component under consideration, while a width of the thread roots increases. A lead of the male stabbing flanks and/or load flanks is different from a lead of the female stabbing flanks and/or load flanks.
