- tubular threaded joints are known in which the male element is formed at the end of a very long tube and the female element at the end of another very long tube or of a shorter tubular component such as a connection sleeve, these joints making it possible to assemble end to end a multiplicity of tubes to form a column, in particular in hydrocarbon wells, where this column is used for the exploitation of hydrocarbons (column of tubes production) or to maintain the land (column of casing tubes).
- EP 0 488 912 A describes a threaded joint having a frustoconical metallic sealing surface disposed at the end of the male threaded element and a corresponding metallic sealing surface provided on the female threaded element.
- This threaded joint has excellent sealing characteristics with regard to fluids circulating both inside and outside the joint. However, fluid can seep from the outside onto all or part of the threads and cause corrosion risks when the fluid is corrosive.
- the object of the invention is to eliminate the above drawbacks, and therefore to allow the production of a tubular threaded joint particularly suitable for rising underwater tubular columns subjected to cyclic stresses.
- the invention is particularly aimed at producing a tubular threaded joint whose male and female elements are very close to those commonly used for columns of casing tubes, in particular as regards their thickness, and therefore inexpensive to produce.
- the invention relates in particular to a method of the kind defined in the introduction, and provides that a deformable sealing ring is placed around said male thread, the free end of the male element is engaged, and the male thread is screwed in the female thread, said sealing ring, during screwing, being pushed along the male element by said first shoulder, driven in rotation by the female element and compressed radially between the male thread, in which it is printed, and said peripheral surface of the housing.
- the terms “tightness” and “tight contact” here refer to measures intended not necessarily to prevent - any access - of fluid - in contact with the threads, - but at least to limit such access so as to practically prevent renewal of the fluid and consequently significant corrosion.
- the sealing ring is made of a material chosen from synthetic materials, malleable metals and composite materials.
- the sealing ring is made of a material having a low coefficient of friction with the material of the male element.
- the sealing ring is made of polytetrafluoroethylene, loaded or not.
- the male thread comprises, opposite the free end of the male element, so-called fading threads, the radial height of which generally decreases from a nominal value to a zero value, and the sealing ring is in tight contact with said fading nets over at least part of its axial length.
- the sealing ring is in contact with said fading threads over its entire axial length.
- the sealing ring is placed around the said vanishing nets.
- the male element is machined, over at least a fraction of the axial length of the fainting threads, to a constant diameter greater than the diameter of the bottoms of the threads concerned.
- the sealing ring is placed around the region of the machined male element, at constant diameter.
- - Said housing has a second shoulder turned axially towards the first shoulder and of a minimum diameter greater than that of the first shoulder, a part of the volume of the sealing ring being compressed axially between the first and second shoulders.
- the first shoulder or at least one of the first and second shoulders, is inclined relative to the axis of the threads.
- - Said housing opens at the free end of the female element by a flare.
- the male element has, near its free end, an axial abutment surface capable of cooperating with an axial abutment surface of the female element to limit the screwing.
- Additional sealing means are provided to prevent any communication of fluid between the interior of the tubular joint and the zone of cooperation of the threads.
- the sealing ring is fitted with clamping on the male thread.
- the sealing ring is placed around the male thread at a temperature such that its inside diameter is greater than the outside diameter of the underlying threads, its inside diameter being less than the outside diameter of the threads underlying the temperature room.
- the sealing ring is an O-ring of rectangular section elongated in the axial direction.
- the outside diameter of the sealing ring after its installation around the male thread is slightly less than the minimum radius of the peripheral surface of said housing.
- the invention also relates to a tubular threaded joint as can be obtained by the method as defined above, comprising a male tubular element comprising a conical male thread, a female tubular element comprising a conical female thread which cooperates by screwing with the male thread, and a deformable sealing ring interposed between the male and female elements so as to oppose the communication of fluid between the outside of the tubular joint and the cooperation zone of said threads, the sealing ring being in sealed contact * with the male thread, and the female element having an annular housing for receiving the sealing ring, disposed axially between its free end and the female thread and limited axially by a first turned shoulder towards said free end, the sealing ring pressing axially against said first shoulder and being in sealed contact e with the peripheral surface of the housing.
- the tubular threaded joint according to the invention may include at least some of the following features:
- the first and second shoulders are respectively perpendicular to the axis of the threads and inclined relative thereto.
- the housing has a constantly increasing diameter towards the free end of the female element, its peripheral wall being strongly inclined relative to the axis of the threads opposite said free end to form a shoulder suitable for pushing the sealing ring when screwing of the threaded elements, and its angle then decreasing gradually.

- the diameter of the outer surface 31, and therefore the radial thickness of the ring 30, are chosen so as to allow the introduction of the ring into the housing provided for this purpose in the female element, during screwing, and sealed contact of the ring with male and female elements at the end of screwing , as will be described later.
- the external surface 19 of the tube 101 generally having a certain ovalization, it is advantageous, as shown in FIG. 3, to eliminate or reduce this ovalization, over at least part of the length of the threaded part 13 with vanishing threads, by machining according to a cylindrical surface of revolution.
- two cylindrical machining surfaces are provided.
- a first cylindrical surface 41 of smaller diameter which begins in the threaded part 11 and extends mainly in the threaded part 13, and a second cylindrical surface 43 of larger diameter is connected to the surface 41 according to a concave arc profile 45 and extends to the unthreaded part of the tube 101, where it is connected to the external surface 19 according to a concave arc profile 47.
- the diameter of the surface 41 and the axial position of the profile 45 are chosen so that the machining does not reach the envelope 15 of the thread bottoms.

This inclination is strong in the vicinity of the wall 16 to form a shoulder 27 which pushes the sealing ring when the threaded elements are screwed.
- the initial ring 30 can here again have the rectangular cross section illustrated in FIG. 2.
- the housing has an inlet chamfer 21 and a shoulder 25 similar to those of Figure 3, interconnected by a cylindrical surface 28.
- the original ring forming the ring seal 35 no longer has a rectangular profile, but has, beyond the end face 34 which comes to bear on the shoulder 25, an appendage 36 in the form of a thin lip which covers the cylindrical surface 16 of the female element and enters the groove 18, thus making an attachment of the ring on the female element.
