Definitions

  • the invention relates to a method of manufacturing a sheet ferrule, in particular for a container for storing a cryogenic fluid formed by a reservoir housed in said ferrule and separated from the latter by an interwall maintained under vacuum and at minus a heating coil placed in said interwall.
  • Cryogenic fluid storage containers generally consist of an internal reservoir and an external envelope, both metallic separated by a sealed volume maintained under vacuum and called "inter-wall”.
  • the outer envelopes of these containers are generally formed of a cylindrical sheet metal body closed at each of its ends by a bottom and must be provided to withstand atmospheric pressure as well as mechanical stresses. This is achieved either by giving the sheet a sufficient uniform thickness, or by providing the envelope with uniformly distributed stiffening members.
  • the present invention aims to overcome the aforementioned drawbacks and, therefore, to achieve a shell capable of withstanding significant stresses, whether due to atmospheric pressure or mechanical requirements, and much lighter than those obtained by prior techniques.
  • the invention realizes the deformation, therefore the stiffening of the cylinder, in the serpentine medium-due, and simultaneously incorporates the latter, the assembly thus formed forming the ferrule.
  • This has the advantage of adding the inertias of the deformed cylinder and the coil while taking advantage of the stiffening provided by the work hardening of the metal. As a result, it is possible to use a sheet which is thinner than those which have been used until now.
  • the tube and the cylinder it is preferable to fix them to each other after said injection.
  • they are provided, on their facing walls, with a layer of a tinning product, and the aforementioned fixing is carried out by brazing. We thus also obtains a ferrule ensuring the best buckling resistance conditions.
  • the invention also relates to a ferrule for a cryogenic fluid storage container obtained by a method as defined above.
  • the wall of this ferrule has a helical imprint projecting outwards and the coil is fixed to said wall in coincidence with said imprint.
  • the object of the invention is to obtain a significant stiffening of the shell by using only the metal which constitutes it and by deforming this metal to give it the desired stiffening function, a solution which has the advantage of eliminating the addition of reported stiffeners and allow the use of a thinner sheet than for previously known ferrules. In addition, this deformation results in work hardening of the metal which appreciably increases the stiffening.
  • the aforementioned deformation is carried out using the heating coil (s) and incorporating them into the shell, which makes it possible to add the inertias of the deformed and hardened shell and of the coil (s).
  • FIGS. 1 and 2 show two of the main stages in the manufacture of the ferrule according to the invention, which consists essentially of the tube 1 and of the cylinder 2.
  • the tube 1 is made of a sufficiently malleable material, generally copper, and has a cross section S 1 of flattened shape, that is to say that its facing walls are almost contiguous, leaving between them only a very small space just sufficient for the admission of a hydraulic fluid under high pressure.
  • This tube can be obtained from an ordinary tube of circular cross section which is flattened by stretching.
  • Such a tube of circular cross section having a wall thickness e thus leads, after drawing, to a flattened tube having a thickness 2e.
  • the tinning of the outer wall of the tube 1 is then carried out, while it is in flattened form, by passing it through an appropriate bath.
  • the tube 1, thus covered with a layer of tinning product, is wound on an extensible mandrel schematically indicated in M, so as to constitute a helix of pitch p and of external diameter D H.
  • the cylinder 2 is formed from a sheet of thickness e T made of a metal with high mechanical resistance and high resistance to corrosion, generally made of stainless steel. Is deposited on this sheet, while it is flat, a tinning product disposed in strips 3 corresponding to the developed of the propeller of pitch p above. The sheet metal thus pre-tinned is then rolled to obtain a cylinder of circular cross section, the two edges of which are welded according to a generatrix.
  • the internal and external diameters of cylinder 2 thus obtained have been designated by D CI and D CE .
  • the assembly constituted by the tube and the ferrule 4 is then separated from the mandrel M after having made them provisionally integral with one another (for example by brazing the two ends 1 a and 1 b to said ferrule 4) and passes the said assembly to the oven at about 220 ° C to cause the tinning material to melt and thus ensure brazing. Then the rinsing of the shell thus obtained is rinsed.
  • the ferrule of Figure 3 made from a stainless steel cylinder, comprises two copper helical coils 7 and 8, the two ends are indicated by 7a, 7b and 8a, 8b and constitute an element of use or withdrawal and a pressurizing element respectively. These two coils were obtained from two separate tubes which were wound on the same mandrel, simultaneously or separately, but with the same pitch. In the finished shell, they are arranged one after the other and are housed in the interwall 9 which separates the shell itself from the internal reservoir 10.
  • the ferrule of Figures 4 and 5 is made from a single copper tube 12 whose ends are designated by 12a and 12b which, after brazing was sectioned at two points S 1 and S 2 of one of its turns. Then connected to the two points S 1 and S 2 two straight elements 13 and 14, the ends of which are designated by 13a and 14a respectively. There is thus obtained a coil 12 - 13 for use and a coil 12 - 14 for pressurizing, as in FIG. 3.
  • This embodiment has the advantage of simplifying the various manufacturing operations, in particular the winding. It should be noted that the sectioning of the coil at points S 1 and S 2 is preferably carried out after the expansion operation.
  • the tube After flattening, the tube is coated, on its external wall, with a layer of tinning product by passage through a bath comprising a mixture of 60% lead and 40% tin.
  • the tube is wound on the mandrel according to a helix with a pitch of 80 mm which, of course, corresponds to that of the tinning of the cylinder.
  • the tube After extension of the mandrel, the tube is expanded by connecting it to a hydraulic pressurization device which makes a liquid penetrate into it under a pressure of 500 bars.
  • the two ends of the coils are fixed to the sheet, preferably by silver brazing, and the entire mandrel is removed. It is then possible, in the case where it is desired to obtain a ferrule of the type shown in FIG. 5, proceed to the connection of the rectilinear elements necessary for this purpose. The ferrule is then placed in a brazing oven to bring it to a temperature of approximately 220 ° C. Finally, the ferrule is rinsed to remove foreign bodies, soldering residues or the like.
  • an unreinforced shell having substantially the same dimensional characteristics that is to say the same diameter (508 mm) and the same length (for example 1 m) must, for have an outfit equivalent to buckling and an equivalent impact resistance, be made from a stainless steel sheet of the same type as above but having a thickness of 2.5 mm.
  • the brazing material could be deposited on the cylinder and on the tube after the pressurized expansion operation.
  • the process can be very simply adapted to the manufacture of any ferrule provided with an internal coil, and even with an external coil. In the latter case, it suffices to wind the copper tube or tubes in a radially contractible hollow mandrel.
