Description

L'invention se rapporte à une citerne du type de celles utilisées pour le conditionnement de fluides à haute pression en vue de leur transport. The invention relates to a tank of the type used for the packaging of high pressure fluids for transport.

L'invention intéresse plus particulierement mais non exclusivement les conteneurs à citerne, c'est à dire les réceptacles agencés dans une structure de poutres rigides qui s 'étendent principalement selon les arêtes d'un parallélépipède rectangle et constituant en quelque sorte le support de la citerne. The invention concerns more particularly but not exclusively the tank containers, that is to say the receptacles arranged in a structure of rigid beams which extend mainly along the edges of a rectangular parallelepiped and constituting in a way the support of the tank.

Les dimensions de tels conteneurs font l'objet de normes internationales et à chaque taille de conteneur admissible pour son transport et sa manutention correspond une limite maximale de masse totale en charge. The dimensions of such containers are subject to international standards and each container size admissible for its transport and handling corresponds to a maximum limit of total laden mass.

Quant aux citernes, elles sont généralement cylindriques et l'épaisseur de leur paroi en acier est classiquement calculée pour leur permettre d'étre éprouvées pour une pression de 30 Bars. As for the tanks, they are generally cylindrical and the thickness of their steel wall is conventionally calculated to allow them to be tested for a pressure of 30 Bars.

Pour permettre à ces citernes de supporter des pressions d'épreuve dix fois supérieures sans changer leur diariétre extérieur, il faudrait évidemment augmenter 1'é3aisseur de leur paroi. To enable these tanks to withstand test pressures ten times greater without changing their outside diameter, it would obviously be necessary to increase the thickness of their wall.

Compte tenu du diamètre et de la forme cylindrique des citernes, cette épaisseur devrait être majorée dans des proportions tells que la masse à vide de la citerne seule avoisinerait voire depaserait la masse maximale en charge admissible pour le conteneur. Given the diameter and the cylindrical shape of the tanks, this thickness should be increased in such proportions that the empty mass of the tank alone would approach or even exceed the maximum permissible laden mass for the container.

Pour remédier à cet inconvénient, il est connu de répartir le volume de fluide transportable par le conteneur dit volume utile sur une pluralité de capacités cylindriques chacune de faible diametre par rapport à sa longueur. To overcome this drawback, it is known to distribute the volume of fluid transportable by the container called useful volume over a plurality of cylindrical capacities each of small diameter compared to its length.

Notamment pour des raisons de sécurite, les capacités doivent alors être indépendantes les unes des autres et, à cet effet, elles doivent chacune être pourvues d'un orifice de vidange et/ou de remplissage qui lui est propre et qui est placé sous le contrôle d'un organe particulier de controle du passage du fluide, l'ensemble de ces organes étant relié à un circuit commun de remplissage et/ou de vidange.  In particular for safety reasons, the capacities must then be independent of each other and, for this purpose, they must each be provided with its own drain and / or filling orifice and which is placed under control a particular member for controlling the passage of the fluid, all of these members being connected to a common filling and / or emptying circuit.

Compte tenu des qualités notamment mécaniques exigées, des organes de contrôle du passage du fluide, ceux-ci sont très onéreux, ce qui se répercute notablement sur le prix de l'installation de remplissage et/ou de vidange précitée et donc sur le prix du conteneur. Given the particular mechanical qualities required, the bodies for controlling the passage of the fluid, these are very expensive, which has a significant impact on the price of the aforementioned filling and / or emptying installation and therefore on the price of the container.

Un résultat que l'invention vise à obtenir est un conteneur du type précite qui, tout en étant au moins aussi fiable que celui précédemment décrit, soit d'un prix de revient moindre et d'une masse à vide compatible avec la limite maximale de masse totale en charge. A result which the invention aims to obtain is a container of the aforementioned type which, while being at least as reliable as that previously described, is of a lower cost price and an empty mass compatible with the maximum limit of total loaded mass.

A cet effet, la citerne de l'invention est caractérisée e ce que
- elle comprend au moins deux récipients sphériques sensiblement de même diamètre interieur et dont les épaisseurs des parois respectives sont voisines, lesquels récipients sont reliés entre eux deux à deux par un manchon globalement cylindrique de révolution de diamètre intérieur moindre que celui des récipients et qui, outre l'entretoisement et la liaison mécanique qu'il réalise entre les parois de ces récipients par ses extrémites permet la communication entre leur volume interne et,
- le diamètre intérieur de ce manchon cylindrique est tel que, compte tenu des conditions de résistance mécanique auxquelles il doit satisfaire, l'épaisseur de sa paroi soit sensiblement égale à celle des parois des récipients sphériques qu'il relie.To this end, the tank of the invention is characterized in that
it comprises at least two spherical receptacles substantially of the same internal diameter and the thicknesses of the respective walls of which are close, which receptacles are connected together in pairs by a generally cylindrical sleeve of revolution with an inner diameter less than that of the receptacles and which, in addition to the bracing and the mechanical connection which it makes between the walls of these containers by its extremities allows communication between their internal volume and,
- The internal diameter of this cylindrical sleeve is such that, taking into account the conditions of mechanical resistance which it must satisfy, the thickness of its wall is substantially equal to that of the walls of the spherical receptacles which it connects.

L'invention sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement et vue en coupe lonoitudinale, un exemple de réalisation de l'invention. The invention will be better understood with the aid of the description below given by way of nonlimiting example with reference to the appended drawing which schematically represents and seen in longitudinal section, an exemplary embodiment of the invention.

Avantagensement, mais non limitativement, la citerne est inscrite dans une structure 3 classiquement composée de poutres rigides agencées selon les arêtes d'un parallélépipède rectange. Advantageously, but not limited to, the tank is included in a structure 3 conventionally composed of rigid beams arranged along the edges of a rectangular parallelepiped.

Cette structure 3 permet principalement d'assurer la stabilité, l'orientation, l'ancrage sur un support et bien entendu la manutention de la citerne.  This structure 3 mainly ensures stability, orientation, anchoring on a support and of course the handling of the tank.

Tel que cela apparaît sur le dessin, la citerne de l'invention ,et en oeuvre des receptacl os à parois sph-riMues 4. As shown in the drawing, the tank of the invention, and implements receptacl bones with sph-riMues walls 4.

Les propriétés de resistance à 1 'éclateent des réceptacles sphériques sont bien connues. The properties of resistance to bursting of spherical receptacles are well known.

On sait en effet qu'à matériau identique et à diamètre égal, un récipient sphérique admet une même résistance à lteclatement pour une épaisseur de paroi qu'on admettra ici, pour approche, pratiquement deux fois moindre que celle d'un récipient sphérique. It is known in fact that with identical material and with equal diameter, a spherical container admits the same resistance to bursting for a wall thickness which will be admitted here, for approach, practically twice less than that of a spherical container.

L'invention exploite cette propriété. The invention exploits this property.

A cet effet,la citerne 1 de l'invention est caractérisée en ce que
- elle comprend au moins deux récipients sphériques 4 sensi bl eent de même diamètre intérieur D et dont les épaisseurs E des parois respectives 41 sont voisines, lesquels récipients sont reliés entre eux deux à deux par un manchon 5 globalement cylindrique de,révolution de diamètre intérieur d moindre que celui des récipients 4 et qui, outre 1 'entretoiseent et la liaison lilecanique qu'il réalise entre les parois de ces récipients par ses extrémités 51 permet la communication entre leur volume interne 42 et,
- le diamètre intérieur d de ce manchon cylindrique est tel que, compte tenu des conditions de résistance mécanique auxquelles il doit satisfaire, l'épaisseur de sa paroi 52 soit sensiblement égale à celle E des parois 41 des récipients sphériques 4 qu'il relie.To this end, tank 1 of the invention is characterized in that
- It comprises at least two spherical receptacles 4 sensi bl eent of the same internal diameter D and the thicknesses E of the respective walls 41 are close, which receptacles are connected together in pairs by a generally cylindrical sleeve 5, revolution of internal diameter d less than that of the containers 4 and which, in addition to the spacer and the lilecanic connection which it produces between the walls of these containers by its ends 51 allows communication between their internal volume 42 and,
- The internal diameter d of this cylindrical sleeve is such that, taking into account the conditions of mechanical resistance which it must satisfy, the thickness of its wall 52 is substantially equal to that E of the walls 41 of the spherical receptacles 4 which it connects.

Cette particularité est tres avantageuse pour la construction de la citerne. This feature is very advantageous for the construction of the tank.

En effet, les citernes de ce type qui sont réalisées en acier, sont constituées de plusieurs tronçons 12 de paroi ayant généralement une forme de révolution et qui sont assemblés par soudage bout à bout. Indeed, tanks of this type which are made of steel, consist of several wall sections 12 generally having a shape of revolution and which are assembled by butt welding.

Les épaisseurs des tronçons de parois ainsi assemblées bout à bout presentent toutes les caractéristiques requises pour leur assemblage optimal selon les techniques de soudage connues et notamment une épaisseur semblable.  The thicknesses of the wall sections thus assembled end to end have all the characteristics required for their optimal assembly according to known welding techniques and in particular a similar thickness.

De nrférence, les récipients sphériques 4 qui constituent la citerne sont chacun au droit de leur zone de raccordement à un manchon cylindrique 5 renforcé par un voile circulaire 6 d'épaisseur convenable, de diamètre sensiblement égal 'à celui du manchon 5 et dans lequel est réservée une ouverture 8 de communication avec le dit manchon. As a reference, the spherical receptacles 4 which constitute the tank are each in line with their connection zone to a cylindrical sleeve 5 reinforced by a circular veil 6 of suitable thickness, of diameter substantially equal to that of the sleeve 5 and in which is reserved an opening 8 for communication with said sleeve.

Selon l'invention, chaque voile 6 de renforcement est un élément monobloc d'épaisseur V superieure à celle des parois des récipients 4 et du manchon 5 mais qui présente deux collerettes 7, d'une part, situees et orientées dans le prolongement et, d'autre part, dont l'épaisseur W est sensiblement égale à celle des tronçons de citerne correspondante l'une de la paroi du manchon, l'autre de la paroi d'un récipient sphérique. According to the invention, each reinforcing web 6 is a one-piece element with a thickness V greater than that of the walls of the containers 4 and of the sleeve 5 but which has two flanges 7, on the one hand, located and oriented in the extension and, on the other hand, whose thickness W is substantially equal to that of the corresponding tank sections one of the wall of the sleeve, the other of the wall of a spherical container.

Conformément à l'invention, chaque voile de renforcement 6 comprend d'une part, centré sur l'axe longitudinal 53 de la citerne, une ouverture transversale 8 de diametre moindre que celui du manchon cylindrique 5 et, d'autre part, au moins un canal 9 qui le traverse de part en part tangentiellernent à la génératrice interne de la paroi 52 du manchon cylindrique 5 qui, compte tenu de l'orientation donnée à la citerne dans la structure support 4 qui l'englobe sera située au point le plus bas du manchon afin de permettre l'écoulement vers le récipient sphérique du fluide accumule dans le manchon cylindrique. According to the invention, each reinforcing veil 6 comprises on the one hand, centered on the longitudinal axis 53 of the tank, a transverse opening 8 of smaller diameter than that of the cylindrical sleeve 5 and, on the other hand, at least a channel 9 which crosses it right through tangentially to the internal generator of the wall 52 of the cylindrical sleeve 5 which, taking into account the orientation given to the tank in the support structure 4 which encloses it, will be located at the most bottom of the sleeve to allow the flow to the spherical container of the fluid accumulated in the cylindrical sleeve.

De préférence, la citerne comprend au moins une ouverture ou trou d'homme 13 avec pour l'obturer une trappe de visite 10 et l'ouverture 13 qui est realisee dans une embase 11 reliee à l'une des extrémités de la citerne et est centrée sur l'axe longitudinal 53 de cette dernière. Preferably, the tank comprises at least one opening or manhole 13 with for closing a inspection hatch 10 and the opening 13 which is produced in a base 11 connected to one of the ends of the tank and is centered on the longitudinal axis 53 of the latter.

Bien entendu, comme l'épaisseur de la trappe 10, celle de l'embase 4-1 est adaptée aux efforts engendres par la pression qui doit régner dans la citerne. Of course, like the thickness of the hatch 10, that of the base 4-1 is adapted to the forces generated by the pressure which must prevail in the tank.

A l'exemple du voile 6, l'embase 11 dans laquelle est réalisée l'ouverture 13 obturée par la trappe de visite 10 présente une collerette 111 d'épaisseur en rapport avec la paroi du récipient sphérique à laquelle elle doit être raccorde par soudure.  In the example of the veil 6, the base 11 in which the opening 13 is made closed by the inspection hatch 10 has a flange 111 of thickness in relation to the wall of the spherical container to which it must be connected by welding .

De préférence, chaque récipient sphérique 4 coil1prend sa partie haute, compte tenu de ltorientction qui lui est donnée par la structure 3, un doyen 18 tel un bossage de raccordement d'une soupape de securité.  Preferably, each spherical container 4 coil1 takes its upper part, taking into account the orientation which is given to it by the structure 3, a dean 18 such as a boss for connecting a safety valve.

Suivant l'invention, chaque moyen 14, 15 de raccordement d'organe de contrôle du passage du fluide en phase liquide et/ou gazeuse d'une part est un bossage solidaire de la paroi du manchon cylindrique qui relie deux à deux les récipients sphériques et, d'autre part est traversé par une conduite 16, 17 qui, selon la nature de la phase du fluide contrôlé débouche par l'une de ses extrémités dans tous les récipients sphériques et ce au point correspondant soit le plus haut pour la phase gazeuse et le plus bas pour la phase liquide compte tenu de l'orientation de la citerne dans la structure 3 qui l'englobe. According to the invention, each means 14, 15 for connecting the member for controlling the passage of the fluid in the liquid and / or gaseous phase on the one hand is a boss secured to the wall of the cylindrical sleeve which connects the spherical receptacles in pairs and, on the other hand, is crossed by a pipe 16, 17 which, depending on the nature of the phase of the controlled fluid, opens at one of its ends into all the spherical receptacles and this at the corresponding point, ie the highest for the phase gaseous and lowest for the liquid phase taking into account the orientation of the tank in structure 3 which encompasses it.

Outre l'économie réalisée sur les organes de contrôle du passage du fluide, d'ailleurs limités ici à un seul par phase liquide ou gazeuse, les gains-en volume utile et en poids, par rapport à un conteneur traditionnel à citerne pour haute pression sont considérables. In addition to the savings made on the organs for controlling the passage of the fluid, which are moreover limited here to only one per liquid or gas phase, the gains in useful volume and in weight, compared with a traditional tank container for high pressure. are considerable.

Correctement dimensionnées, les citernes ainsi concues peuvent être éprouvées pour des pressions très importantes et notamment de trois cents bars.  Properly sized, the tanks thus designed can be tested for very high pressures and in particular of three hundred bars.
