Abstract

The bottle for containing liquefied petroleum or other gas under pressure is fabricated from a length of spiral-welded cylinder to which suitable ends have been welded. The continuous spiral welding process is monitored continuously for quality by ultrasonic crack detection or other suitable method. The circumferential welds at top and bottom of the cylinder can also be checked in order to ensure the integrity of the whole bottle. A fitting (2) for filling and emptying the bottle can be welded to the top, while a suitable wear ring (4), which enables the bottle to stand upright, is welded to the base.

Description

L'invention est relative a une bouteille de gaz liquéfié et son procédé de fabrication. Elle trouvera notamment son application dans le stockage et le transport de gaz liquéfié. The invention relates to a liquefied gas bottle and its manufacturing process. It will find its application in particular in the storage and transport of liquefied gas.

Actuellement, les bouteilles de gaz se présentent généralement sous une forme extérieure cylindrique. La partie supérieure est constituée d'une calotte sensiblement hémisphérique, sur laquelle peut etre placé un robinet ou un moyen d'accrochage d'un dispositif permettant d'évacuer le contenu de la bouteille. Currently, gas cylinders are generally in a cylindrical outer shape. The upper part consists of a substantially hemispherical cap, on which can be placed a tap or a hooking means of a device for evacuating the contents of the bottle.

La partie inférieure est constituée d'une embase qui forme le fond de la bouteille sur lequel est fixée généralement par soudure une collerette annulaire qui sert de surface d'appui à la bouteille. The lower part consists of a base which forms the bottom of the bottle on which is generally fixed by welding an annular flange which serves as a support surface for the bottle.

La partie centrale est constituée d'une virole cylindrique sur laquelle sent rapportées la calotte et l'embats par soudure. La virole centrale est réalisée au moyen d'une tole eint--ee cylindriquement, les dedx extrémités de la tôle formant les génératrices du cylindre obtenu sons soudées ensemble pour former la virole.Puis, la soudure est con ttallee par un dispositif de type connu, par exemple visuel , et 41 tes cette verifícatíon la collerette et l'embase sont soudées sur la virole
La bouteille ainsi obtenue, présente deux soudures annulaires qui correspondent aux fixations de la calotte et de l'embase sur la virole et une soudure rectiligne située le long d'une génératrice de la bouteille qui ferme la v role. The central part consists of a cylindrical shell on which feels the cap and the gear by welding. The central ferrule is produced by means of a sheet which is cylindrical, the ends of the sheet forming the generatrices of the cylinder obtained are welded together to form the ferrule. Then, the welding is con ttallee by a device of known type , for example visual, and 41 tes this verifícatíon the collar and the base are welded on the ferrule
The bottle thus obtained has two annular welds which correspond to the fastenings of the cap and the base on the ferrule and a straight weld located along a generator of the bottle which closes the v role.

Les bouteilles réalisées selon le procédé actuel présentent un certain nombre d'inconvénients. En effet, la présence de la soudure rectiligne selon une des genératrices de la virole provoque une faiblesse locale, ce qui minimise la résistance de la bouteille aux efforts de compression tendant à l'ovaliser. Ainsi, lorsque les bouteilles sont couchées et empilées pour leur stockage, des bouteilles situées à la couche inférieure doivent supporter l'effort imposé par les bouteilles gerbées à la verticale de celles-ci qui tendent à les déformer en faisant subir un effort de flexion important au niveau des génératrices horizontales des viroles. Un déchirement de la soudure pourra résulter d'une charge excessive ou de choc encaissés par la virole. The bottles produced according to the current process have a certain number of drawbacks. Indeed, the presence of the rectilinear weld along one of the generatrices of the shell causes local weakness, which minimizes the resistance of the bottle to compression forces tending to ovalize it. Thus, when the bottles are lying down and stacked for their storage, bottles located at the bottom layer must withstand the force imposed by the bottles stacked vertically which tend to deform them by subjecting to a significant bending force. at the level of the horizontal generatrices of the ferrules. A tear in the weld may result from excessive load or shock received by the shell.

Un autre inconvénient provient du procédé même de fabrication. Another drawback comes from the very manufacturing process.

En effet, le procédé de cintrage déforme dans un premier temps la tôle, puis dans une opération ultérieure de reprise la soudure est réalisée, ce qui ne permet pas de fabrication en continu de la virole. Indeed, the bending process deforms the sheet initially, then in a subsequent operation of resumption the welding is carried out, which does not allow continuous manufacture of the shell.

Le but de la présente invention est de proposer une bouteille de gaz qui présente des moyens pour résister aux efforts de déformation radiaux, ce qui permettra notamment de gerber les bouteilles de gaz préalablement couchées. The object of the present invention is to provide a gas cylinder which has means for resisting the radial deformation forces, which will in particular allow stacking the previously coated gas cylinders.

Un autre but de la présente invention est de présenter un procédé de fabrication de la virole qui permette d'obtenir celle-ci en continu, le pliage de la tôle métallique étant réalisé conjointement avec la soudure et le contrôle de la soudure. Another object of the present invention is to present a process for manufacturing the shell which makes it possible to obtain the latter continuously, the bending of the metal sheet being carried out in conjunction with the welding and the welding control.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, qui nest donnée qu'à titre indicatif. Other objects and advantages of the present invention will become apparent from the description which follows, which is given for information only.

La bouteille de gaz liquéfié, constituée notamment d'une calotte, d'une virole et d'une embase soudées ensemble est caractérisée par le fait que la virole présente une soudure hélicoïdale. The bottle of liquefied gas, comprising in particular a cap, a ferrule and a base welded together is characterized in that the ferrule has a helical weld.

L'invention sera mieux comprise si l'on se réfère à la description ci-dessous, ainsi qu'au dessin en annexe qui en fait partie intégrante. The invention will be better understood if reference is made to the description below, as well as to the accompanying drawing which forms an integral part thereof.

- La figure 1 schématise, titre d'exemple, une bouteille de gaz selon l'invention.- Figure 1 shows schematically, by way of example, a gas cylinder according to the invention.

La figure l représente une bouteille de gaz de forme sensiblement cylindrique. La partie supérieure de la bouteille est constituée d'une calotte 10 de forme sensiblement hémisphérique sur laquelle est rapporté un robinet ou un dispositif d'accrochage 2 qui permet la mise en place d'une pièce de raccordement qui servira à évacuer le gaz contenu dans la bouteille. FIG. 1 represents a gas cylinder of substantially cylindrical shape. The upper part of the bottle consists of a cap 10 of substantially hemispherical shape to which is attached a tap or an attachment device 2 which allows the establishment of a connecting piece which will serve to evacuate the gas contained in the bottle.

La partie inférieure de la bouteille représentée à la figure 1 est constituée d'une embase 3 qui forme le fond de la bouteille et qui présente une collerette 4 annulaire qui sert de base d'appui à la bouteille. Cette collerette 4 pourra être rapportée sur le fond de la bouteille par soudure par exemple. The lower part of the bottle shown in Figure 1 consists of a base 3 which forms the bottom of the bottle and which has an annular flange 4 which serves as a support base for the bottle. This flange 4 can be attached to the bottom of the bottle by welding, for example.

Une virole 5 constituera le corps de la bouteille sur laquelle seront rapportées la calotte 1 et l'embase 3 par des soudures, respectivement 6 et 7. A ferrule 5 will constitute the body of the bottle on which the cap 1 and the base 3 will be attached by welds, respectively 6 and 7.

Selon l'invention, la virole 5 présentera un cordon de soudure 8 hélicoldal, enveloppant la virole en partant de la soudure 7 pour rejoindre la soudure 6. De par la disposition en hélice de cette soudure, la virole présentera une bonne résistance aux efforts de contraction radiaux. En effet, aucune génératrice de la virole n'est constituée en tièrement d'un cordon de soudure, mais sera formée en grande partie de la tôle de base et de quelques points de soudure. According to the invention, the shell 5 will have a helical weld bead 8, enveloping the shell starting from the weld 7 to join the weld 6. By the helical arrangement of this weld, the shell will have good resistance to the forces of radial contraction. Indeed, no generator of the shell is entirely made up of a weld bead, but will be formed largely from the base sheet and a few weld points.

La virole est constituée d'une tôle 9 enroulée en forme de spires jointivespour former un cylindre. Les bordures des spires jointives seront soudées ensemble par le cordon de soudure 8. The ferrule consists of a sheet 9 wound in the form of contiguous turns to form a cylinder. The edges of the contiguous turns will be welded together by the weld bead 8.

Le procédé de fabrication, selon l'invention de la virole 5 se fera en partant d'une tôle de préférence de grande longueur, qui sera cintrée et déformée latéralement pour constituer des spires plates jointives en forme de tubes. Selon un mode préférentiel de réalisation du procédé, ltopération de cintrage sera accompagnée de l'opération de soudure en continu des spires jointives pour constituer un tube cylindrique. Il sera avantageux de contrôler la soudure, en continu, aussitôt apres sa réalisation afin d'en vérifier sa qualité. Les moyens de vérification de la soudure en continu seront de tout type approprié, par exemple au moyen d'ultra-sons. The manufacturing process, according to the invention of the shell 5 will be done starting from a sheet preferably of great length, which will be curved and deformed laterally to form contiguous flat turns in the form of tubes. According to a preferred embodiment of the method, the bending operation will be accompanied by the operation of continuously welding the contiguous turns to form a cylindrical tube. It will be advantageous to continuously check the weld immediately after its completion in order to check its quality. The means for verifying the continuous welding will be of any suitable type, for example by means of ultrasound.

Le tube cylindrique, ainsi réalisé en grande longueur, sera découpé en tronçons qui formeront les viroles des bouteilles de gaz. Suivant le volume de la bouteille de gaz à réaliser, la longueur de la virole pourra être plus ou moins grande. The cylindrical tube, thus produced in great length, will be cut into sections which will form the rings of the gas cylinders. Depending on the volume of the gas cylinder to be produced, the length of the shell may be more or less.

La virole, obtenue selon le procédé, sera ensuite équipée de la calotte 1 et de 1'embase 3 qui lui seront adjointes par soudure. Un contrôle de ces dernières soudures sera de préférence réalisé afin de s'assurer de la parfaite qualité de la bouteille. The ferrule, obtained according to the method, will then be fitted with the cap 1 and the base 3 which will be added thereto by welding. A check of these last welds will preferably be carried out to ensure the perfect quality of the bottle.

La fabrication en continu de la virole permet notamment d'en abaisser son coût de revient, ce qui est particulièrement avantageux. The continuous manufacture of the ferrule makes it possible in particular to lower its cost price, which is particularly advantageous.

D'autres formes géométriques du corps de la bouteille auraient pu être adoptées sans pour autant sortir du cadre de la présente invention. Other geometric shapes of the body of the bottle could have been adopted without departing from the scope of the present invention.
