Abstract
A metal tank (1) for storing fluid under high pressure, comprising, along its axis (2), a plurality of adjacent compartments (10, 71, 91) separated by partitions (3), each compartment having a cylindrical wall (72), a transition zone (73) connecting each partition to the cylindrical wall, the compartments communicating with one another via at least one orifice (6) made in each partition, in which, for a given compartment, the cylindrical wall is connected via an annular weld (75) to the transition zone of the adjacent compartment.

A metal tank for storing fluid under high pressure, comprising, along its axis, a plurality of adjacent compartments separated by partitions, each compartment having a cylindrical wall, a transition zone connecting each partition to the cylindrical wall, the compartments communicating with one another via at least one orifice made in each partition, in which, for a given compartment, the cylindrical wall is connected via an annular weld to the transition zone of the adjacent compartment.
A method of manufacturing a metal tank for storing fluid under high pressure, the method comprising the following steps in turn:
- forming basic elements comprising a cylindrical wall of round cross section, a partition comprising an orifice and fitted perpendicular to the axis of the cylindrical wall, a transition zone connecting a first end of the cylindrical wall to the partition, a second end of the cylindrical wall constituting a free edge;
- juxtaposing a plurality of identical basic elements in such a way as to cause the respective axes of the cylindrical walls to coincide;
- and
- joining the said plurality of basic elements together by welding the free edge of the end of the cylindrical wall of each basic element to the transition zone of the adjacent element.
