A wall for making tanks includes two superimposed plates connected to each other at respective spaced apart connected points distributed on a surface of the plates, at least one of the two plates, between respective connecting zones, bulging outward, so that separation between the two plates increases in every radial direction with distance from each connected point to a maximum separation midway between neighboring connected points. The wall has a quilted appearance.

1. A wall structure for making tanks, the wall structure comprising two superimposed plates connected to each other at respective spaced apart connecting points distributed in an array on a surface of the plates, at least one of the two plates, between respective connecting points, bulging outward, separation between the two plates in every radial direction from each connecting point continuously increasing with distance from each connecting point toward a neighboring connecting point, to a maximum separation midway between pairs of neighboring connecting points, the wall having a quilted appearance. 2. The wall structure as set forth of claim 1, wherein the plates are connected at the connecting points by one of welds, an adhesive, and a brazing material. 3. The wall structure as set forth in claim 1, wherein the two plates have respective edges that are continuously joined as fixation edges for mounting the wall on a support structure. 4. The wall structure as set forth in claim 1, wherein the two plates are selected from the group consisting of metallic and non-metallic materials. 5. The wall structure as set forth in claim 4, wherein the two plates are selected from the group consisting of homogeneous and heterogeneous materials. 6. A tank comprising a first volume enclosed within a second volume with a third volume between the first and second volumes, wherein a wall structure of the tank defines the first, second, and third volumes and comprises two superimposed plates connected to each other at respective spaced apart connecting points distributed in an array on a surface of the plates, at least one of the two plates, between respective connecting points, bulging outward, separation between the two plates in every radial direction from each connecting point continuously increasing with distance from each connecting point toward a neighboring connecting point, to a maximum separation midway between pairs of neighboring connecting points, the wall structure having a quilted appearance, the first volume being defined by an inside one of the two plates and for containing a fluid, the second volume being defined by an outside one of two plates, and the third volume being disposed between the two plates and collecting leakage of fluid from the first volume, the third volume communicating outside the tank for evacuation of leaking fluid reaching the third volume. 7. The wall structure as set forth in claim 1 wherein both of the two plates bulge outwardly between respective pairs of connecting points. 8. A tank having a wall comprising two superimposed flat plates connected to each other at respective spaced apart connecting points distributed in an array on a surface of the two plates and inflatable by injection between the two plates of a pressurized fluid to produce a quilted appearance, at least one of the two plates bulging outward after injection of the pressurized fluid, separation between the two plates, in every radial direction from each connecting point increasing continuously with distance from each connecting point toward a neighboring connecting point, to a maximum separation midway between pairs of neighboring connecting points, the wall having a quilted appearance and a variable resistance to mechanical stresses determined by locations of the connecting points in the array and pressure of the pressurized fluid. 9. The tank as set forth in claim 6 wherein both of the two plates bulge outwardly between respective pairs of connecting points. 10. The wall structure as set forth in claim 1 wherein only one of the two plates bulges outwardly between respective pairs of connecting points. 11. The tank as set forth in claim 6 wherein only one of the two plates bulges outwardly between respective pairs of connecting points.
