Estimating the term…
The invention relates to a pressurised fluid container, in particular a pressurised gas cylinder, comprising a body (1) forming a sealed storage volume for the fluid. According to the invention, a first end of the body (1) comprises an opening (2), while a second end of the body (1) comprises a base (3) secured to the body (1). The body (1) is formed by a metal material, a metal alloy or aluminium. The container is characterised in that the base (3) comprises a metal material, a metal alloy or an aluminium alloy having an electronegativity on the Pauling scale that is greater than that of the material forming the body (1). The invention also relates to a method for the production of such a container.
-13. (canceled)
A pressurized fluid container, comprising a body forming a leak-tight storage volume for fluid, a first end of the body comprising an orifice, a second end of the body comprising a foot attached to the body, the body being composed of a metallic material, of a metal alloy or of aluminum, the foot comprising a metallic material, a metal alloy or an aluminum alloy having an electro-negativity according to the Pauling scale greater than the electro-negativity of the material making up the body, wherein the foot is attached to the body by adhesive bonding.
A process for fabricating a pressurized fluid container, from a body made of a metallic material, of a metal alloy or of aluminum, the body forming a leak-tight storage volume for fluid and being provided with an orifice located at a first end, the process comprising a step of attaching, to a second end of the body, a foot comprising a metallic material, a metal alloy or an aluminum alloy having an electro-negativity according to the Pauling scale greater than the electro-negativity of the material making up the body, and in that the foot is attached to the body by adhesive bonding.
