Embodiment Construction

[0028] figure 1 A pressurized fluid container, in particular a pressurized gas cylinder, is schematically shown. The container includes a body 1, for example, the body 1 is cylindrical, forming a fluid-tight storage space. The shoulder-shaped first end of the body 1 comprises a bore 2 for accommodating eg a valve. The second end of the body 1 is protruding and includes legs connected to the body 1 . Typically, the body 1 is made or consists of a metal material, a metal alloy or aluminum.

[0029] According to a preferred distinguishing feature, this foot 3 is made or consists of a metallic material, a metal alloy or an aluminum alloy, which is more electronegative according to the Pauling scale than the material constituting the body 1 .

[0030] In this way, the legs 3 are corroded preferentially as anodes with respect to the body 1, which protects the body 1 of the container from possible risks of corrosion. Specifically, if there is a dangerous liquid, such as water, ac...

Abstract

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.

Description

technical field [0001] The invention relates to a pressurized fluid container and its manufacturing process. [0002] The present invention more particularly relates to a pressurized fluid container, especially a pressurized gas cylinder, which includes a body forming a fluid-tight storage space, a first end of the body includes a hole, and a second end of the body includes a foot provided on the body , the body is made of metal material, metal alloy or aluminum. Background technique [0003] Pressurized gas containers or cylinders are included in standards such as the international standard ISO 9809. These high-pressure vessels (usually for pressures greater than 60 bar) are called "seamless" because their construction is usually based on a forming process, usually using steel sheets or billets or steel tubes that are hot-pressed to obtain a "monolithic" vessel. Containers obtained using welding processes do not allow this type of structure over their entire surface. [...
