Abstract
A tank for a cryogenic fluid, of the type comprising an inner vessel (2) intended to receive the cryogenic fluid and delimiting, with an outer vessel (8), a space (9) for the insertion of multilayer thermal insulation (7). The tank comprises multilayer thermal insulation (7) supporting the inner vessel (2) and an outer vessel (8) without a rigid connection to the inner vessel (2).
Claims3
A tank for carrying low temperature cryogenic fluids, comprising:
- an inner vessel defining an inner volume for receiving a cryogenic fluid;
- fluid conduit means opening into the inner volume for admitting in fluid and withdrawing fluid from the inner volume;
- a multilayer thermal insulation disposed around the inner vessel and consisting of wrapped superpositions of composite bands, each consisting of an insulating material and of a thermal reflector superposed thereto;
- and
- an outer vessel mounted around the multilayer thermal insulation, the fluid conduit means extending in a flexible manner through the multilayer insulation and the outer vessel, whereby said fluid conduit means are free from rigid connection with both the inner and outer vessels and no rigid link exists between the inner and outer vessels.
A tank for carrying low temperature cryogenic fluids, comprising:
- an inner vessel defining an inner volume for receiving a cryogenic fluid;
- fluid conduit means opening into the inner volume for admitting in fluid and withdrawing fluid from the inner volume;
- a multilayer thermal insulation disposed around the inner vessel and consisting of wrapped superpositions of composite bands, each consisting of an insulating material and of a thermal reflector superposed thereto;
- an outer vessel mounted around the multilayer thermal insulation so as to pre-stress said multilayer thermal insulation between the inner and outer vessels, with no rigid link existing between said inner and outer vessels;
- and
- wherein at least part of said fluid conduit means extending within said inner vessel is flexible.

- an outer vessel mounted around the multilayer thermal insulation so as to pre-stress said multilayer thermal insulation between the inner and outer vessels, with no rigid link existing between said inner and outer vessels;
- and
- wherein said fluid conduit means are flexible and partly accommodated in a recessed part of the inner vessel substantially devoid of the multilayer thermal insulation.
