The invention relates to a multi-layer conduit or container for high-pressure fluids, formed by a series of layers (29, 30) of a solid material, with a hermetic volume or space (9, 10, 11) being provided between said layers. A certain quantity of fluid that is not aggressive to the layers is introduced into the spaces and the pressure inside said spaces is maintained at an intermediate pressure between that of the interior of the container and that of the external environment. The successive pressures in the inter-layer spaces decreasing in value towards the exterior. In addition, the temperature of the fluids in the spaces can be staggered. |
