  • Multilayer tubular structure intended for transporting an air-conditioning fluid
    Patent number: 11338541
    Abstract: A multilayer tubular structure intended for transporting a heat-transfer fluid, the multilayer tubular structure including: a first layer including at least one long-chain polyamide having between 10 and 15 carbon atoms per nitrogen atom and including at least 50% aliphatic units relative to the sum of the units present in the long-chain polyamide; a second layer including at least one polyamide having between 4 and 9 carbon atoms per nitrogen atom, the polyamide including at least 50% aliphatic units relative to the sum of the units present in the polyamide; an optional layer, the first layer containing no continuous fibres, the second layer being in contact with the transported fluid when an optional layer is not present, and the layer or layers representing at least 50% of the total thickness of the tube.
    Type: Grant
