L'ISO 21012:2018 définit la conception, le type et les tests de production ainsi que les exigences de marquage applicables aux tuyaux flexibles cryogéniques non isolés utilisés pour le passage des fluides cryogéniques dans la plage de conditions de fonctionnement suivante:
– température de service: entre – 270 °C et + 65 °C;
– diamètre nominal (DN): entre 10 et 100.
Les pièces d'extrémité de montage d'un accouplement quelconque relèvent du domaine d'application de l'ISO 21012:2018; néanmoins, les accouplements sont couverts par d'autres normes.
Le tuyau doit être conçu et soumis à essai de façon à respecter la pression nominale communément acceptée, c'est-à-dire PN 40 au minimum. Les tuyaux peuvent être ensuite sélectionnés avec une pression nominale (PN) supérieure ou égale à la pression maximale admissible (PS) de l'équipement à laquelle il doit être utilisé.
