Cryogenic vessels - Couplings for cryogenic service

This European Standard specifies the minimum requirements for the design, manufacture and testing of couplings for cryogenic service to be used for temporary connecting of flexible hoses to cryogenic vessels at the following operating conditions :
- design temperature range from - 270 ° C to + 65 ° C ;
- maximum nominal pressure : 80 bar ;
- nominal size (DN) from 10 to 100.
Permanent connections such as flanges and unions are not covered by this standard.
It is intended that the couplings should be designed, tested and marked for service at one of the generally accepted pressure e.g. PN 40. Couplings can then be selected with a PN equal to or greater than the maximum allowable pressure (PS) of the equipment for which they are to be used.

Kryo-Behälter - Kupplungen für den tiefkalten Betrieb

Diese Norm legt Mindestanforderungen für Auslegung, Herstellung und Prüfung von Kupplungen für den tiefkalten Betrieb fest, die zeitlich begrenzt zur Verbindung von flexiblen Rohren (Schläuchen) unter folgenden Betriebs-bedingungen verwendet werden:
- Auslegungstemperatur: von - 270°C bis + 65 C,
- maximaler Nenndruck :80 bar,
- Nennweite (DN): 10 bis 100.
Ständige Verbindungen wie Flansche und Rohrverbindungsstutzen fallen nicht unter den Anwendungsbereich dieser Norm.
Es ist anzustreben, dass Kupplungen für eine genormte Druckstufe, z. B. PN 40, bemessen, geprüft und gekennzeichnet werden. Die Kupplungen können dann so ausgewählt werden, dass ihr Nenndruck PN gleich oder größer ist als der maximal zulässige Druck (PS) der Einrichtung , in den sie angewendet werden.

Récipients cryogéniques - Raccords pour service cryogénique

La présente Norme européenne spécifie les exigences minimales relatives a la conception, a la fabrication et aux essais des raccords pour service cryogénique utilisés temporairement pour raccorder les flexibles aux récipients cryogéniques dans les conditions suivantes de fonctionnement :
- plage de températures de calcul comprise entre - 270 °C et + 65 °C ;
- pression nominale maximale : 80 bar ;
- diametre nominal (DN) de 10 a 100.
Les raccords a usage permanent tels que les brides et autres raccords unions ne sont pas couverts par la présente Norme européenne.
Il est recommandé de concevoir, essayer et marquer les raccords pour le service a une pression généralement admise, par exemple PN 40. Ils peuvent alors etre associés a des récipients dont la pression maximale admissible (PS) est inférieure ou égale a leur pression nominale.
