Cryogenic vessels - Valves for cryogenic service

This standard specifies the requirements for the design, manufacture and testing of valves for cryogenic service, i.e. for operation with cryogenic fluids (as defined in prEN 1251-1:1995) below - 10 øC as well as at ambient conditions to allow for start-up and run-down. It specifies additional requirements for cryogenic service for the appropriate valve product standard.  It applies to sizes up to DN 150 and vacuum jacketed cryogenic valves. This standard is not applicable to safety valves and valves for liquefied natural gas (LNG).  It is intended that the valve be designed and tested to satisfy the generally accepted nominal pressure e.g. PN 40. Valves may then be selected with a PN equal to or greater than the maximum allowable pressure (PS) of the equipment to which it is to be used.

Kryo-Behälter - Absperrarmaturen für tiefkalten Betrieb

Diese Norm legt die Anforderungen an die Konstruktion, Herstellung und Prüfung von Absperrarmaturen für den tiefkalten Betrieb fest, d.h. für den Betrieb mit tiefkalten Fluiden unter -10°C (wie in prEN 1252-1:1995 definiert), wie auch den Betrieb bei Umgebungsbedingungen, um das Öffnen und Entleeren zu ermöglichen. Sie legt zusätzliche Anforderungen für den tiefkalten Betrieb für die jeweiligen Produktnormen von Absperrarmaturen fest.

Récipients cryogéniques - Robinets pour usage cryogénique

La présente norme spécifie les prescriptions relatives à la conception, à la fabrication et aux essais des robinets pour usage cryogénique c'est-à-dire destiné à fonctionner avec des fluides cryogéniques (tels que définis dans le prEN 1251-1:1995) à une température inférieure à -10 °C ainsi qu'à température ambiante pour permettre le démarrage et l'arrêt de l'installation qu'ils équipent. Elle spécifie les prescriptions supplémentaires pour usage cryogénique par rapport aux normes appropriées de robinets.
