Cryogenic vessels - Valves for cryogenic service (ISO/FDIS 21011:2023)

This document specifies the requirements for the design, manufacture and testing of valves for a rated
temperature of -40 °C and below (cryogenic service), i.e. for operation with cryogenic fluids in addition
to operation at temperatures from ambient to cryogenic.
It applies to all types of cryogenic valves, including vacuum jacketed cryogenic valves up to size DN
200. This document can be used as guidance for larger size valves. This document is not applicable to
pressure relief valves covered by ISO 21013-1.

Kryo-Behälter - Ventile für den Kryo-Betrieb (ISO/FDIS 21011:2023)

Dieses Dokument legt die Anforderungen an die Konstruktion, Herstellung und Prüfung von Absperr-armaturen bei einer Bemessungstemperatur von −40 °C und darunter (Kryo-Betrieb) fest, d. h. für den Betrieb mit tiefkalten Fluiden zusätzlich zum Betrieb bei Umgebungstemperaturen bis zu tiefkühlen Temperaturen.
Dieses Dokument gilt für alle Arten von tiefkalten Absperrarmaturen, einschließlich vakuum-isolierten tiefkalten Absperrarmaturen mit Nennweiten bis DN 200.
Dieses Dokument kann als Anleitung für Absperrarmaturen mit größeren Nennweiten angewendet werden.
Dieses Dokument gilt nicht für in ISO 21013 1 enthaltene Druck-Ablass-Einrichtungen.
