Cryogenic vessels - Pressure-relief accessories for cryogenic service - Part 1: Reclosable pressure-relief valves
This document specifies the requirements for the design, manufacture and testing of pressure relief valves for cryogenic service, i.e. for operation with cryogenic fluids below 10 °C in addition to operation at ambient temperatures from ambient to cryogenic.
This document is applicable to valves not exceeding a size of DNÂ 150 designed to relieve
single-phase vapours or gases. A valve can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.
NOTEÂ Â Â Â Â Â This document does not provide methods for determining the capacity of relief valve(s) for a particular cryogenic vessel. Such methods are provided in ISOÂ 21013-3.
