ISO 21013-2:2007 specifies the requirements for the design, manufacture and testing of non‑reclosable pressure‑relief devices for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. ISO 21013-2:2007 is restricted to bursting‑disc and buckling‑pin devices not exceeding a size of DN 200 designed to relieve single‑phase vapours or gases. A bursting‑disc or buckling‑pin assembly may be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases. ISO 21013-2:2007 does not provide methods for determining the capacity of bursting disc or buckling pin devices for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.
Abstract
Overview
ISO 21013-2:2007 - Cryogenic vessels: Pressure‑relief accessories for cryogenic service - Part 2 covers the design, manufacture and testing of non‑reclosable pressure‑relief devices for cryogenic service. It is focused on bursting‑disc and buckling‑pin devices (size DN 200 and below) intended to relieve single‑phase vapours or gases at temperatures from ambient down to cryogenic. ISO 21013-2 sets material, testing, marking and cleanliness requirements for safe operation with cryogenic fluids. (Sizing and capacity methods are outside its scope - see ISO 21013‑3.)
Key topics and technical requirements
- Scope limits: applies to non‑reclosable bursting‑disc and buckling‑pin devices ≤ DN 200, single‑phase vapour/gas service.
- Design temperatures: rated minimum = equilibrium temperature at atmospheric pressure of the coldest fluid; rated maximum normally +65 °C unless otherwise specified. Coincident temperatures default to 20 °C (ambient) and 427 °C (fire) unless specified.
- Materials & compatibility: metallic and non‑metallic materials must meet toughness and low‑temperature requirements (see ISO 21028‑1/‑2). Materials must be compatible with process fluids and oxygen‑compatible when relevant (ISO 21010). Hydrogen and acetylene compatibility provisions referenced (ISO 11114; copper content
