(Main)LPG Equipment and accessories - Pressure relief valves for LPG pressure vessels
General Information
- Abstract
This European Standard specifies the requirements for the design and testing of spring loaded pressure relief valves and thermal expansion valves for use in:
- static LPG pressure vessels,
NOTE The pressure vessels can be situated above ground, underground or mounded.
- LPG pressure vessels on road tankers, rail tankers, tank-containers or demountable tanks.
This document does not address production testing.
Normative Annex B prescribes testing with conditioning at - 40 °C for valves for use under extreme low temperature conditions.
The requirements for pressure relief valve accessories such as isolating devices, changeover manifolds and vent pipes are specified in EN 14071.
EN 14570 identifies the requirements for the pressure relief valve capacities for static pressure vessels.
