Pressure Relief Valves for Cryogenic Applications
Houston (August 03, 2020)
Pressure relief valves (PRVs) are a necessary requirement for overpressure protection within the LNG industry. However, not all PRVs are created equally when it comes to performance within cryogenic applications, and design temperatures as low as -320˚F (-196˚C). These applications require PRVs with enhanced sealing features to address the cryogenic conditions and perform their safety function.
PRVs are the last line of defense to protect equipment and personnel from an overpressure event. Construction materials, trim designs, and anti-galling measures are all critical components of a PRV design, as they help to address their challenging applications.
In this article published in the August 2020 edition of LNG Magazine, Author Matt Byers, Senior Product Manager, Baker Hughes, USA, outlines the engineering best practices used today to optimize the design of pressure relief valves operating under cryogenic conditions.
