PRESSURE RELIEF VALVE (IMAGE)
Caption
In this image, liquid nitrogen is expelled through a pressure relief valve as part of an SwRI-conducted test to determine their viability for liquid natural gas tanks in the event of a train derailment. The Institute contributed to a Federal Rail Administration report that shows that a study conducted by SwRI demonstrated that the pressure relief valves work as designed to prevent overpressurization and explosion if a derailment occurs.
