MRI machines use liquid helium to cool magnets. During an emergency shutdown, the magnets heat up, causing the helium to rapidly expand and vent through the quench pipe to the outside.

The Quench Vent system must handle the large gas volume (expansion ratio ~1:700) and extreme temperature shift from -452.2 °F to ambient within seconds. This exhaust system is vital for safe magnet operation.

The vent assembly must use non-magnetic stainless steel (e.g., type 304). Flexible sections or bellows accommodate thermal expansion. The system must be properly supported and guided to ensure alignment during temperature changes.
