Rupture Discs

Hansen rupture disc assemblies (RDAs) are used to
indicate which pressure-relief valve has discharged.
A pressure-relief valve will re-seat after discharging.
However, a rupture disc remains open after bursting.
(A rupture disc is not a stand alone safety device.) An
installed pressure gauge or switch (required by code)
provides a visual or electronic indication that the rupture
disc has burst. Also, rupture disc assemblies provide
a hermetic seal to help eliminate any possibility of
minute losses of refrigerant via pressure-relief valve
seat materials. Hansen rupture disc assemblies are designed with a
welded construction. There are no gaskets to leak.

These rupture disc assemblies are typically used between
a vessel (or 3-way valve) and a pressure-relief valve.
They must be used for atmospheric, not differential,
pressure-relief. Rupture disc assemblies are required
when using Hansen pressure-relief valves for halocarbon
applications because the high cost of such refrigerants
demands extreme tightness.
