  2. Rupture disc - Wikipedia

    en.wikipedia.org/wiki/Rupture_disc

    A rupture disc (burst) Pressure-effect acting at a rupture disc. A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.

    There is also "an upstream connected frangible disc safety relief device" [5] located on the valve assembly which is also known as the "tri-dimensional burst disk". This burst disk protects the user against a situation where the pressure in the bottle would increase with exposure to heat during a fire.

    A rupture disc, also known as a burst disc, bursting disc, or burst diaphragm, is a onetime use, non-resealing pressure relief device that, in most uses, protects a pressure vessel, equipment or system from over pressurization or potentially damaging vacuum conditions. A rupture disc is a sacrificial part because it has a one-time-use membrane ...

    The risk of this happening to a correctly rated disc, in good condition, on a correctly filled cylinder is very low. Burst disk over-pressure protection is specified in the CGA Standard S1.1. Standard for Pressure Relief Devices. [5] Bursting disc rupture pressure is generally rated at 85% to 100% of test pressure. [11]

  6. Pilot-operated relief valve - Wikipedia

    en.wikipedia.org/wiki/Pilot-operated_relief_valve

    At set pressure the valve snaps to full lift. This can be quite violent on large pipes with significant pressure. The pressure has to drop below the set pressure in order for the piston to reseat (see blowdown in relief valve article). Modulating The pilot is designed to open gradually, so that less of the system fluid is lost during each ...
