The cable must be replaced after each response, like the bursting disc itself.

Safety Devices for Protection Against Excessive Pressure - Part 2: Bursting Disc Safety Devices

Unlike the prototype, the bursting disc also includes a blade with an inner edge that cuts the membrane upon displacement of the damper.

The bursting disk is placed in position and the retaining plug is screwed in tightly.

When a pressure borne by the rupture disk is greater than the pressure bearing capacity of the rupture disk, the rupture disk ruptures.

An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed.

A primary rupture disk is disposed over the primary exit orifice, and a secondary rupture disk is disposed over the secondary exit orifice.

The pressure vessel has a primary exit orifice (36) and a secondary exit orifice (40) in the mid-portion, and a primary rupture disk (38) and a secondary rupture disk (42) over the exit orifices.

A hinge assembly (100) for a rupture disk (10) is disclosed.

The blow-out device suitably comprises a frangible disc.

A burst disc (7) closes the closed end of the duct (4).

Other pressure relief devices (such as a burst disc) may be used outside the hydrogen storage system.

Further, the device comprises a burst disc assembly mounted to the housing within the through bore.

The burst disc assembly is configured to rupture at a predetermined differential pressure between the inner cavity and the environment outside the housing.

The non-exposed burst disc (118) is arranged to breach when the pyrotechnic charge is ignited and increases the gas pressure in the chamber (116) to a predetermined pressure.
