ITIS | Product Testing
This burst disk has been tested at vacuum conditions using a two-stage rotary vane pump in combination with a roots pump for high pumping speed in the low and medium vacuum range.
A burst disk, also known as a pressure safety disc, rupture disc or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from over pressurization or potentially damaging vacuum conditions.
A rupture disk is a type of sacrificial part because it has a one-time-use membrane that fails at a predetermined differential pressure, either positive or vacuum.
The membrane is usually made out of metal but nearly any material (or different materials in layers) can be used to suit a particular application.
Burst disks are widely accepted throughout industry and specified in most global pressure equipment design codes (ASME, PED, etc.).
Rupture disks can be used to specifically protect installations against unacceptably high pressures or can be designed to act as one-time valves or triggering devices to initiate with high reliability and speed a sequence of actions required.
