PDISK 1900

Replacement 1900 psig (13,100 kPag) burst disk kit - For ALTA-ROBBINS HARDWARE ONLY.

A rupture disc, also know as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief device that protects a pressure vessel, equipment or system from overpressurization conditions

 A rupture disc is a type of sacrificial part because it has a one-time-use membrane that fails at a predetermined differential pressure, the PDisk-1900 is rated for 1900psig. The membrane is made out of metal. Rupture discs provide instant response (within milliseconds) to an increase in the system pressure, but once the disc has ruptured it will not reseal. Major advantages of the application of rupture discs compared to using pressure relief valves include leak-tightness and cost.

Rupture discs are commonly used in petrochemical, aerospace, aviation, defense, medical, railroad, nuclear, chemical, pharmaceutical, food processing and oil field applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the rupture disc will burst. Rupture discs are very often used in combination with safety relief valves, isolating the valves from the process, thereby saving on valve maintenance and creating a leak-tight pressure relief solution.

Rupture discs are widely accepted throughout industry and specified in most global pressure equipment design codes (ASME, PED, etc.). Rupture discs 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.
