Bursting discs by GMI.

Bursting discs

The GMI bursting disc is a pressure relief safety device. It is designed to operate by bursting the disc, either by explosion or implosion. It is a single-use device because its operation is self-destructive. It is custom-made for your application.

The following criteria determine how our bursting discs are made:
-maximum operating pressure
-bursting pressure
-fluid conveyed
-operating temperature
-flow to be drained
-any pulsating flow
-presence or absence of vacuum in the installation
-whether or not the disc is non fragmenting
-disc material
-connection method.
