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.
Flat Composite rupture discs
Construction : Between 2 laser-cut metal foils lies a PTFE sealing diaphragm.
Non-fragmenting design Burst Pressure Range : Up 0,015 to 800bars Temperature range : Up -80 to 400°C Sizes : Up DN8 to DN900 Materials : Stainless steel, Nickel, Hastelloy...
Fully PTFE coated Performance Tolerance : Up +/-10% to +/-5%
On request
-to be set directly between flanges without holder
-Internal vacuum support
-Fully PTFE coated on process side
-Bi-directionnal disc
-Signal transmitter
Reverse rupture discs
Construction : Non-fragmenting design Burst Pressure Range : Up 1 to 600bars Temperature range : Up -80 to 400°C Sizes : Up DN15 to DN300 Materials : Stainless steel, Nickel, Hastelloy, Monel, Inconel... Performance Tolerance : Up +/-10% to +/-5%

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.
