Composite bursting discs

The task of these bursting discs, which are often installed ahead of a safety valve, is to proveide pressure relief at low to medium bursting pressures.
Because all-metal rupture foils have rather high burst pressures and also give off fragments of foil, we use our composite design:
laser-cut metal foils (stainless steel, nickel or nickel-base alloys) open segmentally or in a hinged type of way at burst pressures defined by the lines along which they are cut; between the slit metal foils there lies a PTFE sealing diaphragm. There may be additionally provided vacuum supports, metal sealing foils or coatings for sterile use.
However, the temperature range in which composite bursting discs can be used is limited to a maximum of 200°C by the internal sealing foil made of PTFE.
A special feature of these composite bursting discs is the possibility of mounting them directly between flanges.
