MARSTON – Graphite Rupture Discs – Bursting Discs

GR Graphite Discs

A flat graphite disc, impregnated with a high quality resin, giving good corrosion resistance and low bursting pressures. The unique GR arrangement is designed to protect the disc from the effects of flange bolt loading. This disc fragments on rupture. This disc is thin in construction and designed to operate with its interaction with its holder. Vacuum resistance is available with a special metal dial in the holder. The disc should be operated to 80% of its minimum burst pressure in static conditions and up 50% in cyclic conditions to maximise its service life.

Monobloc Graphite Discs

A flat graphite disc, impregnated with a high quality resin, giving good corrosion resistance and low bursting pressures. This disc does not require a dedicated holder, and fragments on rupture. Vacuum resistance is possible with an additional dial (bar type) or dial type support on its underside. This disc shall be operated to 80 of its minimum burst pressure in static conditions or 50% in cyclic conditions to maximise its service life.

GRB Graphite Reverse Buckling Disc Assemblies

A unique disc manufactured from pure graphite powder. It is suitable for high temperatures and extremely low bursting pressures. This disc will fragment on rupture.
