GRX® Graphite Rupture Disc

REMBE® graphite rupture discs offer you the familiar REMBE® quality and reliability – even in extremely corrosive media, low pressures and high temperatures. 

Like all REMBE® rupture discs, the graphite rupture discs are also manufactured in Germany. The maximum working pressure is 90%* of the minimum burst pressure.

REMBE® graphite rupture discs are applicable for highest temperatures by using a unique chemical vapour deposition method (PyC coating).  The rupture discs are applicable from -180 °C up to +500 °C under oxidizing and reducing atmosphere, +1,500 °C under inert condition.

Depending on the application and nominal pipe size, the rupture discs are installed directly between flanges. If required, you will also receive a suitable signalling device which, in conjunction with your process control system, will inform you about the rupture disc's  response. Nominal pipe size available from DN 15 (1/2'') to DN 600 (24'') with burst pressures from 20 mbarg (~0.3 psig) to 63 barg (~900 psig).

Your advantages

  • Highest temperature resistance (+1500 °C under inert conditions) and leak-tightness due to an innovative coating.
  • FDA conformity**.
  • Highest corrosion resistance.
  • Extra long service life.
  • Temperature-independent material properties.
  • Product purity (carbon content ≥ 99,9 % for PyC coating).
  • Reusable vacuum support.
  • Simple installation.

*Depending on the respective application.

**Excluded processes with infant food and breast milk.
