This rupture disc has been developed for processes with corrosive media, low and medium pressure and temperatures of between -180 °C and 1,500 °C.
The GRX is available with a Pyro-Carbon (PyC) coating, developed specifically for the GRX. By the PyC coating, the rupture disc resists significantly higher temperatures, while remaining permanently leak-tight. Other Graphite rupture discs with a coating made of PTFE or impregnation of synthetic resin are not able to offer this leak-tightness at temperatures above 180 °C.
With an operating pressure ratio of up to 80 % and burst tolerances of +/- 10 %, the GRX is usable for rupture pressures from 0.05 bar. Optionally, a vacuum or back pressure support can be integrated, which is installed without adhesive (which melts at very high temperatures). The GRX is also available with a burst indicator, upon request. The installation occurs directly between the flanges or other clamp systems. So far, the GRX has already been installed in various reactors, tanks, glass containers and other system parts in the chemical, petrochemical and pharmaceutical industry.
Special features of the GRX
- Temperature resistance up to 500 °C (or 1,500 °C without O2 atmosphere)
- More resistant to very aggressive media
- FDA-compliant
