The graphite rupture disc GRX has been developed for processes with corrosive media, low pressure and temperatures of between -180 and 1500 °C. The GRX is available with a synthetic resin coating (process temperatures up to 200 °C), as well as a PyC coating, developed specifically for the GRX (temperatures above 200 °C). With the PyC coating, the rupture disc holds significantly longer at very high temperatures, while remaining permanently leak-tight. With an operating pressure ratio of up to 90 % and burst tolerances of ±5 %, the GRX is usable for rupture pressures from 0.02 bar. Optionally,
a vacuum 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. So far, the GRX has already been installed in various reactors, tanks, glass containers and other system parts in the chemical and petrochemical industry.
