Graphite rupture discs provide long temperature resistance

The GRX graphite rupture disc (photo) has been developed for processes with corrosive media, low pressure and temperatures between –180 and 1,500°C. The GRX is available with a synthetic resin coating (for process temperatures up to 200°C), as well as the PyC coating, developed specifically for the GRX (for temperatures above 200°C). With the PyC coating, the rupture disc holds significantly longer at very high temperatures, while remaining permanently leak-tight, says the company. Rupture discs with a coating made of synthetic resin would no longer be able to offer this leak tightness at temperatures far above 200°C. With an operating pressure ratio of up to 90% and burst tolerances of±5%, the GRX is usable for rupture pressures from 0.02 bars. Optionally, a vacuum support can be integrated, which is installed without adhesive (which may melt at very high temperatures). The GRX is also available with a burst indicator, upon request. The installation occurs directly between the flanges. The GRX is suitable for installation in reactors, tanks, glass containers and more. — Rembe GmbH, Brilon, Germany
