A graphite rupture disc developed by German safety and control technology manufacturer REMBE has been designed as a completely leak-proof solution for processes that use corrosive media and ultra-high temperatures. Isostatic Graphite
Equipped with a pyro-carbon (PyC) coating the rupture disc can resist significantly higher temperatures while remaining leak tight, making it ideal for use in reactors, tanks, glass containers and other system parts in the chemical, petrochemical and pharmaceutical industries.
According to the company, the GRX possess temperature resistance between -180C and 500C (or 1,500C without an oxygen atmosphere).
“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 180C,” said the company in a statement.
Rembe's GRX® graphite rupture disc
Also designed for low and medium pressure usage, the GRX has an operating pressure ratio of up to 80% and burst tolerance of +/- 10%, making it 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.
Upon request, REMBE also offers the GRX with a burst indicator. These devices include a sensor that pairs with a rupture disc assemble to trigger an alert when a disc bursts.
“The installation occurs directly between the flanges or other clamp systems,” added the company.
