GRAPHITE RUPTURE DISC GRX
REMBE
The first pure graphite rupture disc with FDA conformity
This rupture disc has been developed
for processes with corrosive media, low
pressure and temperatures of between
-180 °C and +500 °C under oxidizing and
reducing atmosphere, +1,500 °C under
inert conditions.
The GRX is applicable for highest
temperatures by using a unique
chemical vapour deposition method
(PyC coating). By this PyC coating, the
rupture disc holds significantly longer at
very high temperatures, while remaining
permanently leak-tight in comparison to
other coatings and impregnations.
For example: 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 a maximum working pressure of
80 % of the minimum burst pressure,
the GRX is usable for rupture pressures
from 20 mbar g. Nominal pipe size is
available from 1/2” to 24”. Optionally,
a vacuum support can be integrated,
which is installed without adhesive
components that would meld at very high
temperatures. The GRX is also available
with a burst indicator, upon request. The
signaling device will inform you about the
rupture disc response. The installation
occurs directly between the flanges.
Some facts about GRX
• Highest temperature resistance
(applicable from -180 °C up to +500 °C)
The GRX is applicable for
highest temperatures by
using a unique chemical
vapour deposition
method.
• Maximum leak-tightness due to an
innovative coating
• Extra long service life
• Highest corrosion resistance and
can therefore also be used with very
aggressive process media
• Also available in vacuum-resistant
design
• Special application coped by the new
coating technology: liquid sodium
process at 490°C
