Replaceable FSGGRG graphite rupture discs are mounted on graphite
(available for pressures up to 10 bar g) or metal (up to 15 bar g)
holders. These discs are versatile and suitable for numerous
applications. Graphite rupture discs are very resistant to aggressive
fluids and low bursting pressure sensitivity to temperature variations.
Discs are made of very high purity graphite impregnated with phenolic
resins in order to make the product impermeable. Opening is total but
with fragmentation. Vacuum support is required for rupture pressures
below 1.7 barg. Discs are self-supporting at higher calibrations.
