FSGGAG graphite rupture discs are mounted on a stainless steel ring that
can be directly inserted between flanges. This disc is very versatile
because combines the mechanical robustness of a steel holder and the
characteristics of graphite discs (resistant to aggressive fluids and
low bursting pressure sensitivity to temperature variations). Disc
material is high purity graphite. Opening is total but with
fragmentation. Vacuum support is required for rupture pressures below
1.7 barg. Discs are self-supporting at higher calibrations.
