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.
