FSGGAG - Graphite Rupture Discs
The FSGGAG Graphite Rupture Discs are designed to be mounted on a stainless steel ring, enabling straightforward installation between flanges. This highly versatile rupture disc combines the mechanical strength of a steel holder with the exceptional properties of high-purity graphite. The graphite material is resistant to aggressive fluids and exhibits low sensitivity to temperature fluctuations in terms of bursting pressure. The disc offers a complete opening with fragmentation upon failure. It is recommended to use vacuum support for rupture pressures below 1.7 barg, while the discs are self-supporting at higher calibration settings.
