Flat seat rupture disc G-GM

graphite

DonadonSDD GM monoblock graphite rupture discs are versatile and suitable for numerous applications and can be directly inserted between flanges. 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. Tolerance - from +/- 10 % to +/- 20% Operating temperature - from -60 °C to 180 °C Operating margin - up to 75% Vacuum support - Available Fragmentation - Yes Use under valve - No Corrosion resistance - Very good - can be protected with a PTFE membrane Linings - No Container - Included, mounted between flanges Seals - Available in graphite Rupture sensor - Electrical PED Certification [CE STAMP] - Available
