Graphite gaskets are high-performance sealing elements made from pure, expanded, or reinforced graphite, designed for extreme temperatures, high pressures, and corrosive environments. They provide exceptional thermal stability, chemical resistance, and sealing, commonly reinforced with metal foil or tanged inserts for structural strength.
Key Characteristics & Benefits
Extreme Thermal Resistance: Suitable for high-temperature steam and heat transfer fluids, often exceeding 650 Degree C with reinforcement.
Excellent Chemical Compatibility: Chemically inert, making them resistant to most acids, alkalis, and solvents.
High Compressibility & Recovery: Conforms well to irregular, damaged, or uneven flange surfaces, maintaining a tight seal under pressure fluctuations.
Low Creep Relaxation: Maintains bolt load over time, reducing the need for re-tightening.
Non-Stick Surface: Graphite's low friction surface ensures easy removal from flange faces.
