Power Generator - Specific Advantages

1. Thermal Management
   • Operates reliably in temperature ranges from cryogenic (-200°C) to superheated steam conditions (+650°C), ensuring consistent sealing in boiler systems and turbine housings.
   • Low thermal conductivity prevents heat loss in high - efficiency power plants.
2. Vibration & Pressure Resistance
   • Withstands cyclic pressures up to 100 bar and mechanical vibrations in rotating equipment like alternators and gas turbines.
   • Compression set resistance maintains gasket integrity under prolonged stress.
3. Electrical Conductivity
   • Graphite’s inherent conductivity dissipates static charges in generator components, reducing risk of electrical arcing.

Applications in Power Generation

1. Turbine Sealing
   • Used in steam, gas, and hydroturbines to prevent leaks in high - velocity fluid paths.
   • Composite versions with stainless steel reinforcement provide structural support in high - pressure zones.
2. Heat Exchanger Gaskets
   • Seals between tube bundles and headers in condensers and boilers, resisting thermal cycling and chemical attack from cooling water.
3. Generator Housing Seals
   • Maintains hermetic seals in hydrogen - cooled generators, preventing gas leakage and ensuring electromagnetic compatibility.
