Graphite gaskets are high-performance sealing materials made from flexible or reinforced graphite, known for their exceptional thermal resistance, chemical stability, and sealing effectiveness. Designed to withstand extreme environments, graphite gaskets are commonly used in industries where high temperature, pressure, and aggressive media are present.
The primary function of a graphite gasket is to provide a tight, reliable seal between two mating surfaces, preventing the leakage of gases or liquids even under harsh conditions. Thanks to graphite’s natural properties, these gaskets offer excellent resistance to heat (up to 450°C in oxidizing environments and over 3000°C in non-oxidizing conditions), pressure, and chemicals such as acids, alkalis, and solvents. They also have excellent compressibility and recovery, ensuring a long-lasting seal even with thermal cycling or mechanical load variations.
Graphite gaskets are widely used in power generation, petrochemical, chemical processing, metallurgy, and marine industries. In power plants and refineries, they are installed in flanges, valves, pumps, and heat exchangers to prevent leaks under extreme conditions. In the chemical industry, graphite gaskets are favored for their chemical resistance in piping systems and reactors. They are also used in automotive and aerospace applications for exhaust systems, engine components, and turbocharger sealing, where thermal stability is essential.
In summary, graphite gaskets are indispensable in sealing solutions for high-temperature, high-pressure, and corrosive environments. Their durability, chemical inertness, and ability to maintain integrity under fluctuating conditions make them a preferred choice in critical industrial applications.
