Exceptional Properties of Graphite

Graphite gaskets derive their exceptional sealing properties from the unique characteristics of graphite, a form of carbon known for its high thermal conductivity, chemical inertness, and low friction. Graphite possesses a layered structure with strong covalent bonds within the layers and weak van der Waals forces between them, imparting flexibility and resilience to the material. This allows graphite gaskets to conform to irregularities in sealing surfaces, ensuring a tight and reliable seal even under extreme conditions.

Applications Across Industries:

Graphite gaskets find application in a wide range of industries where reliable sealing is essential for operational integrity. From petrochemical plants and refineries to power generation facilities, aerospace applications, and high-performance automotive engines, graphite gaskets excel in sealing flange connections, valve bonnets, heat exchangers, and other critical components. Their ability to withstand high temperatures, pressures, and aggressive chemicals makes them indispensable in environments where conventional gaskets may fail.

Versatile Forms and Configurations:

Graphite gaskets are available in various forms and configurations to suit different sealing requirements and application conditions. Sheet graphite gaskets, reinforced with metal or non-metallic inserts, offer flexibility and ease of installation, making them suitable for a wide range of flange connections. Spiral wound graphite gaskets combine the resilience of graphite with the strength of metallic windings, providing superior sealing performance in high-pressure and high-temperature applications. Additionally, graphite gaskets can be custom-cut to specific dimensions or shapes to meet unique sealing challenges.

Benefits of Graphite Gaskets:

  • High Temperature Resistance: Graphite gaskets can withstand temperatures ranging from cryogenic to extreme heat, making them ideal for sealing applications involving steam, hydrocarbons, acids, and other high-temperature fluids.
  • Chemical Compatibility: Graphite exhibits excellent resistance to a wide range of chemicals, including acids, alkalis, solvents, and gases, ensuring reliable sealing performance in corrosive environments.
  • Low Leakage Rates: The conformability of graphite allows it to create a tight and uniform seal, minimizing the risk of leakage and ensuring efficient containment of fluids and gases even under fluctuating pressures.
  • Longevity and Durability: Graphite gaskets are known for their durability and long service life, providing reliable sealing performance over extended periods without degradation or loss of resilience.
