Graphite Laminate Gasket is a sealing material made of flexible graphite sheets reinforced with a metallic layer, such as stainless steel, nickel, or carbon steel. Common reinforcement styles include flat, tanged, and perforated sheets, which significantly enhance the gasket’s mechanical strength and pressure resistance. It is widely used in oil, chemical, power, and metallurgical industries for pipeline flanges and pressure vessels.
Performance
- Excellent temperature resistance: applicable from -200℃ to 450℃
- Outstanding chemical resistance against most acids, alkalis, salts, and organic solvents
- Superior compressibility and recovery, maintaining reliable sealing under high temperature, high pressure, and thermal cycling
- Very low leakage rate, suitable for critical sealing applications
Advantages
- Combines the heat and chemical resistance of graphite with the strength and stability of metal reinforcement
- Long service life with low maintenance cost
- Easy installation and compatibility with standard flange sizes
- Customizable in shape and structure to suit various demanding applications
