Structure and Principle

Serrated gaskets are composite gaskets made of metal and non-metal materials. The metal part, typically high-quality steel or stainless steel, provides strength and toughness to withstand high pressure and temperature. The non-metal part, often flexible graphite or PTFE, offers excellent sealing, corrosion resistance, and adaptability. Supported by metal serrations, these materials form a robust barrier that effectively prevents fluid leakage.

Advantages of Serrated Structure:

  • Tight contact with equipment surfaces

  • Even pressure distribution

  • Stable sealing under vibrations and pressure fluctuations

  • Effective in harsh conditions, including high temperature, high pressure, and corrosive environments

Role of Composite Materials:Flexible graphite maintains performance at high temperatures, while PTFE provides superior chemical stability. The combination ensures reliable sealing in complex industrial conditions.

Performance Features

  • Superior Sealing Performance: Prevents leakage of gases and liquids, maintaining stable sealing even under extreme conditions.

  • High Temperature and Pressure Resistance: Operates reliably at temperatures up to 650°C (graphite) and over wide ranges for PTFE.

  • Strong Corrosion Resistance: Resists chemical erosion, suitable for petrochemical and chemical industries.

  • Easy Installation: Serrated design ensures quick positioning, flexibility for uneven surfaces, and customizable thickness.

Installation and Maintenance

  • Inspect flange sealing surfaces for flatness and cleanliness

  • Select the appropriate gasket based on pressure, temperature, and medium

  • Position gasket properly and tighten bolts evenly

  • Check sealing effect using pressure or leak detection

  • Regular inspection and timely replacement ensure optimal performance

Applications

  • Petrochemical Industry: Sealing pipelines, valves, reactors, and towers under high temperature and pressure

  • Power Industry: Flanges and steam turbines, preventing steam, oil, and water leakage

  • Mechanical Manufacturing: Compressors, pumps, gearboxes, and bearings for reliable operation

Conclusion

 

Serrated gaskets are a reliable industrial sealing solution with excellent sealing, high-temperature and pressure resistance, corrosion protection, and ease of installation.
