Kammprofile gaskets (also known as serrated or grooved gaskets) are manufactured from a solid metal core, with concentric grooves machined on the sealing surface. The grooves are usually filled with a soft sealing material such as graphite, PTFE, or mica to enhance sealing performance.
Performance
- Suitable for high temperature, high pressure, and highly corrosive media.
- The serrated groove design provides strong radial sealing action when compressed.
- Combines the strength of metal with the resilience of soft filler materials.
Advantages
- Excellent blowout resistance, capable of withstanding pressure fluctuations and mechanical shocks.
- Maintains stable sealing performance under extreme temperature and chemical conditions.
- Requires relatively lower bolt load to achieve effective sealing.
- Commonly used in petrochemical plants, nuclear power, pressure vessels, and heat exchangers.
