Corrugated Metal Gaskets are made from metal sheets formed into regular corrugations by machining or pressing. The surface is typically covered with a soft sealing material such as graphite, PTFE, or non-asbestos materials to enhance sealing performance.
Performance
- elastic deformation of the corrugations, providing excellent resilience and resistance to creep
- minor flange surface irregularities and perform effectively at relatively low seating stresses
- High-temperature resistance depends on the selected metals and facing materials
- Various corrugation profiles and covering layers can be chosen to suit different applications
Advantages
- Excellent recovery, suitable for repeated use
- Stable sealing performance with relatively low flange surface finish requirements
- Can be combined with a wide range of facing materials to suit various fluids and environments
- Relatively low manufacturing cost with high cost-effectiveness
- Particularly suitable for heat exchangers, manhole covers, valves, and other medium-pressure applications
