Expert Guide to Selecting Metal-toothed Corrugated Gasket Materials

When choosing a metal-toothed corrugated metal gasket for industrial applications, it's crucial to consider the specific medium and operating conditions to ensure optimal sealing performance. This guide provides insights into selecting the appropriate gasket material, focusing on five key factors: chemical compatibility, temperature resistance, pressure endurance, surface finish, and vibration resistance.

1. Chemical Compatibility

Understanding the chemical nature of the medium is essential for selecting a gasket material that resists corrosion and degradation.

Material Chemical Compatibility Comparison

Material	Chemical Resistance	Temperature Range	Pressure Rating	Surface Adaptability	Vibration Resistance
Graphite	Excellent with acids, alkalis, solvents	-200°C to +850°C	Up to 5000 psi	Rough or smooth surfaces	Moderate; may require extra support
PTFE	Inert to most chemicals; low creep resistance	-200°C to +260°C	Up to 3000 psi	Smooth surfaces only	Low; not suitable for vibration
Flexible Graphite	Good chemical resistance; high-temperature tolerant	-200°C to +850°C	Up to 5000 psi	Rough or smooth surfaces	Good; suitable for dynamic systems
ePTFE	Excellent resistance to aggressive chemicals	-240°F to +500°F	Up to 5000 psi	Smooth surfaces	Excellent; ideal for vibrating systems

2. Temperature Resistance

Gasket materials must withstand the operating temperature to maintain sealing integrity.

Temperature Performance Table

Material	Min Temp	Max Temp	Pressure	Chemical Resistance	Surface Adaptability	Vibration Resistance
Graphite	-200°C	+850°C	Up to 5000 psi	Excellent	Rough/smooth	Moderate
PTFE	-200°C	+260°C	Up to 3000 psi	Good	Smooth only	Low
Flexible Graphite	-200°C	+850°C	Up to 5000 psi	Good	Rough/smooth	Good
ePTFE	-240°F	+500°F	Up to 5000 psi	Excellent	Smooth	Excellent

3. Pressure Endurance

High-pressure applications require gaskets that can maintain sealing force without failure.

Pressure & Material Comparison

Material	Max Pressure	Temperature Range	Chemical Resistance	Surface Adaptability	Vibration Resistance
Graphite	5000 psi	-200°C to +850°C	Excellent	Rough/smooth	Moderate
PTFE	3000 psi	-200°C to +260°C	Good	Smooth only	Low
Flexible Graphite	5000 psi	-200°C to +850°C	Good	Rough/smooth	Good
ePTFE	5000 psi	-240°F to +500°F	Excellent	Smooth	Excellent

4. Surface Finish

The surface finish of flanges affects sealing performance.

Surface Adaptability Comparison

Material	Surface Type	Max Pressure	Temp Range	Chemical Resistance	Vibration Resistance
Graphite	Rough or smooth	5000 psi	-200°C to +850°C	Excellent	Moderate
PTFE	Smooth only	3000 psi	-200°C to +260°C	Good	Low
Flexible Graphite	Rough or smooth	5000 psi	-200°C to +850°C	Good	Good
ePTFE	Smooth	5000 psi	-240°F to +500°F	Excellent	Excellent

5. Vibration Resistance

Dynamic systems require gaskets that can maintain sealing integrity under vibration.

Vibration Resistance Comparison

Material	Vibration Resistance	Max Pressure	Temp Range	Chemical Resistance	Surface Adaptability
Graphite	Moderate	5000 psi	-200°C to +850°C	Excellent	Rough/smooth
PTFE	Low	3000 psi	-200°C to +260°C	Good	Smooth only
Flexible Graphite	Good	5000 psi	-200°C to +850°C	Good	Rough/smooth
ePTFE	Excellent	5000 psi	-240°F to +500°F	Excellent	Smooth

Conclusion

Selecting the appropriate gasket material involves balancing chemical compatibility, temperature resistance, pressure endurance, surface finish, and vibration resistance. This comprehensive comparison enables industries to quickly identify the best metal-toothed corrugated metal gasket for their operational needs.
