FAQs
1. What are the key factors to consider when choosing a gasket material?
The key factors include operating temperature, pressure, chemical compatibility with the fluids involved, and required durability. Consider the environmental conditions and the specific properties needed for the seal.
2. What is the difference between a metallic and a non-metallic gasket?
Metallic gaskets offer superior strength and high-temperature resistance but are less flexible. Non-metallic gaskets provide better flexibility and are often more cost-effective but have lower temperature and pressure limits.
3. How do I determine the appropriate gasket thickness for my application?
Gasket thickness depends on the surface finish of the mating flanges, the operating pressure, and the gasket material’s compressibility. Consult manufacturer specifications or engineering guidelines for accurate sizing.
4. What are some common types of gasket failures, and how can they be avoided?
Common failures include blowouts, leaks, and premature degradation. These can be avoided by choosing the correct gasket material and size, ensuring proper installation, and maintaining appropriate operating conditions.
5. What are the advantages of using gaskets made from non-asbestos materials?
Non-asbestos gaskets eliminate the health hazards associated with asbestos. They also offer comparable or superior sealing performance in many applications while being environmentally friendly.
