Frequently Asked Questions
Q: What makes Reinforced Graphite Gaskets superior to standard ones?
Reinforced gaskets include a metal insert or mesh that provides mechanical strength, preventing the graphite from blowing out under high pressure and resisting deformation during thermal cycling.
Q: Can Donit Grafilit Em be used in cryogenic applications?
Yes, high-quality reinforced graphite is capable of maintaining its sealing properties at extremely low temperatures, making it suitable for cryogenic services.
Q: How does the reinforcement affect the compressibility of the gasket?
While the reinforcement adds strength, the gasket is engineered to maintain sufficient compressibility to ensure a tight seal against flange faces without requiring excessive bolt torque.
Q: Which industries commonly use these rubber and graphite components?
They are widely used in the petrochemical industry, oil and gas refineries, chemical plants, and power generation facilities where high-temperature sealing is critical.
Q: Is the reinforced graphite gasket resistant to oxidation?
Graphite naturally oxidizes at high temperatures in oxygen. However, the reinforced structure helps maintain the physical seal as the material ages, though specialized inhibitors can be used for extreme cases.
Q: How do I choose the correct size for a Flange Insulation Gasket Kit?
You should refer to the flange standard (e.g., ASME or DIN) and the nominal pipe size (NPS). Our technical team can provide customized kits based on your specific piping diagrams.
