Friction coefficient µG
The friction coefficient between gasket and flange surface was determined for different types of gasket materials in an ESA research project.
The gasket Flachdichtung SIGRAFLEX® Universal , Profil FD01, WS 3862, Dichtungsdicke 2 mm, Rev. 00 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:
| Temperature / °C | Friction coefficient |
|---|---|
| 20 °C | 0.22 |
