1) σVU |
= |
Minimum installed pressure (adaption) at room temperature (RT) |
|
2) σVO |
= |
Maximum installed pressure at RT |
|
3) m |
= |
Ratio of "Minimum gasket pressure under operating conditions σBU " to "Operating pressure = Internal pressure pi ", thus: m = σBU/pi |
|
4) σBO |
= |
Maximum gasket pressure under operating conditions at various temperatures |
|
5) bD |
