The required minimum clamp load for a sealing function FKP considers the gasket in the calculation of the required minimum clamp load FKerf (R2).
The following options are available:
No gasket: there is no gasket in the load flow of the bolted joint for which a clamp load is necessary.
Gasket with internal pressure: there is a gasket, and the clamp load for the sealing function is calculated with the maximum internal pressure pimax to be sealed and the sealing surface AD.
User specified: direct numerical specification of the required minimum clamp load for the sealing function FKP.
In the following figure, a gasket is shown on the left side which is not in the force flow of the bolted joint and is therefore not relevant for the bolt calculation. On the right side, however, the gasket is in the force flow and should be taken into account in the design and calculation of the bolted joint.
