Hydraulic force
After the initial bolt-up, the flanges are subjected to operating pressure and temperature. The pressure, if internal will create a force opposite to that of bolt- up. If external, the force is additive to the bolt load.
What is flange force?
Forces Acting on a Gasket
In a flange assembly, the gasket is placed between two flanges, which are then clamped together with bolts, studs, or other clamping devices. In this example, the bolts are creating a clamping load, or bolt force, which compresses the gasket. ... This force is called hydrostatic end force.
How do you find the force of a flange?
Calculate the Z vale of the compression flange only. Divide the moment by the Z value to get a stress. Multiply the cross sectional area by the stress. That should give me a maximum applied force.
