Targeting the Right Gasket Stress
Many studies have been completed which show that long-term sealing of bolted connections is all about gasket stress. To be more precise, it is about attaining the needed stress, and maintaining that stress in the face of the relaxation that can be anticipated in the joint.

The two exchangers listed in the notes were chosen at random from the hundreds of heat exchangers that we have been asked to analyze. They weren’t chosen because they are extremes, and simply demonstrate the natural variations that exist among code-designed heat exchangers. In both of these examples, we have used the artificially selected value of 50% of the minimum stud yield strength as our “target”.
