Bolt tensioning calculation
WebGeneral practice is to use 25%, 50% or 100% bolt tensioning. 100% tensioning The recommended is 100% tensioning. This means, that all bolts in the flange will be tightened simultaneously, achieving uniform compression using just one pressurization of the tensioners followed by a check pass. WebBolt Elongation by Turn Formulas and Calculator per. MIL-HDBH-60; Design Considerations. The first requirement in determining the amount of torque to apply is a knowledge of the desired bolt stress. This stress based on the yield strength of the bolt material. It is recommended that the induced stress not be allowed to exceed 80% of the …
