The Mechanics of a Bolted Joint – May the force be with you
The Bolt Load tries to keep everything together while the Hydrostatic End Force tries to push the flanges apart which stretches the bolts and can lead to lower gasket compression and the Blow Out/Internal Pressure forces the gasket out of the flange.
Approximately 75-85% of all bolted flange joint failures relate to uncontrolled gasket installation and joint assembly practices.
The Function of Bolts, Studs & Nuts
The clamping capability of a bolt is determined by its elasticity or ability of the bolt to return to its original shape after being deformed; making bolt selection very important.
Because friction works against you, it is important to apply lubrication to both the bolt and nut threads, as well as the nut flange facing in order to reduce the friction.
Effects of Tightening
Effects of over tightening reduces the gasket contact area and can cause the gasket to crush toward OD. This allows fluid to penetrate the gasket ID leading to deterioration and will result in leakage.
Effects of under tightening allows fluid to penetrate gasket ID leading to deterioration of the gasket. Underloading can lead to blow-out or leakage. Unloading caused by temperature or pressure cycling can have the same effect.
Proper Gasket Installation
Make sure your system is at ambient temperature and depressurize and inspect the flange condition & alignment, the condition of fasteners and make sure flange surfaces are clean. Always use a new gasket and never use more than one gasket in a flanged joint at a time.
Proper Gasket Installation will increase the life of the gasket, reduce your maintenance costs and reduce leakage.
