An expansion joint acts as a piston by the forces arising from the internal pressure.To prevent the pipes from damage they are to be properly anchored in order to take care of these reaction forces (Fr).

The Reaction force of an expansion joint is calculated by the following formula:

Fr = Q x P x 0.01

Fr = reaction force in kN.

Q = effective cross sectional area in cm2.

P = actual pressure in bar or kp/cm2
