Expansion Joint
Dimensional changes in piping and equipment, caused by variations in the working temperature of the piping system and the
pump, either by the temperature of the pumped fluid or by exposure to changing environmental conditions, result in large
magnitude stresses and forces that are transmitted to the pumping equipment and can damage it. That is why VOGT S.A.,
recommends the use of expansion joints as part of the piping system that connects to the pump, when conditions warrant it,
see figure 22.
Even though the absorption of axial movements, caused by temperature changes, is the main work performed by the
expansion joints, they also act as vibration isolators reducing the propagation of vibrations, produced by the operation of the
equipment, through the piping system and also act as compensators of lateral, angular and torsional movements.
