1.4 WHERE DOES PIPING VIBRATION COME FROM?
Two main factors affect vibration: the strength of the excitation and the flexibility of the piping system. Therefore, there are always two methods to solve piping vibration problems: reduce the level of excitation to which the piping system is exposed or support the piping systemso that it can withstand the applied dynamic forces.
The excitation mechanisms that cause vibration originate from three main sources:
Acoustic/pulsation – time-varying changes in fluid pressure
Momentum – time-varying changes in fluid density and velocity
Machinery – unbalanced forces from operating machinery.
