### Mechanical Natural Frequency - an overview |

Large piping vibrations are often caused by coincidence between the pulsation frequency and the mechanical natural frequency of the piping. It is essential to avoid this resonance condition. Adding damping to the piping by means of a hydraulic cylinder or a dynamic damper can be effective. However, it should be noted that piping vibration tends
