    Now you know the natural frequency of the pipe you ask your vibration techs to take a vibration measurement on the pipe when it’s in operation. If the frequency is the same as your calculated frequency, then the pipe has a resonance problem and the next step is to identify what is the force that is exciting the natural frequency.

    Piping Vibration: Causes and Effects – What Is Piping: All …

    Piping Vibration can be defined as a continuous to and fro motion from an equilibrium position. Piping vibration problems cause serious integrity risks to operating plants; both onshore and offshore production facilities. The vibration of the Piping System can cause fatigue failure on process piping and small branch connections and reliability problems on equipment.
