Vibration Expertise

Pipes vibration

Pipe vibration phenomena can have major consequences on installation due to the nature of products inside it. Pipe vibration analysis allows to take into account this risk by evaluating gravity of the situation and failure or break down risks. 

When?

  • Pipe vibration seen with the eyes.
  • Line or support breaks phenomenon.
  • Repeted cracks on pipe or picking.
  • Instrumentation breaks or is disturbed.
  • Vibration spreading between machines.
  • Pulsating or transient phenomenon.

Why?

  • Avoid cracks, leaks or breaks linked to fatigue phenomenon.
  • Quantify and evaluate vibration levels compare to standards (critical level).
  • Define size and position of new supports or vibration dampers.
