What vibration for a piping system still is acceptable?
And let me know the best practices & the references applied here please.
Thanks.
Piping Vibration Acceptance Criteria - References
Re: Piping Vibration Acceptance Criteria - References
Energy Institute (EI) Guidelines is the reference for the avoidance of vibration induced fatigue failure in process pipework. This is THE standard for the oil and gas industry. It uses a Likelihood of Failure (LOF) approach.
For most process piping, vibration is measured in RMS velocity (mm/s or in/s). A common "Rule of Thumb" for general screening is:
Target (Safe): <12.5 mm/s (0.5 in/s).
Concern (Marginal): 12.5−25 mm/s (0.5−1.0 in/s). Requires monitoring or study.
Danger (Corrective Action): >25 mm/s (1.0 in/s). High risk of fatigue failure.

Can you please share with me details of this reference?
