Vibration & Fatigue Analysis of Reciprocating Compressor Piping
Tracing recurring fatigue cracking at a small-bore connection to a resonance condition and closing it with a support redesign.
01 — ChallengeRecurring fatigue cracking at a small-bore connection
A client experienced recurring fatigue cracking at a small-bore instrument connection on reciprocating compressor discharge piping, with no clear root cause identified from previous inspections.
02 — ApproachField vibration data combined with FEA fatigue analysis
Field vibration data collection, a pulsation study per API 618, and FEA fatigue analysis of the cracked connection and surrounding piping were combined to identify the driving mechanism.

04 — Quantified ResultsBefore / After
| Parameter | Baseline | Result | |
|---|---|---|---|
| Peak vibration velocity | 32 mm/s | → | 6 mm/s |
| Root cause | unknown | → | resonance with 2nd compressor harmonic |
| Predicted fatigue life | weeks | → | >10 years |
05 — Business Impact
Eliminated recurring unplanned shutdowns that had cost the client an estimated $85K per incident in lost production.
