<p style="margin: 0in 0in 8pt; text-align: justify">Piping vibration is a major concern for any machinery equipment and might cause equipment outage, leaks, failures, noises, and explosion if it was not addressed properly, especially in processing plants. This paper outlines a case study of Flow-Induced Vibration FIV in a gas compressor piping system. The subject piping loop experienced excessive piping vibration readings due to high dynamic energy in the gas compressor piping. This vibration was present since twenty years ago. However, several engineering recommendations failed to resolve this excessive piping vibration. A methodological assessment approach was conducted to assess this vibration with different measures to identify the root cause. Additionally, Motion Amplification Camera technology was utilized to understand the piping loop vibration behavior. The assessment outcome that the presence of dead legs in the expansion loop causes pulsation in line. Additionally, the piping loop was also loosely supported on spring hangers, which created an unbalanced force in the piping system. The dynamic pressure in line was calculated and found to be above 5000 kg.m−1.s−2. According to the Energy Institute guidelines, this pressure was classified as a medium risk of fatigue failure. The subject piping vibration was controlled by stiffening the expansion loop supports. Adding lateral supports on the existing supporting system mitigated the chronic vibration piping issue piping. The piping vibration was measured after implementing proposed recommendations and observed a significant vibration reduction in the piping system. Ultimately, utilizing Motion Amplification Camera technology with systematic piping vibration assessment techniques proved very effective in resolving the machinery piping vibration issues.</p>

ASME 2021 Pressure Vessels & Piping Conference (PVP2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
