Abstract

The strong vibration of the process piping behind the pressure regulator in a natural gas transmission station was stimulated under the large transportation capacity. The vibration parameters at key positions under the actual operating conditions, the excitation frequency of vibration source and the natural frequencies of piping were tested in the field to investigate the cause and severity of the vibration. In addition, the schemes for vibration reduction were proposed, and the actual damping effects after piping rectification were evaluated simultaneously. The results indicate that the maximum peak-to-peak value of piping vibration displacement and velocity are 0.76 mm and 44.84 mm/s respectively, which have drastically exceeded the maximum allowable thresholds. In addition, the response frequency of the piping, the excitation frequency of the vibration source and the natural frequency of the piping are all equal to 12.5 Hz. It shows that the intense resonance is caused by the coincidence of the excitation frequency of the vibration source and the natural frequency of the piping. The excitation source mainly comes from the strong pressure pulsation generated by the gas pressure regulator under the large transportation capacity. After adding the piping of pressure regulating valve T2 and shunting the piping of pressure regulating valve T1, the excitation frequency is reduced from 12.5 Hz to 8.5 Hz, and the vibration reduction efficiencies are between 62.4% and 77.2%.
