Abstract: The presented results of studying gas vibration and pulsation in «centrifugal blower - pipeline» systems allowed to obtain a more detailed understanding of the mechanisms of oscillation and interaction of hydrodynamic and acoustic gas surges in air gas channels of the centrifugal blower, T-branches, diffusers, bends, reverse and control valves as well as dead ends of pipelines. The studies allowed to develop methods and means for preventing increased vibration of pipelines. These were introduced in compressor stations of OAO «Gazprom» gas mains
