118. What Are Some Common Causes Of Gas Pipeline Vibration 20 Carbon Steel Line?
The upper pressure range and /or the smaller pipe diameters prompts me to investigate the possibility that the gas is reaching critical flow somewhere downstream within the pipe. When a gas gets to critical flow, sonic booms (producing vibration) are expected. In fact, one of the main means by which the additional pressure in the pipe is lost. If the source is a compressor, look for surging.
