Question - What Are Some Common Causes Of Gas Pipeline Vibration 20 Carbon Steel Line?
Answer -
Check / consider the following:
- 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.
- If the source is a tower, look for pressure cycling in the tower
- Look at critical flow through any control valve that may be in the line.
