How can water hammer noise occur in dead sections?
Thread Content
Water hammer effects were observed in the dead sections of the pipeline on site; the system pressure was around 20 bar. The point where water hammer occurred was less than 1 meter away from the downstream isolation valve, which is a wedge-shaped gate valve. Inspections revealed no internal leakage in the valve. Has anyone else encountered this phenomenon? What could be the cause?
When water hammer occurs, the water hammer wave spreads throughout the entire pipeline network, so pressure increases even at the \"dead ends\" as well. Pipeline water hammer can be simulated and analyzed using software.
