Vibration in steam condensate pipes
Thread Content
Why does the condensate pipe of a steam heater often vibrate in the first ten-odd minutes after it starts heating?
As a supplementary note, the steam heater has a liquid collection tube; the liquid level in this tube drops significantly after heating is completed before rising again. Could it be that steam enters the tube during this drop, and the vibrations that occur during the next heating cycle are caused by the gas present in the tube?
It’s possible that there was steam in the condensate pipe, causing water hammer. When we first started operating, we also experienced water hammer in the condensate pipe, so we simply discharged the water on site
Why does the condensate pipe of a steam heater often vibrate in the first ten-odd minutes after it starts heating? Liquid hammer is generated
It’s just a gas-liquid two-phase flow; as the pressure of the high-temperature condensate decreases, steam is generated
