How can steam hammering be effectively eliminated?
Thread Content
At the time of design, no control valves were used for the steam pipelines; instead, pneumatic ball valves were used to open and close the valves, and severe air hammer noise could be heard every time heating took place. Do you all have any methods to improve this?
Controlling the on/off of steam pipelines directly with a on/off valve does indeed cause water hammer, especially when the valve is opened and closed too quickly. Therefore, if you don’t want to replace the on/off valve with a control valve, you can consider adding damping to slow down the speed of opening and closing the valve.
Adding a damping mesh behind the valve yields good results; however, air hammer doesn’t pose any problem – it just causes some noise.
Adding a steam trap in front of the pneumatic ball valve will solve everything
