If the diameter of the main steam pipe is too small, resulting in a low steam flow rate, could this cause water hammer? For example, if the steam main has a diameter of DN250, the steam flow rate is 4.73 t/h, and the steam conditions are superheated steam at 250°C and 1.0 MPaG, will this cause water hammer?
Large pipe diameter results in low flow velocity; poor water repellency can lead to water hammer
Superheated steam does not produce condensate water during normal operation. Just be careful when warming the pipe.
Is flow rate related to pipe diameter? If low flow rates do not cause volume condensation, the formation of condensate water will not result in water hammer. Water hammer occurs only when the condensed water generated by holding back volume cannot be discharged, resulting in a two-phase flow.
