Pressure changes in steam pipelines
Thread Content
The steam pipeline is equipped with three pressure transmitters: two measure the pressure in the main pipes, and one measures the pressure behind the control valve. During normal operation of the system, the pressure behind the valve can suddenly increase by 20–30 kPa, while the pressures of the other two transmitters remain unchanged. The control valve is installed at the bottom of the U-tube, where there is a lot of water accumulation; as a result, the recovery of condensate is poor, and little condensate is discharged outside under normal conditions. May I ask, is this increase in pressure closely related to water accumulation? ? ?
Could it be due to water hammer? ? @Crazy Snail @leo_0088 @Logistics Engineer @ylb913
Yes, will it cause pressure to rise?
Ask the original poster: is this superheated steam or saturated steam?
I wonder if your pressure sampling points are set in this way?
The water accumulation here is likely to be saturated steam; if it were superheated steam, the degree of superheating would be quite low
Stagnant water turns into vapor. It is recommended to strengthen dehydration; water in the steam system can cause significant harm
If there’s water accumulation, it should lower the pressure, right?
