Issues with shutdown purging
Thread Content
During shutdown purging, how should flow meters and control valve assemblies be purged? I hope to receive guidance from all the teachers. Thank you!
The control valve was removed and a bypass was created; the flow meter was also removed and a bypass was installed; the valve at the base of the pressure gauge was closed
The flow meter and control valve should be removed and short-circuited
The control valve can be disassembled and equipped with a baffle for purging via a bypass line; the mass flow meter must be removed. In cases where there is a bypass line, a fast-line is used, while in the absence of such a line, a short section is used as a substitute
