May I ask, for a steam pipeline with DN200, can an 8-character blind plate be used as a shut-off device during maintenance? The type where the system was still running before it was shut down

System isolation is also required to turn the 8-character blind plate around

How can a blind flange be removed if there is no isolation valve on the pipeline?
