Blowing of steam pipelines for the turbine at the freezing station
Thread Content
After purging the steam pipelines in the freezing stations, rust may form if they are left exposed for an extended period. How can this be avoided?
Apply nitrogen protection, or keep steam flowing continuously.
If the time is not too long, the amount of rust that forms will not pose a threat to the turbine; if the time is too long, it is possible to use nitrogen for protection!
Once the steam purging is complete, single-unit testing should be carried out immediately
