Anti-freeze heating cable problem?
Thread Content
The antifreeze and condensation period has passed, and the heating cable of the device has begun to be deactivated. I wonder how you should deal with the heating cable of the device during the non-antifreeze and condensation period? Our method is to close the main steam and condensate drain valves, and open the diversion to drain the water in the heating cable. In this way, it is necessary to ensure that the main valve does not leak internally. There are very few valves that do not leak internally. What should I do?
Refining oil depends on the medium in the pipeline, and it must be deactivated step by step from lighter oil to heavier oil.
Install double valves to prevent internal leakage. this is the best way
During non-antifreeze and condensation periods, we only turn on heating for heavy oils such as raw oil and oil slurry. The process of stopping heating is the same as mentioned on the second floor. Stop the light oil first, then the heavy oil.
