Winter Anti-freezing Experience Sharing Event

We’re busy trying to prevent freezing, and accidentally, one area after another freezes over, leaving us constantly busy dealing with the issues. Just as I put down the steam pipe, I have to pick up the stick again to break the ice – it’s not easy at all. “Hey hey hey… stop talking casually; the monitor has called you to go handle the anti-freezing task. ”Do you still remember that cold day? There was no moment of rest during the inspections outside; the heat tracing, which had been emitting heat just a moment earlier, would freeze up instantly, the cooling towers would become covered with ice and collapse, and the pump pipelines used for transporting materials would freeze as well…. It’s extremely cold; any part that isn’t properly protected will freeze up, which can lead to equipment damage in mild cases, or even accidents in severe cases. I have some clever tips for ensuring the safety of chemical plants through the winter. Whether it’s in the petrochemical, coal chemical, methanol, natural gas, hydrogenation, LNG, or other sectors, if you have effective anti-freezing solutions, please share them so that we can all learn from each other and ensure a safe winter.

Be diligent in using your hands to feel the heat tracing. Of course, it would be best to have a temperature gun. For the pump and cooler, the circulating water bypass is opened to a certain degree. For fire-fighting steam, a rubber hose is used for external drainage at the bottom; the isolation valve for steam that is not in use at the service station is closed, while the lower valves are kept fully open. In this case as well, a rubber hose is connected to the floor drain, with a certain degree of openness maintained. Temperature measurement of the air cooler; adjustment of the louver opening based on temperature, as well as starting and stopping the air cooler. The instrument air main pipe should be drained regularly. The pump should be turned over once per shift.
The anti-freezing plan can be detailed with the specific procedures, edited into a post, and shared to participate in the event. Summary post of the “Winter Anti-freezing Experience Sharing Event”: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1868874&extra=page%3D1
Lift up and support Haichuan’s activities!
Everyone should participate actively, learn from others’ experiences, make up for their own shortcomings, and reduce damage to the equipment
The heat tracing pipelines should all be integrated into the return piping system, and the vent line can be connected to the heat tracing line
