The weather has been extremely cold lately! !

The weather has remained cold recently. How well have you carried out frost protection measures? Has there been any unexpected damage to equipment or pipelines in your facility due to freezing? Let’s talk about it and give everyone a reminder! ! :lol

It would be better to change the title to “How to Prevent Freezing and Condensation in Case of Sudden Drops in Winter Temperatures”. Generally, all heat tracing should be activated before the first temperature drop in winter, and a thorough inspection should be carried out to ensure that air and water are discharged from the lowest points. When temperatures drop sharply, attention must be paid to steam tracing, as water can accumulate in some sections of the tracing lines as a result of the lower temperatures. If this water is not removed promptly, it will eventually freeze the tracing lines, and the pipelines that are meant to be insulated are also at risk of freezing. Therefore, it is important to check every morning whether steam is present at the lowest point of the heat tracing wire. For hot water tracing, the temperature of the inlet and outlet water must be checked at the beginning of each shift; if necessary, a small amount of steam can be added (although this is generally not allowed). The cooling water line of outdoor pumps can easily freeze if not properly managed after the pump is switched to standby mode. The instrument air line also needs to be opened for inspection, to prevent water from entering the instrument air and affecting the proper operation of the control valves. . . . . There’s nothing else that comes to mind for now. It would be better if the original poster posted the contents of their current checks here for everyone to share. Help each other fill in the gaps.

Tasks to be carried out for anti-freezing and anti-condensation in winter: 1. Activate all heating systems and conduct a thorough inspection to ensure condensation is drained from the lowest points. 2. The cooling water valve of the pump should be slightly opened. 3. Regularly drain condensate from the bottom of the instrument air tank. Prevent water from entering the instrument air; 4. The hot oil pump must be in a preheated state. 5. Outdoor instruments should be coated with insulating fluid or equipped with steam tracing. 6. The waterline of the device should be slightly open to prevent freezing and cracking. 7. The emergency oil return line of the device must be purged continuously to ensure steam flow. 8. When going out for inspections, a safety helmet must be worn to prevent ice spikes. 9. To save energy, do not discharge under pressure. 10. Do not stop supplying liquefied gas; when cleaning with alkali for liquefied gas, avoid using alkali solution to prevent line condensation. 11. The water supply to the water seal tank in the torch area shall be changed to running water. There is too much work to be done; please continue the discussion.
