How do you prevent freezing and condensation in winter?
Thread Content
Winter is approaching; fellow sailors, please share how you prevent freezing in your equipment. The main tasks in our workshop include: 1. Utilization of various types of heating methods, including steam heating, hot water heating, and electric heating ； 2. Both loops of the circulating water system are turned on ； 3. All new water systems that can be shut down should be purged and isolated using blind flanges ； 4. Felt covers have been added to all the drain #covers ； 5. Check the steam trap every two hours ； 6. Standby pump in thermal standby mode. ......
1. If heat tracing is available, use it； Heat tracing is applied to this section. 2. Slightly open the cross-line at the inlet and outlet of the circulating water ； 3. For fresh water, close the root valve underground, downstream of the valve. Vent at the lowest points of the subsequent branches ； 4. Close the valve of the fire pump to release water ； 5. Connect the heating pump circuit for the standby pump ； 6. Some oil and gas pipelines that were shut down but had been filled with fluid during the current year were purged using oil and gas. 7. Cut water at the lowest point in some non-flowing areas. 8. Try to open some cross-lines under certain conditions. 9. Establish a circulation for some of the towers that have been shut down, as appropriate. 10. The cooling water of the pump is very prone to clogging, and it should be a focus of inspections. 11. Continuous flow at the end of the decommissioned recycled water system.
