The Spring Festival is approaching; let’s discuss equipment anti-freezing! ! !
Thread Content
The Spring Festival is approaching, and we need to arrange for personnel to drain the water from the reaction vessels and the jacket water of the condensers. The pipes make things complicated; it’s necessary to use vacuum to remove the water, including that in the steam pipes, and to empty all the water from the vacuum pumps as well! Is there anything else anyone would like to add?
I have done this work before; all steam pipes need to be inspected regularly, water pipes must remain in flow, and the insulation for steam systems should be set to a higher level, and so on. The most important thing is to have a sense of responsibility, to conduct regular inspections, and to address issues promptly
Gaskets should be kept ready near each device; as soon as freezing occurs, steam should be applied immediately for thawing. Action must be taken quickly, as the more it freezes, the harder it is to thaw – any issue detected must be addressed right away. Water in the instrument air can have serious consequences, so extra care is required
For steam and water pipes that are not in use, all the water within the pipes should be drained. In addition to the method mentioned by the person upstairs, nitrogen can also be used to blow out the water; opening the low-point drains and high-point vents makes it easier to drain the water. For pipes that are in use, it is also important to use drains to prevent freezing. For steam pipes, it is necessary to assign personnel to conduct round-the-clock inspections of the drains and traps, ensuring that the drains are properly opened and that the traps function correctly.
