Things related to keeping warm and preventing freezing in winter?

The company uses two types of water at different temperatures for heat exchange and cooling, both located in shaded areas. The temperature difference between the two types of water was 10 degrees; during operation of the water pump, the pressure gauge of the pump connected to the water with the higher temperature was damaged by freezing, while the pump connected to the water with the lower temperature remained unaffected. What is the reason for this? ?
Heat expands, cold contracts! I guess that’s the principle behind it! Things that tend to happen when the temperature is too high!
Reply to 2# sofnngs: One water temperature is 15 degrees and the other is 5 degrees; it’s impossible for the water to be that hot! It shouldn’t be right
During the operation of the water pump, a gauge with a higher temperature rating was damaged by freezing. Is it located in a drafty area? But under normal operating conditions, it should not be like this. I hope to make it clearer.
Reply 4# libamen is on the shaded side; opposite it is a wall. In the middle are two storage tanks; to the east, there are three 15-degree water pumps, with two in operation and one as a backup, while to the west, there is one 5-degree water pump, with one in operation and one as a backup.
Is it confirmed to be damaged by freezing? ? ? ? Is the reply length not enough?
Are there valves and pressure gauge elbows in front of the pressure gauge?
Reply to 3# ggq0516: The temperature isn’t very high, so it can’t be that issue. I can’t think of any other reason, haha!
This has little to do with the water temperature; it’s probably because the pressure gauge’s pressure lead is too long. Insulation should be added, which will improve the results. We have similar situations here as well
Reply to 7# Waiter: There is a pressure gauge bend, valves, and a drain port below the gauge as well. Remove the watch and blow on it with steam to get ice out. .
I think this has little to do with the temperature of the medium; the medium at the pressure gauge location is stationary. If there is no heating or insulation, a slightly lower temperature on site will definitely cause freezing, leading to damage to the pressure gauge. If one of the two tables is damaged while the other is not, it simply means that their heating and insulation conditions are different
