Issues regarding the prevention of equipment freezing in winter
Thread Content
I would like to ask everyone: if there is water in a pipe or heat exchanger (such as a U-tube), but not enough water to fill it completely, could the equipment freeze and crack in winter? Does anyone have experience in this area?
Hurry up and find a way to keep it warm; if it freezes, it will be too late. In severe cases, serious accidents could happen,,, To obtain the relevant methods, it is best to send targeted schematic diagrams. For reference.
