How are the outdoor components of northern installations, such as pumps, storage tanks, and pipelines, insulated to prevent freezing? What about the South?
The equipment is insulated with insulation materials or equipped with jacket heating; the pipes have heating tubes and insulation materials, though this is generally not necessary in the south
For insulation, aside from small instrument pipelines, instrument valves, and special pipes which can be insulated using electric heating, the rest are typically wrapped in glass wool; it is also necessary to ensure that the fluid has a certain flow rate. Otherwise, they will all get frozen damaged. It is necessary to keep the insulation layer dry and protected from wind. If possible, it can be heated with steam pipes. Remember one thing: any unused static/dynamic equipment, pipes, and valves must have all moisture removed, preferably by using gas to blow it out. Repeated verification must not be overlooked.
If only insulation materials are used for heat retention, and the equipment and pipes stop operating for about 10 hours at a time with intermittent operation, will the equipment and pipes freeze?
If the equipment and pipes operate intermittently, is insulation sufficient? The device keeps turning on and off, and it’s not possible to drain all the water from the equipment and pipes every time; moreover, there is no way to drain that water. Have you encountered such a situation?
After parking, the pump can be used for circulation to ensure that the material in the pipes remains in motion
Freezing detection lines are generally installed for circulating water and similar systems
The equipment is insulated on the outside, and intermittent heating is provided; these aspects are taken care of by the design firms. All you need to do is carry out the instructions – for example, check whether the circulation water valves are slightly open, and whether there are traps at the steam ends that lead back to the return water or that discharge water to the drain
