Putkisärölaitteita

Putkisärölaitteita, often translated as pipe chilling units or pipe freezing equipment, are specialized devices used to temporarily seal sections of pipes by freezing the liquid inside. This process allows for maintenance or repair work to be carried out on the pipe without the need to drain the entire system.

The principle behind putkisärölaitteita involves applying a refrigerant or a very cold fluid to the external surface of the pipe. This localized cooling causes the water or other liquid within the pipe to freeze, forming a solid ice plug. This ice plug acts as a temporary valve, effectively isolating the section of the pipe that requires attention.

These units typically consist of a refrigeration unit, a circulation system for the refrigerant, and clamping devices or saddles that are attached to the pipe. The clamps ensure efficient heat transfer from the pipe to the refrigerant. The effectiveness of the freezing process depends on factors such as pipe diameter, material, the type of liquid being carried, and ambient temperature.

Putkisärölaitteita are commonly employed in various industries, including plumbing, HVAC systems, industrial processes, and marine applications. They are particularly useful in situations where draining the system is impractical, time-consuming, or would result in significant disruption. Once the repair is complete, the refrigerant is removed, and the ice plug gradually melts, allowing the system to return to normal operation. Safety precautions are essential during the operation to prevent pipe damage due to the expansion of freezing water.
