A physical fundamental principal states that all transportation of heat goes from warm zones to cold ones.

This means that for example pipes that are surrounded by low temperatures emit heat through the insulation. The size of the heat loss is depending on the diameter of the pipe, the thickness of the insulation, the material and the difference in the temperature between the pipe and the surrounding. If the heat loss is large enough there is a risk that the liquid in the pipes will freeze or be damaged in some way.

If ice formed in the pipes there is a risk that the pipes will freeze to.

To prevent ice formation in the pipes due to too low and ambient temperature an easy and effective method is to apply heating cables on the pipes or inside them.

The purpose is not to heat the pipe but to compensate the heat loss in the insulation.
Examples of applications:

Water- and waste pipes which are not placed in a frost proof depth.

  • Drainage pipes
  • Hot well pipes from refrigerating machines.
  • Control tubes.
  • Tanks and cisterns can also be frost protected by the same method.
