A pipe heat tracing system protects ...
... pipes from freezing.
Pipe heat tracing systems from eltherm are used where industrial pipe insulation alone cannot prevent water from freezing. They provide frost protection as well as temperature maintenance and prevent liquids from freezing or pipes from bursting. A pipe heat tracing system consists of an electrical heating tape that is attached to the pipes. It is powered by electricity and by converting electricity: the desired heat is generated. Through the conversion of electricity into thermal energy (heat), hot water pipes, for example, are kept at temperature or liquids are protected from frost.
As a result, long downtimes, expensive damages, hazardous situations for people and environmental damage are avoided.

The different types of electrical pipe heat tracing
Reliable – powerful – efficient
- Self-regulating solutions: Self-regulating heating cables change their output independently and automatically depending on the ambient temperature. If the resistance increases, the output decreases and vice versa. This process prevents the heat tracing system to overheat, which means that there is no need for additional regulation. Self-regulating heating cables can cover a temperature range of up to 250 °C, depending on the design.
- Solutions with temperature limiters: Non-self-regulating heating cables such as parallel or serial resistance heating cables must be controlled with specific measurement and controlling technology (controllers and thermostats designed for respective heating cables). Depending on the ambient temperature, this technology switches the heating cable on and off. Ideal for applications requiring high flexibility and performance.
- Mineral insulated solutions: These are particularly suitable for applications that require enormously high temperatures or extreme resistance to chemicals. Unlike plastic resistance heating cables or self-regulating heating cables, mineral insulated heating cables are designed for temperatures up to 1000 °C.


Applications of pipe heat tracing
The use of a pipe heat tracing system can prevent pipes, pumps and valves from freezing or even bursting at low temperatures. Mainly, eltherm pipe heat tracing systems are used in industrial facilities:
- Water and sanitary pipelines
- Chemical and petrochemical industry
- Oil and gas industry
- Food industry
Installation of the pipe heat tracing system
Basically, the installation of the pipe heat tracing depends on its constructional design. In most cases, however, it is wound around the pipe from the outside or, alternatively, laid vertically along the pipe. It is important to ensure that the pipe heat tracing system is only installed after all other works have been completed. Only professionally trained personnel can guarantee proper installation and consequently ensure that the heat is optimally distributed along the pipe.

FAQ
An electrical heat tracing system is used wherever heat loss or snow and ice must be prevented.
In general, a pipe or tank heated with electrical heat tracing should be insulated for reasons of cost-effectiveness. All common insulation materials can be used as insulations. The most commonly used insulations are mineral wool or PU foam - the choice of insulation depends on the temperature and operating conditions.
It is not allowed to mount a heating cable without insulation directly onto the pipe.
In general, there are no problems with heating plastic pipes. However, to improve heat conduction, the use of special aluminum strips is additionally recommended.
