What is Electrical Heat Tracing

Electrical Heat Tracing is an engineered system designed to maintain or protect process piping, equipment, vessels, and instruments at defined temperatures and within specified design criteria.

An electrical heat tracing system is much more than just the heating cable. A large majority of
commercial electrical heat-tracing systems are of the resistive type and take the form of cables that are placed on pipes.

When electric current is flowing through the resistive elements, heat is created in proportion to the square of the electric current and the resistance of the elements to the current flow.

Industrial applications of heat tracing may be found in the oil and gas production, storage facilities, petrochemical plants, refineries, pharmaceutical production, power generation, water and waste treatment plants, food processing, plus many others. Solutions using heat tracing can be provided for freeze protection, or for temperature maintenance duties.

Frost Protection

Heat tracing for frost protection ensures that the minimum temperature is not exceeded at any one point in time. Application areas are often supply lines. If these supply lines freeze, it would not only result in interruption to production, but would also attract considerable damage to the entire pipeline system. A competent heat tracing system would ensure safety and reliability and allow operations to run smoothly.

Some other typical application can include:

Frost protection for roof tops in cold countries.

Temperature Maintenance

Heat tracing systems for temperature maintenance have a wide range of applications. It ranges from the preservation of the fluidity of a medium to support for efficient production.

Some typical applications can include:

Gasoline oil, liquid asphalt, chemicals, chocolate, and vegetable oils.

Heat Up

Some heating processes require at times a particularly high performance/temperature, such as when restarting a column or a reactor. Once the target temperature is reached, the power can be reduced to regular temperature maintenance level. This flexibility allows the heat tracing system to be versatile and only use more energy when necessary.

Benefits of Heat Tracing

Electrical Heat Tracing are the most efficient type of heating as compared to for example, steam tracing. The energy supply can be brought to any location with virtually no losses in energy to be converted into heat. You can find out more about electrical heat tracing vs steam tracing here.

If service is required, the area that is to be repaired is easily accessible and can be maintained with little effort after switching off the heating system.

Electrical heat tracing systems are easy to design, are rugged and easy to operate when installed by a competent expert specializing in the heat tracing industry.
