What is Electrical Heat Tracing (EHT)?
Electrical Heat Tracing (EHT) is a system used to maintain or raise the temperature of pipes, vessels, or equipment using electrically powered heating cables.
It’s often installed along pipelines or tanks to prevent freezing, maintain process temperature, or ensure fluid viscosity in industrial plants.
Basic Principle
Electrical Heat Tracing works by:
- Running heating cables (resistance wires) along the surface of pipes or tanks,
- Covering them with thermal insulation, and
- Controlling the temperature using thermostats, sensors, or controllers.
When electricity flows through the cable, it generates heat due to electrical resistance — this heat is transferred to the pipe and keeps the process fluid inside at the desired temperature.
