Electrical heat tracing is a method of applying heat to pipes, tanks, instruments & associated equipment using heating cables. The heating cable is used to heat a product as it flows through pipes/equipment and also to heat products contained within vessels. Electrical heat tracing is a method of applying heat to:
- Liquid for preventing freezing and reducing viscosity.
- An anti-condensation powder to prevent clogging, condensation on walls of the equipment.
- Gas that prevents hydration due to drops in pressure across pipework fittings such as valves.
The main use of the heat trace is to maintain the product at the right temperature to prevent processing problems, and is also useful for heating pipelines and equipment.
The general components of an electric heat tracer are:
- Heat tracing cables
- Junction Boxes for power/ end/splice/TEE
- Mounting stands and hardware
- Termination Kits
- Temperature sensors (RTD/Thermostat)
- Adhesive tapes
As part of the electrical heat tracing system, there are:
- Control/Distribution panel
- Transformer (optional)
- Power and control cables
- Earthing material
- Cable trays
- Glands and shrouds

Frequently Asked Questions
1. Electrical heat tracing: What is it?
Ans - An electrical system called a heat trace system is used to keep pipes and vessels at a certain temperature or increase it. By using a resistive element that is run alongside the piping or vessel, electric heating is accomplished.
2. Why is electrical tracing effective?
Ans - In order to achieve uniform heating along pipes, electric heat tracing uses cable that is intended to offer constant watts per unit of length. To guide the heat output toward the fluid inside, insulation is placed to all sides of the pipe but the pipe's orientation.
3. What is temperature control via electrical heat tracing?
Ans - The technique of checking and maintaining the temperature on tanks, pipes, valves, instrument panels, and other objects is known as electrical heat tracing. There is a lot more to an electrical heat tracing system than just the heating line. From design to installation, commissioning, and testing, Supermec offers a full system.
4. How much energy is required for electrical heat tracing?
Ans - Heat tape uses nine (9) watts on average per lineal foot.
