Heat tracing is a system used to maintain the temperature of pipes, vessels and surfaces.
In heat tracing, an electrical heating element is fitting in physical contact along a length of pipe or across a surface. Heat generated by the element maintains the temperature of the surface. Typically, the pipe or surface is covered with insulation to retain heat loss. A robust heat tracing system often includes a thermostat, monitor and controller so that end users can track and adjust the temperature of the heated surface
Heat tracing is commonly used to prevent pipes from freezing, to maintain the temperature and flow of transported substances, and heat floors, driveways and parking lots.
