Note Urecon offers a complete computer assisted engineering service providing such information as heat loss, time to freeze, fluid outlet temperature, minimum flow rates, tracing wattage required, heat gain, etc., all based on the specific requirements of each project. Heat Trace (Heat Tracing)The principle of heat tracing dates back from the early 1900s, when steam and fluid heat tracing techniques, were used to ensure the flow of petroleum (viscosity control) through pipelines . Although very rudimentary during the 1930s, electric heat tracing began to appear without dedicated equipment, controls or adequate materials. Heat Tracing of Piping Systems - Effective Steam TracingTypes of Heat Tracing Systems Effective Steam Tracing The Need For Steam Tracing Types of Steam Heat Tracing Determining Tracer Requirements Sizes and Lengths Benefits of Steam Tracing Versus Other Methods Heat-tracing systems can be divided into two broad classes, electric and fluid. Fluid heat-tracing systems utilize heating media at elevated temperatures to transfer heat to a pipeline. The fluid is usually contained in a tube or a small pipe attached to the pipe being traced. If steam is the tracing fluid, the condensate is either returned to the boiler or dumped. If an organic heat-transfer fluid is employed, it is returned to a heat exchanger for reheating and recirculation.

Electrical tracing . On the other hand, in electric tracing (Fig. 2) of the piping system, an electrical heating element transfers heat into the process fluid while running in physical contact along the pipe length. Heat is normally generated in an electrically resistive element. However, other effects like impedance, induction, skin conduction, etc can be utilized in electrical tracing . When to use heat tracing for fire protection?When to use heat tracing for fire protection?Special considerations should be made for tracing of water for safety showers and fire protection systems.
