Heat Tracing for Pipes: What We Need to Size Your System

Heat Tracing for Pipes: What We Need to Size Your System

Heat tracing cable keeps pipes and vessels at temperature — freeze protection in winter, process maintenance year-round. Correct sizing depends on your site, not just the catalogue. Here is the information to include in your enquiry so the system is sized right the first time.

1. Pipe diameter and total traced length

Nominal diameter plus the full run to be traced, including valves, flanges, and supports if they need coverage. Tracing is supplied in custom lengths, so accurate layout dimensions prevent shortfalls and waste.

2. Insulation type and thickness

Heat loss — and therefore cable selection — depends heavily on what covers the pipe. Note the insulation material and thickness, or state clearly if the run is uninsulated.

3. Temperature to maintain

The lowest ambient temperature the system must handle and the pipe temperature to hold. Self-regulating options with automatic control suit many freeze-protection and maintenance duties.

4. Available supply voltage

Standard offerings cover 220 V installations. Confirm what your site provides so the cable and any controls match.

5. Site conditions

Outdoor exposure, washdown areas, hazardous classifications, and whether steam tracing is unwanted at the site — each of these steers the cable and accessory choice.

Send these five details with your pipe layout or photos. Sales will confirm the cable type, total length, and controls, and quote accordingly. For simpler electric heating needs, also see the trace heater range.
