Pipe Heat Trace Cable Calculator - Quick and Easy Results
https://www.punchlistzero.com/heat-trace-cable-calculator/
Pipe Heat Trace Cable Calculator. Heat tracing on a pipe is most efficient when the pipe is properly insulated. The heat loss from a pipe depends on the pipe size, external insulation type, thickness of the insulation, and overall temperature gradient. For any heat tracing application, use this calculator to first determine the expected heat loss. Heat tracing can then be applied to …

Step 1.Calculate ΔT ΔT = Tm - Ta English = 40ºF - (-20ºF) = 60ºF Metric = 4.4ºC - (-28.9ºC) = 33.3ºC Step 2.Determine Pipe Heat Loss Find QP in Table 1 (page 2) for the nominal pipe size and insulation thickness based on ΔT. For example, for a 3" (76 mm) pipe with 2" (51 mm) insulation and ΔT = 60ºF (33.3ºC), the value for QP is 5.5 W/ft (10.8 W/m).

The Basics Of Electric Heat Trace Technology - CrossCo
https://www.crossco.com/resources/articles/the-basics-of-electric-heat-trace-technology/
The electric heating is achieved by utilizing a resistant element that is run alongside the piping or vessel. Current heat trace technology utilizes a self-regulating polymer that controls the wattage of the element. When the ambient temperature drops, the polymer creates conductive pathways that allow current to flow and heat to be produced.
