Chromalox PRECISION HEAT AND CONTROLElectrical Heat Tracing SystemsDesign GuideCONTENTSINTRODUCTIONThis Design Guide provides a step-by-stepapproach for the Design , specification, and selec-tion of a bill of materials for an electric heat tracing system. Electric heat tracing systems aredesigned to make up for the heat lost fromprocess system equipmentthrough the thermal some cases, the heat tracingsystem can be used for systemheat-up at initial startup or after apower information in this Design Guide will allow theuser to Design , specify, and select a complete bill ofmaterials for freeze protection or process mainte-nance applications for a piping system or tank. Byfollowing the steps in this Guide the user can easilyselect a complete bill of materials forthe system, including heating cable,connection accessories, andtemperature OFThermal Design - Pipes: . . 1Thermal Design - Tanks:. . 6Heating Cable Selection: . 8Mineral Insulated CableDesign.
The first step in designing a heat trace system is to determine the heat loss from each pipe or tank to be traced. Collect the following data for each pipe (for tank applications go to page 6). Then fol- ... in W/ft and W/m Based on Temperature Differential and Insulation Thickness Nominal Pipe Size, in. (ID)
