Pipe Heat Loss Calculations

1.Basic Heat Loss: After determining the difference between the ambient and desired pipe maintenance

temperature, T

, use Table 1 to figure the basic heat loss for the pipe size and insulation thickness.

m

2.Insulation Adjustment: Using Table 2, find the type of insulation being used and its insulation factor.

Chromalox Cable Selection

1.Select Heating Cable Family: Based on the maximum maintenance temperature rating, maximum

exposure temperature rating, and area classification, select the heating cable family from Table 3. (See
Chromalox Heat Trace Cable Product Information Sheets for cable construction options, voltage ratings,
and wattage outputs available.)

2.Select Thermal Output Rating:

(a) For Metal Pipes – Use Figures 1, 2 or 4
(b) For Plastic Pipes – Use Figure 3 by finding the intersection of the calculated heat loss, Q

maintenance temperature, Tm. Select the cable with a thermal output that equals or exceeds QFat Tm.
