Selection Chart 1.2.1: Metallic Piping
Example on how to read the
Metallic piping chart
Example: A 4" diameter metallic pipe that
will be insulated with 1" fibreglass must
not freeze even with a minimum expected
ambient temperature of -12°C (10°F).
Refer to chart 1.2.1 .
Using the column for the -12°C (10°F)
ambient temperature, the section of
the table that corresponds to 1" thick
insulation and the row indicated for a 4"
diameter pipe in
chart 1.2.1
identifies 1
pass of TTS™ Self-Regulating Heating
Cable-5 as the proper cable to use.
Note: Chart may also be used with polyisocyanurates
or mineral wool of the same thickness.
