4. Flanges: Allow cable to be looped around pipe on each
side of and adjacent to the fl ange. Heating cable must
maintain contact with fl ange when bending around pipe
fl anges to compensate for additional heat loss.
5. Refer to the product specifi cations sheet for minimum
bend radius for the specifi c cable type. Do not exceed
bend radius when completing installation.
Installation on Elbows, Supports and Flanges . . .
1. Install heating cable in accordance with Illustrations D,
E and F below. Secure heating cable to piping using
attachment tape.
2. Elbows: Locate the cable on the outside radius of an
elbow to provide suffi cient heat to compensate for the
added piping material. Secure the cable to the pipe on
each side of the elbow with attachment tape.
3. Pipe Supports: Insulated pipe supports require no
additional heating cable. For uninsulated supports, allow
two times the length of the pipe support plus an additional
40 cm of heating cable.
