Thermon MIQ Mineral Insulated Heating Cable v.1 - Manual (Page 5)

INSTALLATION PROCEDURES
Installation on Elbows, Supports and Flanges . . .
1. Install heating cable in accordance with Illustrations
C thru E below. Secure heating cable to piping using
stainless steel tie wire or banding.
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 stainless steel tie wire or
banding.
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.

Note:
Slack cable can be taken up by running the cable on the outside radius
of the pipe elbows. Running the cable on the inside radius of the pipe
elbows will add slack to the cable.

4. Flanges: Heating cable should maintain contact with
fl ange when bending around pipe fl anges to compensate
for additional heat loss. In potentially explosive areas,
it is recommended to secure MIQ cable with stainless
steel banding at all fl anges or any other irregular shaped
equipment.
5. Minimum bend radius is 6X cable OD. Do not exceed
bend radius when completing installation.
