Thermon MIQ Mineral Insulated Heating Cable v.2 - Manual (Page 6)

MIQ TM Mineral Insulated Heating Cable
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 sufficient 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 ad-
ditional heating cable. For uninsulated supports, allow two
times the length of the pipe support plus an additional 15”
(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 flange
when bending around pipe flanges to compensate for
additional heat loss. In potentially explosive areas, it is
recommended to secure MIQ cable with stainless steel
banding at all flanges or any other irregular shaped equip-
ment.
5. Minimum bend radius is 6X cable OD. Do not exceed
bend radius when completing installation.
