Actual T class temperature determined by
design
Mineral insulated Inconel heating cables
can operate to a maximum sheath
temperature of 600 C. MI Inconel cables
offer the industrial heat tracing market
excellent corrosive properties against a
range of harsh environments with a high
temperature capability.
Usage
Cables are typically used on bitumen plants, gas plants, oil refineries, reactors and
vessels, sodium loops and a variety of other heat tracing applications where
temperature, efficiency, durability and cable safety is paramount.
MI cable features
 Corrosion resistance
 High performance output
 High resistance to mechanical abuse
 Safety and fire resistance

Follow steps below to obtain sheath temperature guidelines from the graph for ordinary area
applications.
Step 1: By design, identify cable reference to be used and calculate watts/meter
rating of cable/element e.g. HIQ1M1000, 100watt/m.
Step 2: Refer to rating factor table and multiply watts/meter rating of cable/element
by rating factor to obtain adjusted watts/meter value. (100W/m x 0.840 = 84W/m)
Step 3: Using adjusted value, enter graph on watts/meter axis and obtain cable
sheath temperature for application maintain temperature. Cable sheath temperature
= 540⁰C for 400⁰C maintain- see graph.
