Product Specification

Heat Trace Mineral Insulated Heating Cable for Vessels and Tanks is an integrated technical solutions for the use on heat trace of vessels and tanks. The MI cable heat tracing can ensure the tanks and vessels maintaining products at a targeted temperature. 

There are three ways to lose heat from a tank or vessel.

First of all, heat flows from the contained medium may be transferred through the walls, floor and roof and fittings of the tank or vessel to the outside ambient  by thermal conduction. 

Second, convection effects

Third, radiation. All bodies radiate heat if they are hotter than their surroundings. 

Heat Trace Mineral Insulated Heating Cable for Vessels and Tanks can meet the needs of high temperature condition and heat tracing of long-distance transportation pipeline. The maximum withstand temperature of the copper sheathed heating cable (MICU) provided by MICH can reach up to 250℃. Conductor resistance value ranges from 1.7-2000Ω/km. For the occasion of anti-corrosion or buried application, high density polyethylene (HDPE) outer sheath ( cable known as MIHC) is needed to be added. MIHC’s withstanding maximum temperature can be up to 90℃. Mineral insulated heating cable possesses excellent mechanical strength. The heating cable of series resistance provided by MICH can meet the requirements of different power levels.
