Pipeline electric heat tracing system

Product Description
Note: In addition to MI cable and constant power cable are for explosion-proof type. When we choosing self-regulating electric heating cables, we must be based on whether the site is explosion-proof, corrosion, etc., to select the corresponding occasion.
In cold regions, the different medium has different temperature maintenance requirements. even if the temperatures are the same, according to the differences of medium’s viscosity and flow rate, there is a difference in model selection and electric heat tracing should be used in the type ofof its corresponding pipelines. 
1. low temperature series self-regulating electric heating cables is a special type of electric heating cables for pipe antifreeze, it can be maintained at 0-50 ℃, This cable is suitable for medium for water, gas and other antifreeze, specific are, including condensate water; deoxygenized water; desalted water; softened water; circulating water; fresh water and so on.( condensate water of steam measurement lead) There are some low concentration of alkalis, acids and other mediums, if the steam pipeline heat tracing needs to use the MI heating cable,( we have to consider the high temperature of outer steam)
2. middle temperature series can be maintained at 0-90℃, this cable is suitable for light oil mediums: such as gasoline, kerosene, diesel or liquid hydrocarbon, etc., the difficulty of heat tracing is not high, because oil is often mixed with water. Besides, in general industrial applications, parallel constant watt power heat tracing is more widely used (the general specification can be maintained at 0-150℃) it can control temperature accurately. And we will chose series resistance heating cable if the pipeline is longer.
3. MI cable( can be maintained at 0-600℃), the constant watt power heating cable is suitable for type of heavy oil mediums: such as heavy oil; residual oil; wax oil; fuel oil; slurry oil; bitumen and so on. And the temperature of these mediums must be maintained at 60℃-80℃, vacuum constituents should be maintained at 30℃-50℃.
