Electric heat tracing for asphalt pipelines
Thread Content
Have any of you who work in the marine industry come into contact with electric heat tracing? For asphalt pipelines with a high softening point, steam heating does not provide very good results; I would like to know about electric heating – is its cost high? What about the daily maintenance and performance?
Electric heat tracing has not been used; steam jacket heat tracing can be employed, and it works very well!
I’ve used electric heat tracing here; it worked well at first, but maintenance became problematic later on, mainly due to the tendency for short circuits to occur
Electric heating tubes break easily and are difficult to maintain
Using jacketed heat transfer oil for heating can be considered. We are prepared to adopt it.
Electric tracing is rarely used in refineries; if steam tracing is not effective, jacketed tracing could be considered as an alternative
We are currently using steam jacket heating, but the temperature is a bit low, around 170°C. The softening point of asphalt is relatively high, at around 100°C; therefore, the heating effect is not very good. If we were to switch to medium-pressure steam heating, it would be necessary to change the grade and material of the pipes, which is quite complicated. That’s why we are considering electric heating instead
We are building a project involving 1.4 million tons of leaching, using the AXENS process, with heat tracing via heat transfer oil jackets. For inquiries, contact: qq1034531939
Heat transfer oil works well too; the key question is where does the heat in heat transfer oil come from? Is it heated by a separate heat transfer oil furnace or by a heat exchanger?
Asphalt is generally heated using heat transfer oil, through a separate heat transfer oil system. If your electricity costs are low, electric heating can also be used, but the cost will not be much lower. You will need to remove the existing insulation from the pipelines, install electric heating elements, and then add insulation again.
