Problems with electric heat tracing maintenance
Thread Content
May I ask how electric heat tracing is maintained in everyone’s factories? Are there any standards for the aging of electric heat tracing wires?
It can’t be repaired, right? It’s all semiconductors.
Measure the resistance to calculate power; those with poor heating performance need to be replaced
High temperatures can cause an irreversible increase in the resistance of self-regulating heating wires, so they need to be inspected annually. There are also cases where the insulation of the bypass line is too low; I wonder how everyone fixes that
If the insulated heat tracing belt is to be replaced, it must be removed entirely!
