Electric heating systems are used in petroleum, chemical, electric power and other industries, and are widely used in pipeline and tank insulation.
The actual electric heat tracing will encounter some faults when using, and we will analyze the faults of unstable heating and uneven heating of the electric heating system.
Problem 1: The electric heating heating insulation is broken, the electric heating system is flooded and damp, at this time the electric heating system works at low temperatures, and the use is easy to lead to uneven heating, and long-term use will also lead to short circuit phenomenon.
Solution: Repair or replace the broken electric heat trace
Problem 2: The electrical heat trace PTC resistance matrix elements are unevenly arranged or the resistance value is damaged, that is, the performance of the electric trace itself changes.
Solution: Replace the electric heat trace
Problem 3: Exceeding the length of use of the electric heat trace itself
Solution: Please use according to the exact design requirements, if the length of the heat trace exceeds the length of the cable itself, according to the standard length of use, provide a power point in the middle, and install the power junction box.

Problem 4: The accessory comes off or the electric trace is cut off
Overhaul accessories, repair electric heat traces.
Problem 5: Power supply circuit or voltage problems, such as the supply voltage is zero or low
Solution: To overhaul the power supply system, you can set up an independent electric heating system power supply point to ensure sufficient power supply voltage.
Problem 6: Electric heat tracing insulation layer, when the insulation layer is too thin, the heat storage performance is affected, and the heating effect is not good.
Solution: replace or thicken the insulation layer;
