Causes of electric heating failure

As an effective pipe insulation and anti-freeze solution, electric heating has been widely used in many fields. However, you may encounter some problems during use, the most common of which is electric heat tracing failure. Let’s discuss the causes of electric heating failures.

The electric heating system mainly consists of electric heating tape, power junction box and temperature controller. Electric heating failure can occur in any component, but the most common problems focus on the electric heating tape and power junction box. Here are a few possible causes of electrical heat tracing failure:

1. Resistance wire failure: The resistance wire of the electric heating tape is the core part. If it fails, the electric heating tape will not work properly. Resistance wire failure is usually caused by prolonged use, improper installation or aging of the equipment.

2. Power supply junction box failure: The power supply junction box is an important part of the electric heating system. If the power junction box fails, the electrical heating tape will not function properly. Power junction box failure is usually caused by poor waterproof performance, irregular installation or aging equipment.

3. Temperature controller failure: The temperature controller is an important part of the electric heating system. If the temperature controller fails, the electric heating tape will not be able to generate heat according to actual needs, resulting in poor insulation or insufficient anti-freeze effect. Temperature controller failure is usually caused by excessive use, aging of the equipment, or improper adjustment.

4. Improper installation: Improper installation of electric heating tape may also lead to failure. For example, electrical heating tape may be stretched or twisted, which may cause the resistance wire to break or the insulation to become damaged. In addition, if the electrical heating tape has poor contact with the pipe, it may prevent heat from being transferred to the pipe effectively.

5. Harsh usage environment: In some usage environments, the electric heating tape may be corroded, polluted or mechanically damaged, leading to failure. For example, in environments such as the chemical industry or offshore platforms, electric heating tape may be corroded by chemicals or corroded by seawater.

6. Improper maintenance: Regular maintenance and upkeep of electric heating tapes are important factors to ensure their normal operation. Failure to clean up the dust or check the wiring terminals in time may lead to problems such as poor contact or short circuit.

7. Equipment aging: Long-term use of electric heating tape may cause equipment aging. Failure to replace in time may result in malfunction.

To sum up, there are many reasons for electric heating failure, including quality problems of the equipment itself, improper operation during installation and use, and environmental factors. In order to prevent these problems from occurring, users need to take a series of protective measures. Only in this way can the normal operation of the electric heating system be guaranteed and its service life extended.
