Electric heating cable is used for catalyst pipeline antifreeze and heat preservation

In many fields such as chemical production, the normal operation of catalyst pipelines is crucial. In cold environments, antifreeze and heat preservation of pipelines have become a problem that must be solved. The application of electric heating technology provides an efficient solution for the antifreeze and heat preservation of catalyst pipelines.

Hazards of pipeline freezing

In winter, low temperatures may cause the medium in the catalyst pipeline to condense or freeze. Once freezing occurs, the fluid in the pipeline cannot flow normally, which will seriously interfere with the entire production process. For catalyst pipelines, freezing may cause the catalyst to fail to reach the reaction area in time, thereby affecting the normal progress of the chemical reaction, reducing production efficiency, and even causing serious consequences such as substandard product quality.

Working principle of electric heating tape

The principle of electric heating tape for catalyst pipeline antifreeze and heat preservation is to wrap electric heating cable on the pipeline and then wrap the cable with insulation layer. Industrial self-limiting temperature electric heating tape has special performance. It can automatically adjust the output power according to the temperature of the heating system. This means that when the pipeline temperature is low, the electric heating tape will increase the power output and quickly increase the pipeline temperature; and when the pipeline temperature reaches a certain value, the electric heating tape will automatically reduce the power to prevent burning due to self-heating, thereby achieving constant temperature heating.

Advantages of using electric heating cables on catalyst pipelines

1. Efficient heat preservation

Electric heating cables can flexibly adjust the heat output according to the actual temperature requirements of the pipeline, ensuring that the catalyst pipeline is always in the appropriate temperature range and effectively preventing freezing and blockage. This is critical to maintaining the activity of the catalyst and the normal flow of materials in the pipeline.

2. Easy installation and maintenance

The installation of electric heating cables is relatively simple. When installing, just keep it close to the heated body (catalyst pipeline) to improve the thermal efficiency. If the heated body is a non-metallic body, aluminum adhesive tape can also be used to increase the contact heat transfer area and fix it with nylon cable ties. Its maintenance is also relatively simple, with low operating and maintenance costs, all-day service, and high automation level. For chemical companies, it can reduce the investment in manpower and material costs.

3. Safe and reliable

Electric heating cables are safe and reliable. When using them, as long as they are operated in accordance with relevant specifications, such as waterproofing the head and tail end caps, installing leakage protection switches, and working in a dry state, they can ensure safe operation and will not cause safety hazards to the production environment.

Precautions for using electric heating cables

1. Regular annual inspection

Before using them in winter, the electric heating cables should be inspected annually, including insulation and waterproofing tests.

2. Correct installation

It is strictly forbidden to expose the electric heating tape outside the insulation layer, otherwise it will increase energy consumption and reduce service life. At the same time, it is strictly forbidden to mix steam heating and electric heating together, and the insulation layer must not be damaged during installation.

Conclusion

Electric heating tape has many advantages in the antifreeze and insulation of catalyst pipelines. The reasonable application of electric heating tape technology can ensure the normal operation of catalyst pipelines in cold environments, thereby ensuring the smooth progress of the entire industrial production process.
