Advantages of electric heating in the heating system of pipelines
Electric heating is often used in petrochemical plants to maintain or compensate for heat losses in pipelines during production operations and shutdowns. Usually hot water, steam and electric heating are used as a coolant. However, due to the large number of daily maintenance of steam and water heating, problems such as the inability to maintain a high temperature and control the required temperature are gradually replaced by electric heating.

Most of the petrochemical production equipment is generally completely open, and the flow is organized in a straight line, so it is very important to prevent freezing during production in winter. In addition, the process pipelines of these devices have different and complex production conditions due to different environments. Therefore, the reasonable choice of coolant and the determination of the heating method should depend on the conditions of the production process.
Electric heating is often used in petrochemical plants to maintain or make up for heat losses in pipelines during production operations and shutdowns. Usually hot water, steam and electric heating are used as a coolant. However, due to the large volume of daily maintenance of steam and hot water heating systems, problems such as the inability to maintain a high temperature and control the required temperature are gradually being replaced by electric heating.
Electric heating has been widely used as an effective heat preservation and freezing protection solution for pipelines, tanks and equipment. Electric heating has a low temperature gradient and a long time of thermal stability, which is suitable for long-term use, and the heat (electricity) required by it is significantly lower than that of electric heating. Electric heating has the advantages of high thermal efficiency, energy saving, simple design, convenient design and installation, no pollution, long service life, remote control and automatic control, etc. D. It is widely used in industrial production such as fire protection, petroleum, chemical industry, steel, electric power and environmental protection.
The working principle of the electric heating system is to compensate for the heat loss caused by the temperature difference inside and outside the pipeline and the equipment body to achieve the purpose of freezing protection and heat preservation of the pipeline or equipment. Necessary to ensure heat loss in the pipeline or equipment and to maintain the thermal balance of the fluid in the pipeline or equipment, the temperature can be kept basically constant.
While the benefits of electric heating are clear, the decision on what type of heating to use in the project should be made according to the characteristics of the owner and the device. Wonderful achievements In short, electric heating of the canal, steam heating and hot water heating will be the development direction of the heating system.

Electrical heating installation precautions
Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Which electric heating should be chosen for the main pipeline transport of heavy oil
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.
Which electric heating cable should be considered for a 4 km pipeline
According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
