Caustic soda is one of the important raw materials in chemical production. At present, the main production of caustic soda, flake caustic soda and granular caustic soda are the two main types of products, especially granular caustic soda is high-quality alkali. It is also used in high-tech products such as microcomputer motherboards. In the process of production of granular soda, it is necessary to use high-temperature electric heating.

Design features of electric heating system of fire extinguishing pipeline
Conventional heat preservation can only delay the freezing time of pipelines, but cannot fundamentally solve the problem of antifreeze. A heating line must be laid between the pipeline and the insulation layer to compensate for the heat loss of the pipeline, keep its temperature within the normal operating range and actually achieve the antifreeze effect of the pipeline.

Optimization diagram of electric heating cable for coal methane head system
Since the electric heating cable in the coal seam methane deposit is used to heat and insulate the outer wellhead pipeline of the coal seam methane deposit, it is greatly affected by the outside air temperature, that is, the temperature difference between day and night. Compared with constant power electric heating cables, warm electric heating cables are more suitable for use in such working conditions.

In the process of production, storage and transportation of liquid chemical products, the traditional method of heat preservation-steam electric heating-was previously used. However, the steam temperature is much higher than the temperature range that the material must maintain, so improper temperature adjustment will cause local overheating of the material. In addition, steam heating has disadvantages such as high cost of use and difficulty of maintenance.

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.
