Electric heating can effectively solve the problem of plugging pipelines at coke plants.
Winter anti-freeze and anti-condensation work at coke plants is the main means of ensuring safe production. To strictly prevent all freezing accidents, strengthen the collection, delivery, use and management of items that are easy to freeze and condense and prevent them in advance according to the basic method. It is envisaged that inspections should be carried out carefully, And the freezing blocking problem must be solved reasonably in order to achieve the goal of ensuring safe production.

Electric heating technology is easy to install, accurate to operate, energy-saving and maintenance-free, and its cost is only 1/10-1/16 of the cost of conventional steam heating. The Shougang resettlement project in my country and the Jinan Iron and Steel Coke Plant used electric heating cables and were successful.
Electric heating is an efficient, clean, and environmentally friendly heating method that is characterized by only consuming electricity during heating and effectively reducing the phenomena of leaks, pops, drips, and leaks that are often caused by steam electric heating. Which can significantly improve the production of enterprises. environment.
Electric heating can achieve zero emissions and really plays a role in saving energy and reducing emissions. The material used is a polymer material with memory function that can accurately control the temperature. When the heating reaches the required temperature, the heating stops, when the heating is not needed, it can be stopped at any time, avoiding the energy consumption caused by steam heating, only to prevent the pipeline from freezing when the pipeline is not needed. To be heated.
Significant cost savings can be achieved through the use of electric heating. For example, if an electric heating is used at a steel mill, the estimated energy consumption of pipelines per hour is 0.049 yuan/m; when using steam heating, the energy consumption of pipelines per hour is 0.48 yuan/m; two-1: 9.8, electric heating Operating costs are much lower than with steam heating.
Electric heating is not only suitable for various situations of heating steam, but also for pipelines with a heat-sensitive environment. It can effectively control the temperature and prevent overheating of the pipeline. Suitable for pipelines or equipment that are scattered or remote from the gas supply point and equipment of irregular shape.
The choice of coolant should be selected according to material properties, indicator requirements, design complexity, operating costs, etc. D., and the construction should be carried out in accordance with the specifications to avoid new problems in achieving the goal. Antifreeze and anticondensation.

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.
