The main problems in the field of electric heating design
As an effective solution for electric heating to compensate for heat loss through electric heat exchange, electric heating is mainly used to protect against freezing and preserve heat in pipelines (storage tanks) in the energy sector. As electric heating technology becomes more and more mature, electric heating engineering products are gradually replacing traditional steam and hot water heating products with the advantages of cleanliness, energy saving and ease of management, and have become a key national energy saving project.

As an effective electric heating solution to compensate for heat loss through electric heat exchange, electric heating is mainly used for freezing protection and heat preservation in pipelines (storage tanks) in the power industry. As electric heating technology becomes more and more mature, electric heating engineering products are gradually replacing traditional steam and hot water heating products with the advantages of cleanliness, energy saving and ease of management, and have become a key national energy saving project.
Compared with traditional steam heating systems and hot water heating systems, electric heating engineering systems have the characteristics of good heating effect, simple installation process, energy saving and low maintenance costs. Technical products for electric heating are widely used in the oil, chemical industry, electric power, medicine, mechanical engineering, food, shipbuilding, etc. The main goals of using engineering products for electric heating are winter antifreeze, technological heating and technological heating.
1 Irrational price competition
In recent years, the electric heating industry in my country has begun to experience an oversupply. In order to maintain survival or expand market share, unprecedented market competition has unfolded among electric heating engineering companies. Manufacturers often have fierce competition based on "price wars." Profits of most companies have long remained at very low levels. Time, and the profits of the entire industry have been seriously reduced.
2. Serious product uniformity
Product differentiation refers to the different characteristics and differences of products provided by different manufacturers in the production of similar products. The purpose of the enterprise for the production of differentiated products is to cause special preference among consumers for the products of the enterprise, thereby occupying an advantageous position in the market competition. However, the phenomenon of "imitation" is common in electric heating enterprises in my country. The brand advantage of enterprises is small, the phenomenon of product uniformity is serious, the influence of brands on user purchasing decisions is very limited, and they lack personalized and humanized design.
3 Poor independent innovation capacity
In the development and growth phase of electric heating engineering enterprises in my country, due to the low threshold and short cycle, many enterprises flock to them, emphasizing only large-scale expansion, thus ignoring the investment and construction of enterprises in innovative technology. Some companies lack long-term planning and have become accustomed to mimicking and learning from foreign companies' products when developing new products, resulting in a lack of skills for companies with important technology and relatively few patents for developing electric heating products.
The electric heating engineering enterprises of my country are imperfect in the structure of the technological innovation system: on the one hand, they lack the relevant technical talents and teams, on the other hand, they lack the support of the relevant systems and development processes. Investment in auxiliary resources, such as incentive mechanisms, due to the short-sighted development of enterprises, in order to pursue short-term interests and results, they have abandoned medium-and long-term investment and planning in technology, and the entire electric heating engineering industry lacks an atmosphere of technological innovation.

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.
