How To Choose Electric Heating Cable For Oil Tank Zone Insulation
Although the source of steam heating is convenient, and the latent heat is great, its quantity is large, the technique is complex, and temperature control is difficult. Simply because it can avoid the above disadvantages, it is widely used.

Electric heating is to use the heat emitted by the electric heating belt itself to compensate and maintain the heat lost in the oil storage tank in order to maintain the most reasonable process temperature of the flowing medium. The electric heating is evenly laid on the surface of the tank. It is different from the high-concentration heating device in a small area. The electric heating has a low temperature gradient and strong thermal stability. The power is significantly lower than other electric heating decoration, which is suitable for long-term use.
Oil depot also refers to special equipment used for oil storage, due to the specifics of oil used for storage in the corresponding oil depot. The oil depot is a link for coordinating crude oil production, refining crude oil, supplying and transporting refined oil. Crude oil is a mixture of various liquid hydrocarbons such as alkanes, cycloalkanes, aromatic hydrocarbons and olefins. The main components are carbon and hydrogen, accounting for 83-87% and 11-14%, respectively, a small amount of sulfur, oxygen and nitrogen are also present, as well as trace amounts of phosphorus, arsenic, potassium, sodium, calcium, magnesium, nickel, Iron, vanadium and other elements. The specific gravity is 0.78-0.97, the molecular weight is 280-300, and the freezing temperature is-50-24 ℃. In order to prevent the oil product temperature from falling during the transportation process, which will affect the normal transportation, it is necessary to use electric heating to solve the freezing problem of the oil depot process pipeline.
Traditional electric heating mainly uses steam, hot water or heat transfer oil as heat transfer fluid, and then provides heat through jacketed pipes, coils, etc. D. However, each of these methods has its advantages and disadvantages. Although the source of steam heating is convenient, and the latent heat is great, its quantity is large, the technique is complex, and temperature control is difficult. Therefore, electric heating appeared. Simply because it can avoid the above disadvantages, it is widely used.
Generally speaking, both self-regulating electric heating cables and series-parallel constant power electric heating cables are used, but sequential constant power is typically used for long piping with or without multiple branches, and parallel constant power and self-regulating temperature are more suitable. For parallel chains More heating pipes.

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.
