Electric heating is widely used in the metallurgical sodium industry Electric heating belts are usually used for heating and heat preservation of storage tanks of industrial equipment, pipes, tanks and other containers within 130 ° C. However, there are very few technical applications for heating and heat preservation of storage tanks for working equipment, pipes, tanks and other containers above 130 °C, and armored heating cables can be used.
According to the requirements of the new sodium metal process, the estimated temperature of the pipeline surface is not lower than 120 °C, especially when the sodium medium is flowing in the pipeline, the temperature cannot be reduced, otherwise the sodium will stick and solidify. Block the pipeline, which poses a security threat. Our armored electric heating system is great for heating and heat preservation of industrial equipment, pipes, tanks and other tanks in the temperature range from 130 °C to 600 °C service life High temperature resistance, fire resistance, high mechanical strength, corrosion resistance, explosion safety, easy control.
Armored electric heating is commonly understood as mineral insulated heating cables. This heating cable consists of a metal core (heater body), the core is tightly surrounded by mineral magnesium oxide (insulation layer) and a metal tube (usually made of copper, steel or stainless steel, 316L alloy, 825, etc. E.). If desired, the layer of the anticorrosive outer shell of polyperfluoroethylene-propylene can be squeezed out of the metal shell.
Armored electric heating is suitable for freezing protection in industry or construction, as well as for heat preservation and temperature improvement in process environments. Especially for pipelines that require high power output or must withstand high temperature steam purging and work at high temperature for a long time, in environments that require anti-corrosion and explosion safety, the mineral insulated heating cables of the MISS electric heating system can show excellent performance.
Armored electric heating products are usually manufactured in the factory and assembled from complete components. When delivered, the fuel part of the armored electric heating is connected to the cold end armored wire section through a cold and hot joint, and the lead wire is pulled out through a cold end joint and equipped with tip bolts that can be directly connected to the junction box. The cold end armored wire is an unheated armored electric heating made of pure nickel or pure copper and configured according to the current of each armored heating cable. The length of the cold end reinforced wire is usually 0.5-2.5 m, and it connects to the reinforced heating cable through a sealed connector.

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.
