Application of mineral insulated heating cable in melamine production
For the pipe and valve, where the liquid melamine flowing out of the melamine reactor and the gas produced by the reaction flow into the cooling column, strict measures must be taken to heat and keep heat. It is not easy to control the temperature of the steam heater, but the heating cable can ensure that the environment temperature meets the production requirements.

The application of mineral insulated heating cable in the production of melamine
Electric heating is to use electric heat to replenish the heat lost by the heated object in the production process, so that the temperature of the medium can be maintained within a certain range. As one of the key national promotion projects, electric heating technology is widely used in pipelines, valves,
The production process of melamine is relatively complex, and there are strict temperature requirements for melamine in the reaction and transportation process (about 380 degrees Celsius). If the temperature is too high, it can lead to contamination of the reactor tube beam; Too low temperature, melamine resulting from the reaction can crystallize There is a danger of clogging the pipe Therefore, it is necessary to take strict measures to heat and preserve heat for the pipe and valve, where liquid melamine flows out of the melamine reactor and the gas produced by the reaction enters the quenching column. It is not easy to control the temperature of the steam heater, but the heating cable can ensure that the environment temperature meets the production requirements.
The melamine device of the chemical company in Henan uses the heating cables mi. The material of the metal shell is alloy 825. When the current passes through the heating core of the consistent resistance of the cable, heat is released. The heating is uniform. And the cable length is different, the maximum heating temperature is 600 ℃.
Mineral insulated heating cable has the characteristics of high temperature resistance, corrosion resistance, fire protection, explosion safety, anti-aging, high mechanical strength, high maintenance temperature, high power output, uniform heating throughout the length, long service life, ease of installation (small diameter)., Can be bent into any shape), etc. D.

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.
