The electric heating is a uniform heat dissipation over a large area of the volume of the tank. It differs from the electric heating by a highly concentrated load of one point or a small area. The electric heating has a low temperature gradient and a longer thermal stability time, which is suitable for long-term use. The heat (electric power) required by the heater is greater than that of the electric heater.

The constant power electric heating belt is used for electric heating of the wastewater tank.
The electric heating cable uses the heat generated by the heating belt itself to compensate and maintain the heat lost by the oil storage tank to keep the flow to the most acceptable process temperature. The electric heating is evenly laid on the surface of the tank. It differs 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 that of the electric heating. Other electric heating devices. Suitable for long-term use.

Electric heating for filling pipelines in cantilever-continuous beams in railway construction
With the rapid development of railway construction in my country, the construction of adjacent cantilever continuous beams is increasing, and construction must be carried out continuously, and concrete construction in winter is more common. The tension and pouring of cantilever continuous beams are the most important parts of the cantilever continuous beam, and the temperature control of pipelines is especially important in winter construction.

Should a sprinkler fire extinguishing system use electric heating to prevent freezing?
The water in the fire pipe is standing and freezes more easily in winter than in the public water supply. Even in East China with a subtropical monsoon climate, despite the fact that the outdoor temperature in winter for a short period of time is below the freezing point, there is still a possibility that the static fluid in the pipeline may also freeze.

Although one-time investment in an electric heating device is high, operating costs are significantly reduced and the economic benefit is very significant. In terms of use, self-regulating electric heating cables are obviously superior to steam heating in terms of performance, economic benefit, energy saving and environmental protection.

A comprehensive pipe trestle at the Houlunbuir power station site is located outdoors, and the original design uses a steam heating method to prevent cold and freezing. After the heating steam is dizzy in winter, the pipe overpass system in the whole plant has problems such as work, cotton, dripping, leakage, water drainage cannot be recycled, pollution in the plant area, auxiliary steam consumption, easy freezing of pipes, and the impact on the safety and stability of the state system. After converting the steam heating method into electric heating, the integrated heating system of the heating pipe frame of the thermal power plant works in good condition, and the reliability and efficiency of the system have been improved.

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.
