The cooling tower uses water as circulating refrigerant. The cooling consists in using water and air to exchange heat and cold to form steam. The steam evaporates and discharges heat to dissipate heat by evaporation, convective heat exchange and radiative heat exchange to dissipate industrial heat. Or an evaporative cooling device that cools the waste heat generated by the air conditioner to reduce the water temperature.

If the steam in the cooling tower cannot be normally diverted during condensation, (this will) fail the entire cooling tower, and electric heating cables are recommended for this.

The electric heating cable is a freezing protection heating product that is used to insulate liquid pipelines. Conventional cooling pipe in industry can use electric heating cable for insulation and anti-freeze protection.

The working principle of the electric heating cable is to use electrical energy to generate heat. The equipment used for heat preservation is liquid pipes. When the cooling tower uses an electric heating cable to heat and preserve heat, the condensed steam inside it will melt in a short time, which improves the efficiency and acceleration of the cooling towers.

The electric heating cable installed in the cooling tower is generally recommended to install the self-limiting temperature electric heating cable. First of all, in terms of temperature, the temperature range of the self-limiting electric heating cable is sufficient to maintain the operating temperature. Cooling tower water temperature in cold weather The flow preservation will not freeze and block the pipeline, and its “ptc” function can be used with appropriate explosion-proof temperature controller to achieve accurate temperature control and automatic operation.

Secondly, in terms of safety, the explosion-proof mesh of the protective layer, equipped with a self-limiting temperature heating cable, has the advantages of anti-static, grounding and spark-safe, and the outer shell of the fluoride material is heat-protected. Resistant, these advantages include corrosion resistance, water resistance and chemical resistance.
Finally, in terms of installation, the self-limiting temperature heating cable is flexible, small in size, easy to install and easy to lay on the surface of the pipeline. The complexity of the installation is reduced.

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.
