Application Example of Heating Cable for Ramp Snowmelt on Coal Mine Road
On the long descent of a mountain road in a mining area, the icing phenomenon has existed for a long time. If a snow melting agent is often used, it damages the road structure and pollutes nearby soil, vegetation and other ecological environments. Therefore, it is necessary to choose a new method of melting snow and ice with long-term effect and without side effects.

On the choice of configuration of electric heating of oil pipelines in ports
Due to the long distance between the port terminal and the tank farm at the rear, the pipeline is an artery connecting the vessel and the shore. According to the characteristics of crude oil, most oil pipelines in northern ports need heat preservation and heating to prevent clogging of pipelines.

Example of use of electric heating in snow melting trough canopy
To ensure the safety of high-speed rail stations in high-altitude areas, snow melting in gutts is an important safety issue that cannot be ignored. If the snow is not melted and drained in time, it will freeze easily and cause the canopy trough to overflow to form an inverted ice cone that poses a hazard to passing passengers and vehicles. Therefore, it is considered to use a form of auxiliary heating to melt snow in a certain area to eliminate the hidden danger of accidents.

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.
