In the ventilation shafts of metro stations, station entrances and exits, interval openings, fire extinguishing pipelines without a reporting year and pipelines of production and domestic water supply, electric heating is required to preserve heat. Non-freezing of the pipeline due to active heating and heat preservation.
The composition of the electric heating system of pipelines:
Electric heating insulation control unit. Heating cables, power cables, control cables, temperature sensors, insulation and identification of pipes, etc.
The working principle of electric heating:
But when the pipe temperature is lower than the set temperature, the electric heating system will automatically start the heating circuit to start working, that is, heat the pipe, and the pipe temperature will rise. Temperature, the heating system will automatically stop heating. This electric heating system is done in cycles so that the insulation of the pipeline is always stable, in order to actively heat the pipeline and ensure the normal operation of the pipeline system in the winter. To ensure the effect of electric heating, the temperature sensor is installed at the appropriate place at the lowest point of the pipeline.
Introduction of heating cable system
The heating cable system consists of a thermostat (equipped with a temperature sensor) and a heating cable. The sheath material of the insulation layer selected for the HN heating cable has excellent corrosion resistance, aging resistance, high heat resistance and flexibility, and has a long service life. And passed the demonstration and testing of various reputable organizations, such as the National Center for Wire and Cable Quality Control and Inspection and the National Center for Home Appliances Testing.

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.
