Diagram of electric heating sprinkler fire extinguishing system
The water in fire sprinkler pipes is static and is more likely to freeze in winter than in other types of water pipes. Although the time when the outside temperature drops below the freezing point in winter is relatively short, there is also a possibility that the static fluid in the pipeline may freeze. Therefore, the fire extinguishing system must be isolated. And electric heating is a very good insulation measure.

Fire sprinkler system is a widely used stationary fire fighting equipment. Since the initial stage of the fire is the best time to extinguish the fire, the fire sprinkler nozzles must be maintained in normal operation for 24 hours.
However, the water in the fire sprinkler pipe stands still and is more likely to freeze in winter than other types of water pipes. Northeast China, North China and Northwest China are to take thermal insulation measures for spraying in winter. Even in East China and Southwest China, where the temperature is relatively high, although the time when the outdoor temperature in winter is below the freezing point is relatively short., there are still liquids in the pipeline that can also freeze. Therefore, the sprinkler fire extinguishing systems in East and Southwest China also need to preserve heat. And electric heating is a very good insulation measure.
The electric heating cable uses the method of converting electrical energy into thermal energy to maintain the temperature required for the pipeline, which ensures safety, environmental protection and energy saving. Generally speaking, until the sprinkler system freezes, with the exception of some northern areas, the general fire sprinkler system can meet the heat preservation requirements by using self-regulating electric heating cables.
The above is only the electric heating circuit of the fire sprinkler system. You can find out from the electric heating manufacturer how the sprinkler system coils the electric heating.
Of course, the self-control low temperature electric heating belt is not only used for fire protection, but also widely used in civil solar energy, geothermal heating, fire protection, petroleum, chemical, steel, electric power, environmental protection, etc. D. Pipelines and tanks of industrial enterprises., anticoagulants, antifreezes.

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.
