Selection of electric heating type of fire hydrant sprinkler system
Fire hydrant sprinkler system is an important fire prevention and fire extinguishing device. In engineering practice, due to improper handling of the design, construction, maintenance and other reasons, if the fire pipe is blocked or damaged by freezing, it will cause more serious damage consequences, we recommend using heating tape to solve.

Design principles of electric heating and thermal insulation of the metro
The normal operation of the subway is inseparable from the safety of the fire pipeline. In the cold winter, the fire-fighting pipeline without antifreeze measures often freezes. Great hidden danger. Currently, drainage pipes and fire-fighting pipes at subway stations and tunnel entrances use electric heating to prevent freezing and keep warm.

Fire and domestic water supply pipes of ventilation shafts, entrances and exits, ends of sections and entrance and exit sections of the railway station are extremely vulnerable to freezing, while traditional constant power heating cables generate constant heat and cannot be crossed. Not suitable for shutdown, power will increase after shutdown, and there are certain shortcomings in cable burning and energy saving. After research, a self-regulating electrical insulation system was finally selected to protect subway pipelines from freezing.

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.
