Design solutions of the electric heating system of fire-fighting water supply facilities
The winter temperature in the north is often below 0 ° C, and in mountainous areas even below-30 ° C. When the temperature drops in winter, the phenomenon of freezing and expansion of water in the pipeline can occur, and if there is a fire at this time, the consequences will be catastrophic. Therefore, it is very important to add thermal insulation to fire pipes in winter. Electric heating is more and more recognized in antifreeze and cold insulation because of its advantages.

Electric heating system for snow melting on the spring roof of a large warehouse
After the snow on the roof of the warehouse melts in winter, it will flow into the lower point chute along the sloping roof, so electric heating is mainly laid in the chute so that the snowy mixture does not freeze and drain into the gutter. Drain pipe, manifold, etc. D. Water system, eventually flowing into underground pipes.

Selection of type of electric heating cables for chemical pipelines
In the process of storage and transfer of chemical media, heat loss is inevitable. Many environments with high melting point, high viscosity, easy to hacken and easy to moisture, which will affect the material properties if the temperature cannot reach the required process temperature seriously affect normal production. The electric heating cable uses electric heating to compensate for the heat loss dissipated by the heating pipeline and equipment in the process to ensure that the temperature of the medium meets the specific requirements of the process.

In North China and East China, the problem of non-freezing of open structural pipelines, such as open layers of equipment piping and underground garages, is suffering from production and life. For pipes with a diameter of less than DN40, add the insulation layer in a timely manner. If there is no heat source for heating at low cost at night, the shutdown usually drops from 10 °C to 0 °C within 3 hours, which is very dangerous.

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.
