Electric heating system for underground pipeline
Electric heating is widely used as effective pipe insulation and antifreeze. Its working principle is to dissipate a certain amount of heat through the heat transfer medium and make up for the losses of the heated pipe through direct or indirect heat exchange to meet normal operating requirements for temperature rise, heat preservation or antifreeze.

Electric heating system thermal insulation port petrochemical pipeline
In the petrochemical industry in the north, when crude oil, diesel fuel, bitumen oil and other raw materials are transported through trunk pipelines, the pipeline system must be treated with thermal insulation and heating to ensure the smooth transportation of petroleum products. Now take Liaoning Yingkou Port as an example to briefly introduce the application of our electric heating products for pipeline insulation.

Electric heating system of gutts from snow
It is well known that engineers of roof drainage systems collect rain and melt water and preserve it in orderly drainage channels. In parts of the northern part of my country, when the weather is cold, rainy and snowy, because of the large temperature difference between day and night, the sun is enough at noon, the snow on the roof begins to melt and the snow slowly drains. Flows into the roof chute The remains of melted ice and snow will gradually freeze, forming an ice dam in the chute, making it difficult to rank the subsequent melted ice and snow. Chute.

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.
