Electric heating is the best choice for fire insulation of pipelines at oil depots
Low temperature self-regulating electric heating cable and self-limiting temperature electric heating cable, the heating cable is in the form of a strip with a width of more than 11mm, which can cling to the surface of the pipe and use electrical energy for heating. The environment in the spray pipe to keep warm plays the role of keeping heat and antifreeze in a short time. In addition, the electric heating belt has the advantages of simple installation, easy maintenance, 24-hour maintenance, high automation, low operation and maintenance costs, etc. D., has good economic and social advantages, and is very suitable for large-scale promotion.

Currently, treatment measures for freezing drainage ditches mainly include increasing the length of thermal insulation ditches, adding frost-resistant drainage holes, and additional electric heating of the ditches. If the tunnel has already been put into operation, then on the basis of a comprehensive accounting of such factors as technical complexity, construction cost and operation safety, a decision is made to use the electric heating scheme of the ditch for processing.

Electric heating system for extinguishing fire in the area of the oil tank
As soon as a fire and explosion occurs at the oil depot, this will lead to serious human casualties, so the design of fire protection for the tank farm has become a top priority. In order to ensure the reliable use of the fire protection system in winter and realize the insulation and antifreeze of the fire protection pipeline, the fire protection pipeline in the oil depot should take insulation measures.

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.
