With increased public awareness of environmental protection, it is becoming more and more important to optimize the design of heating chemical pipelines to achieve energy savings and reduce consumption. As a rule, in the work and production of chemical enterprises, the methods of electric heating of main pipelines are divided into four types: steam, water, heat carrier and electric heating with automatic regulation. According to the heat transfer method, it is divided into internal heating tube, external heating tube, jacket heater, etc. D. Among them, electric heating technology is widely used in the production of various industries, especially in petrochemical enterprises, because it is more convenient to use, does not require an increase in labor costs, and is easy to adjust the temperature.

Unlike an electric heating system, the electrically heated cooling system and the heating system are combined into a single unit, simultaneously providing heat for the linear heat source. Although in practical applications, the compensation and heat required by the system cannot be strictly equal, and there is a certain gap, but the electric heating system has no heat transfer problems, so the heat supply of the pipes is relatively uniform, and the above-mentioned pipes in the steam system will not appear the problem of near and far.

Which chemical pipelines are suitable for electric heating:

The heating pipeline with a strong seasonality should choose an electric heating that can be used or turned off depending on the weather temperature with high flexibility.

Electric heating should be used to heat main pipelines and pipelines without steam heat sources or in remote areas.

Electric heating should be used for heating plastic and non-metal pipes.

Electric heating should be used to heat pipelines of intermittent transport medium.

Electric heating should be used for heating and heat preservation of pipelines requiring strict control of the environment temperature.

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.
