Especially in the cold north. Not suitable if the amount of steam accompanying the steam is too little or too large. It is best to abandon the heating wire or use another medium heater instead.

For safe production in winter, freezing of the pressure pipes of the instrument is a very troublesome problem. Especially in the cold north of my country, the temperature in winter is low and lasts a long time. The KIP pressure pipeline is often frozen due to the content of the measured environment, resulting in an explosive failure and seriously affecting the safety of production in the winter. The original electric heating system of the instrument sometimes requires an increase in heat dissipation, that is, an increase in thermal energy consumption, that is, the steam consumption is too large, the steam is everywhere in the device, the temperature is low, and the condensed water forms ice cones; when the steam supply is too small, the conductive wire often freezes easily. Which causes the device to fail. For safe production in winter, freezing of the pressure pipes of the instrument is a very troublesome problem.

Heating the instrument pressure pipeline is one of the most difficult tasks for the managers of the instrument. Especially in the cold north. Not suitable if the amount of steam accompanying the steam is too little or too large. It is best to abandon the heating wire or use another medium heater instead.

Electric heating is a heating technology that uses electrical energy as heat, safe and reliable to effectively control the temperature and prevent overheating of the pipeline environment. Due to some problems with steam heating and water heating, electric heating is currently the main method of heating.

A complete electric heating system typically consists of power connectors, electric heating cables, electric heating terminal boxes, three-way junction boxes, double-sided junction boxes, insulation layers, moisture-proof layers and strapping. These devices are mutually complementary and interconnected, if a problem arises in any of the links, this will lead to the failure of the electrical heating system of the PP device.

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.
