Long-range coal molasses briquettes electric heating pipeline

Compared with the original conventional steam-type heating system, the electric heating system can effectively solve the complex procedures encountered when building long-distance industrial coal briquettes pipelines.

As a new construction technology developed in my country, the molasses pipeline for coal briquettes is basically the installation and commissioning of the electric heating system in the coal briquettes molasses pipeline project. Due to the high viscosity of the most technical honey under normal conditions, it flows poorly through the pipeline. Faced with such a problem, how to effectively solve the normal flow of industrial honey in the pipeline has become a key problem that is difficult to solve. In the coal briquetting project, to prevent the honey from solidifying and the pipeline being blocked, the key technology has become the installation of an electric heating system with a heat preservation device in the project, which effectively solves the problem in the pipeline. The honey phenomenon and the problem of sugar flow have played a good role in promoting the construction of coal briquettes. Compared with the original conventional steam-type heating system, the electric heating system can effectively solve the complex procedures encountered when building long-distance industrial coal briquettes pipelines.

LLHCL ultra-long distance heating cable

The LLHCL ultra-long distance heating cable is a series of high-efficiency resistance heaters that are used for ultra-long length pipelines requiring temperature maintenance or freezing protection. Are used to minimize the number of power points, and a single power point can provide long-distance heating of the line.

Straying LLHCL long cables provide constant power per unit length of the circuit, preventing the voltage from decreasing as the circuit length increases. The solid metal shell increases mechanical strength, protects against external damage during laying and provides excellent fire performance compared to most cables.

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.
