Purchase order for Xiongan International Convention Center's snow melting gutter system
In winter, due to cold air, the temperature in the New Shungang District can drop below-10 ° C, and the accumulation of snow exceeds 10 centimeters. If snow falls on the roof of the Xiong'an International Convention Center, it will not only affect the appearance but also pose a huge security threat. Therefore, snow and ice must be melted. After many comparisons, our heating cable has become a powerful tool for melting snow and ice on the facade of the Xiongan International Conference Center.

Constructive characteristics of the electric heating system in cold conditions in the Mohair area
Mohe has a special geographical location and an extremely cold environment, where the lowest temperature reaches-50 ° C. Consequently, pipelines in extremely cold conditions must rely on electric heating systems to maintain pipeline temperatures in situ to ensure safe production.

Composition of insulation of pipes and antifreeze system of electric heating
The purpose of pipeline insulation and antifreeze is to make up for the heat loss caused by the temperature difference inside and outside the pipeline shell. To achieve the goal of protecting the pipeline from freezing and preserving heat, it is only necessary to ensure the heat loss of the pipeline, maintain the thermal balance of the fluid in the pipeline and keep its temperature virtually unchanged.

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.
