Electric heating system for snow melting on city overpasses
In winter, especially on snow days, snow and ice on the roadway reduce the friction between the tires and the road, making it difficult for the vehicle to maintain direction while driving, and the vehicles involved fail at this time, easily causing traffic accidents. Therefore, how to solve the problem of snow accumulation on the street, now I will present a safe and environmentally friendly method of snow melting, electric snow melting.

With the rapid development of cities, the scale of expressways and urban roads is getting larger and larger, and the total length of roads is increasing. However, traffic congestion and aircraft downtime are becoming more and more frequent. Research and research have shown that good road conditions are the key to normal road conditions an important factor in operation.
In winter, especially on snowy days, however, snow and ice on the roadway reduce the friction between the tires and the road, making it difficult to maintain the direction of the car. Therefore, how to solve the problem of snow accumulation on the street, now I will present a safe and environmentally friendly method of snow melting, electric snow melting.
When electric heating technology is applied to road surfaces, the entire system consists of a heating system and a control system. When the system is installed, it usually needs to be designed according to the composite structure of the road surface and the performance of the heating cable: cut a groove of 2 cm (width) x 2 cm (depth) on the surface of the concrete pavement layer. and then lower the heating cable into the groove (the heating cable is very preheated). Leave excess length, To avoid excessive force on the cable when the road surface is deformed). And fix it in the groove with wire braces and cement nails, and then lay the temperature control cable in the same way. After laying the cable, an asphalt concrete layer is laid. The heating cable and temperature control cable are removed from the edge of the road surface and enter the cable slot through the side ditch of the road surface to connect to the control circuit to control the heater's remote control system. Cable.
After the installation and laying of the snow cable on the overpass is completed, the heating cable can increase the road surface temperature by 1-9.9 ° C to achieve the effect of melting ice and snow. To prevent the snow from melting too quickly after heating and snow water entering other parts of the road causing the road to freeze, the rate of snow melting can be controlled by adjusting the temperature so that the water does not flow into the river. In addition, we can build rainwater ditches or lay rainwater pipes on both sides of the road. Even if the water flows down, the snow water can drain directly into the rainwater ditches.
The TXLP series heating cable can be used not only for most common road materials such as asphalt, cement and floor tiles, but also for snowmelt roads, bridges, roadways, sidewalks, car parks, airport runways, outdoor steps and other outdoor activities. Objects Ice melting and ground heating, snow melting of gutlets, lawn heating, fire protection of tunnel pipelines, etc.

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.
