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.

Xiongan International Convention Center, as an important meeting place to guarantee a new area in the next 5-10 years, is an important part of the Xiongan International Hotel project. The Xiongan International Hotel project includes an international conference center, an international hotel and thirteen buildings for VIP receptions. The total investment is about 4.3 billion yuan!

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.

The external sheath of the special snow melting cable we offer is made of imported ptfe, which has obvious characteristics such as extreme frost resistance (-40 °C), heat resistance (65 °C) and UV resistance. The snow melting cable within ten years will not exceed 10%.

The snow melting system of this project uses self-heating cables that can adjust the output load based on facility conditions to maximize system energy saving.

1. Determine the number of heating wires according to the width of the gutter.

2. The snow cable is laid in the center of the gutter, and the heating cable is fixed on the surface of the gutter with a special fixing bracket, and the bracket is applied to the surface of the gutter with special glue.

3. Power distribution cables are laid along the network frame on the bottom surface of the roof, and the roof is broken from the side wall of the chute to exit into the outer chute, the perforation is sealed with a sealant.

4. Each junction box is equipped with a set of temperature control devices, and the temperature and humidity sensor is placed in the outer chute closest to the junction box.

The components and accessories of the snow melting system of this project mainly include: terminal box, passageway junction box and power junction box. The end box is used to seal the end of the heating cable, the pass-through connecting box is used to connect the heating cable itself, and the power connecting box is used to connect the heating cable and the power cable.

After processing the joints in the terminal box and the passageway junction box, since they are practically installed on the roof, all of them must be filled with insulating and waterproof silicone 704 to prevent water vapor and cause leaks, short circuits and other phenomena.

The power junction box is fixed on the outside of the trough (on the side of the covered horse track) via an externally treated bracket when mounted The bracket and iron plate are fixed by dovetail nails, and the power junction box and bracket are fixed by stainless steel cable ties.

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.
