There is a lot of traffic in shopping malls, if there is no ventilation system in the mall, people cannot breathe fresh air.
However, for indoor rollers, the indoor temperature should be kept below 15 °C, the ice surface temperature should be kept at minus 5-6 °C, the ice thickness should be at least 3-5 cm, and the relative humidity of the water vapor on the roller should be low. A stream of water vapor through an air capillary can easily produce face cream, and when it reaches the surface of the lake, it forms icy white spots that are unlikely to cause skaters to box or die, adding many unsafe and adverse factors. In addition, if raindrops do not fall on the heads of the audience, it will affect the mood of the people watching the game. In this way, in order for an outdoor roller to create a safe, reliable, scientific and standardized entertainment environment, electric heating can be used to prevent water vapor circulation pipes from freezing in an open roller.
Generally speaking, the electric heating cable for roller piping can be selected low temperature self-regulating electric heating cable. The self-limiting temperature electric heating cable does not need a temperature controller and can automatically control and adjust the temperature, so that the accompanying pipe can maintain a constant temperature. Therefore, it is relatively more convenient than the constant power electric heating cable, and it is more cost-effective.
The heating cable is evenly wound along the pipeline and other objects, and the temperature controller of the heating cable is used to control the temperature of the outer surface of the pipe. When the temperature at the detection point is below the set value, the temperature controller is turned on and the electric heating system starts to work to maintain the temperature of the pipeline equipment. When the temperature sensor detects that the temperature of the pipeline is higher than the set temperature, the thermostat disables the power supply so that the electric heating system can operate in the most economical and reasonable condition and meet the design requirements for the fire temperature. -Fight against pipeline insulation.

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.
