Highway tunnels are important transportation facilities, and their safety, reliability and operating efficiency are often directly related to the smooth travel of people and economic development.
In tunnel construction, the application of heating cable insulation in highway tunnel pipelines is very common, such as water supply and drainage, ventilation and other pipeline systems will be arranged in the tunnel.
However, the temperature in the tunnel is relatively low and the humidity is high. Pipes in this environment for a long time are prone to condensation, freezing and cracking, which brings inconvenience to the normal operation of the tunnel.
Therefore, in the design process of the pipeline, in addition to ensuring the smoothness and reliability of the pipeline, it is also necessary to consider how to keep warm and prevent condensation and freezing.
Electric heating is a pipeline insulation method that is suitable for heating various media and can achieve automatic constant temperature by controlling the current.
The use of electric heating tape can be hung on the outer surface of the pipeline or in the outer sleeve, which can not only play a heat preservation effect, but also eliminate condensation on the pipe wall, and improve the safety and reliability of the pipeline.
For the pipeline system in the highway tunnel, it is necessary to pay attention to insulation and prevent condensation and freezing during the design and construction process.
As a relatively efficient insulation method, electric heating tape has been well used in the insulation of highway tunnel pipes, providing people with safer and faster travel services.
