In the field of pipe insulation, heat tracing is a commonly used equipment. It maintains the temperature inside the pipes by providing stable heat energy, thus preventing the pipes from freezing or crystallizing. However, during the use of heat tracing, there are times when pipes are scalded. Below** Some of the key factors that cause heat tracing to burn pipes.
1.The temperature is too high.
The main function of the heat trace is to provide heat energy, but if the temperature is too high, it can cause damage to the pipes. This may be due to improper sizing of the heat tracing, or a malfunction of the controller. When selecting a heat tracing, the appropriate type and power of the heating cable should be determined according to factors such as the material, diameter and ambient temperature of the pipe. In addition, regularly check the function of the controller to ensure that it is working properly to avoid situations where the temperature is too high.
2.Improper installation.
The quality of the installation of a heat trace has a great impact on its performance and safety. If not installed properly, it may lead to uneven contact between the heat trace and the pipe, and local overheating, which can burn the pipe. When installing the heat tracing, it should be ensured that the heat tracing fits snugly to the surface of the pipe, free of voids and wrinkles. In addition, the heat trace should be secured to the pipe using appropriate fixtures to prevent it from moving or slipping.
3.The pipe material is not compatible.
Some pipe materials may be sensitive to the temperature of the heat trace and are susceptible to burns. For example, some plastic and rubber pipes may not be able to withstand the heat of the heat tracing. When choosing a heat trace and pipe, you should make sure that they are compatible to avoid the risk of the pipe being burned. If you are not sure whether the pipe material is compatible, you can consult the manufacturer or professional opinion.
4.Damaged insulation.
Heat traces are usually wrapped with an insulating material to prevent heat loss and protect the pipes. However, if the insulation is damaged, such as abrasion, chipping, or aging, it can cause heat from the heat trace to transfer directly to the pipes, causing burns. Regularly inspect the insulation of the heat trace and replace the damaged part in time to ensure its proper thermal insulation function.
5.Improper use.
Incorrect use may also cause the trace to burn the pipes. For example, excessive bending, stretching, or squeezing of the heat trace can cause damage to the internal wires, which can cause localized overheating. In addition, during the use of the heat tracing, it should be avoided from contact with sharp objects to avoid cutting the insulation. Follow the instructions and operating specifications for the heat trace to ensure proper use and maintenance of the heat tracing.
In conclusion, the factors that cause heat tracing to burn pipes include excessive temperature, improper installation, incompatible pipe materials, damaged insulation, and improper use. In order to avoid these problems, users should strictly follow the relevant specifications and requirements when selecting, installing and using heat tracing. At the same time, the heat tracing is regularly inspected and maintained, and potential problems are found and dealt with in a timely manner to ensure the safety and normal operation of the pipeline.
