The heating tape is wound around the equipment that needs to be heated, and the outside needs to be covered with an insulation layer. There are many common insulation materials, such as rubber, PEF, glass wool, rock wool, etc., which can be selected according to specific conditions. The thermal insulation layer can reduce the heat loss of the heat in the heating zone under the cold and low temperature heating environment, so that the heat is supplied in a concentrated manner. Just like wearing a cotton coat, it stores heat and fulfills the purpose of use. At the same time, external insulation can play a role in isolation and protection. It also slows down energy consumption and increases its service life.
After the heating belt construction test, the insulation layer should be installed, and the following points should be paid attention to during the installation process:
1. The material, thickness and specifications of the used insulation layer meet the requirements of the design drawing.
2. The insulation materials should be kept dry during construction.
3. A waterproof cover should be added outside the insulation layer.
4. Avoid damaging the heating tape during the construction of the insulation layer.
5. After the insulation layer is constructed, the electric heating belt should be tested for insulation.
6. Put a warning label on the insulation layer and indicate the location of the accessories.
The above are the precautions for installing the insulation layer. In fact, in most cases, the problem is caused by the irregular operation of the installation, so it is very important for the installation, and the standardized installation can be used normally.
