The electric heating strip adopts three-layer co extrusion technology, which is characterized by

Users who purchase electric heat tracing tapes hope to choose products with high cost-effectiveness, hoping to use them for a long time and reduce the frequency of replacement as much as possible. However, a certain proportion of electric heat tracing tapes are damaged due to their long operating time, aging, or previous design, installation defects, and construction operations, and batch updates of electric heat tracing tapes that exceed their service life are also normal phenomena.

The electric heating strip adopts a three-layer co extrusion technology, which is characterized in that two metal wires are sequentially coated with a low resistance transition layer, a conductive layer, an insulation inner layer, a metal shielding mesh, and an insulation outer layer. The low resistance transition layer, the conductive layer, and the insulation inner layer are formed by three-layer co extrusion in one go. The application of three-layer co extrusion technology makes the heat tracing structure stable, with low starting current, tightly wrapped without gaps and impurities, edge performance, extended service life, anti-aging, convenient and safe, and extended service life.

In order to reduce the proportion of damage to the electric heating strip caused by external factors, the installation and maintenance of the electric heating strip should pay attention to the following issues:

1. Installation precautions: Whether there is cross winding or too dense spacing (for constant power electric heating strips) in the electric heating strip, causing overheating at the overlapping area and affecting the service life of the electric heating strip. To avoid this issue, the winding spacing and method should be accurately calculated during design, and the most suitable model of electric tracing tape should be selected for installation;

2. Post maintenance personnel should record installation diagrams and relevant test data, and archive them for future maintenance, etc;

3. Attention should be paid to the safety and waterproofing of the entire electric heating system. After the installation of the electric heating strip, a waterproof external insulation layer should be applied to ensure that the electric heating strip works in a dry environment;

4. Regular maintenance should be carried out on the electric heating strip, and key inspections should be carried out on areas that are prone to damage. The bend is generally a place where it is relatively easy to damage the electric heating strip, and testing can start from here. In addition, there are other parts that are more prone to damage to the electric heat tracing belt, such as the discharge point of the tank body, the junction between the upper and lower tank bodies, the liquid level gauge, flanges, valves, and the inlet and outlet parts of the instrument box. These are all areas that need attention and can be used as detection points.
