Electric heat tracingAs an effective anti-freezing and thermal insulation measure for pipelines, it has been widely used in various fields. However, there may be some common problems in the use of the anti-corrosion layer of the electric heat tracing, and these problems may affect the service life and performance of the electric heat tracing if not solved in time. The following will be the common problems and solutions of the electric heat trace anticorrosive layer.
The breakage of the anti-corrosion layer is one of the common problems of the anti-corrosion layer of the electric heat tracing. This may be caused by improper operation during installation, mechanical damage, or external environmental factors, etc. Breakage of the corrosion protection layer can cause the electric heat trace to be exposed to corrosive media, which will accelerate its corrosion rate. The solution is to find and repair the damaged anti-corrosion layer in time, which can be repaired with anti-corrosion paint or tape.
Peeling of the antiseptic layer is also a common problem. This may be due to insufficient adhesion between the corrosion layer and the substrate, or due to temperature changes, vibrations, and other factors. Peeling off the corrosion layer can leave the substrate unprotected and susceptible to corrosion. The solution is to ensure that the surface of the substrate is clean and dry before installation, choose a suitable anti-corrosion coating, and paint it in strict accordance with the construction requirements.
In addition, the aging of the anti-corrosion layer is an unavoidable problem during the use of electric heat tracing. After prolonged exposure to the outside environment, the antiseptic layer will gradually lose its properties and become fragile and brittle. Aging anti-corrosion layers cannot effectively prevent corrosion. The solution is to check the condition of the anti-corrosion layer regularly and replace the aging anti-corrosion layer in time to ensure the protective effect of the electric heat tracing.
The anti-corrosion layer of the electric heat trace may also cause problems such as blistering and cracking. These problems can be caused by poor paint quality, improper application, or defects on the surface of the substrate. The solution is to choose a reliable anticorrosive coating and follow the correct application process to ensure that the surface of the substrate is flat and smooth.
In order to avoid problems with the anti-corrosion layer of electric heat tracing, the following points need to be paid attention to during installation and use:
1.Carefully check the integrity of the anti-corrosion layer before installation, and repair it in time if there is any damage or defect.
2.Avoid mechanical damage to the anti-corrosion layer during installation.
3.According to the use environment, select the appropriate anti-corrosion layer material, such as acid and alkali resistance, high temperature resistance and other special requirements.
4.Regularly maintain and inspect the electric heat tracing, and deal with problems in a timely manner.
The quality of the anticorrosive layer of the electric heat trace is directly related to its service life and safety. Therefore, when choosing an electric heat tracing, in addition to paying attention to its heating performance, it is also necessary to pay attention to the quality of the anti-corrosion layer. At the same time, users should pay attention to the protection and maintenance of the anti-corrosion layer during use to ensure that the electric heat trace can work stably for a long time.
