The service life of MPP cable protection tubes is usually around 50 to 60 years, but the specific service life can be affected by a variety of factors.

Influencing factors

1. Material Properties: The main material of MPP cable protection tube is modified polypropylene (MPP), which has excellent heat resistance, aging resistance, solar ultraviolet resistance, corrosion resistance and other properties, which help to extend its service life.

2. Construction technology and installation quality: In the installation process of MPP cable protection pipe, if it is operated in strict accordance with the relevant specifications and standards to ensure that the pipeline is tightly connected, laid smoothly, and landfilled meets the requirements, its service life can be significantly improved. On the contrary, if there are problems such as non-standard operation, poor pipe connection, and damage to the pipeline during laying, etc., it may lead to potential safety hazards such as leakage and rupture of the MPP cable protection pipe during use, thereby shortening its service life.

3. Use environment: The use environment of MPP cable protection pipe will also have a certain impact on its service life. In harsh natural environments, such as high temperature, low temperature, strong ultraviolet rays, acid and alkali corrosion, etc., the service life of MPP cable protection pipe may be affected to a certain extent. Therefore, when selecting MPP cable protection tubes, it is necessary to comprehensively consider the actual use environment and select the appropriate model and specifications.

4. Maintenance and maintenance: In the process of use, strengthen the maintenance and maintenance of MPP cable protection pipes, find and deal with problems in time, such as regularly checking the connection of the pipeline, preventing external damage, etc., can ensure that it is in good working condition for a long time, so as to prolong its service life.

To sum up, the service life of MPP cable protection tube is the result of a combination of factors. Under ideal use conditions, its service life can reach more than 50 years, but the specific service life needs to be determined according to the specific use environment and maintenance conditions. Therefore, in order to prolong the service life of MPP cable protection tubes, the above factors need to be considered comprehensively and corresponding measures should be taken.
