The maintenance and maintenance of MPP cable protection pipe is an important measure to ensure its long-term stable operation and prolong its service life. Here are some specific maintenance and upkeep methods:

1. Daily inspection

1. Visual inspection: Regularly inspect the appearance of the MPP cable protection pipe to see if there is any deformation, damage or aging. Pay special attention to whether the pipe connections are strong and whether there are signs of deformation or breakage.

2. Working state inspection: Although the internal state of the buried MPP cable protection pipe cannot be directly observed, it can be judged indirectly by checking the working status of the power equipment or system related to it. For example, check the insulation resistance, leakage current, and other parameters of the cable to evaluate whether the MPP cable protection tube has played an effective role in protecting the cable.

2. Cleaning and maintenance

1. Surface cleaning: Use a soft cloth or cotton swab dipped in an appropriate amount of detergent to wipe the MPP cable protection tube to remove surface dirt and impurities. Be careful not to use excessively rough items for cleaning to avoid damaging the surface of the pipe.

2. Anti-corrosion treatment: Regularly apply anti-rust agent on the surface of the MPP cable protection pipe to prevent the metal part from rusting. Especially for MPP cable protection pipes with metal connectors or accessories, anti-corrosion treatment should be strengthened.

3. Moisture-proof and sunscreen-proof

1. Moisture-proof measures: Make sure that the MPP cable protection pipe is placed in a dry, well-ventilated environment to avoid moisture affecting the pipe. For buried MPP cable protection pipes, it should be ensured that the backfill material has good drainage performance to avoid damage to the pipeline caused by stagnant water.

2. Sun Protection: Avoid MPP cable protection pipe from prolonged exposure to sunlight, especially strong ultraviolet rays can cause damage to the pipe material. When installed outdoors, shade or use a sunscreen coating to protect the pipes.

4. Reasonable stacking and transportation

1. Correct stacking: When stacking MPP cable protection tubes, care should be taken to avoid surface damage caused by excessive pressure. At the same time, the stacking height is controlled to reduce the pressure on the bottom pipe and ensure that the stacking environment is dry and ventilated.

2. Safe transportation: During transportation, it is necessary to handle it with care and avoid behaviors that may cause damage to the pipeline, such as throwing and falling at will. At the same time, appropriate fixing measures should be taken to prevent the pipeline from sliding or colliding during transportation.

5. Professional maintenance

1. Regular inspection and maintenance: Hire a professional team to conduct regular inspection and maintenance of MPP cable protection pipes, including checking the connection of the pipeline, whether the anti-corrosion layer is intact, whether there is external damage, etc. Problems found should be dealt with in a timely manner to avoid the problem from expanding.

2. File management: Establish a sound MPP cable protection pipe file management system to record the installation, maintenance, inspection and other information of pipes. Through file management, we can understand the operation status of pipes in time and provide strong support for the maintenance and management of pipes.

To sum up, through daily inspection, cleaning and maintenance, moisture and sun protection, reasonable stacking and transportation, and professional maintenance, we can ensure that the MPP cable protection pipe remains in a safe and reliable state and prolongs its service life during long-term use.
