MPP power cable protection pipe

As a new type of polymer material pipe, MPP cable protection pipe features excellent corrosion resistance, aging resistance, impact resistance, and UV resistance. Therefore, in various harsh natural environments and engineering conditions, MPP cable protection pipe can maintain good performance, providing long-term and stable protection for cables.

1. Light weight, easy to transport and installation construction; good flexibility, making it convenient and economical when laying. Recyclable, in line with environmental protection requirements; when the pipe bends, the stress in the bending part can be quickly relaxed, no "rebound" phenomenon, easy to construction operation;

2. Small friction loss in the pipe, the conveying fluid capacity of the pipeline is 10% larger than that of PE-X pipe with the same diameter; the impact resistance performance is twice that of PE-X pipe material;

3. The low fracture temperature and excellent low temperature performance of the pipe material make it possible to be constructed in winter under low temperature conditions and no preheating is required when bending the pipe, which can solve the economic losses caused by the inability to construct in northern China due to the low temperature in winter. The minimum bending radius is 5 times of the outer diameter of the pipe;

4. Good chemical corrosion resistance, no rust, long service life.

5. Good creep resistance, the creep of PE-RT pipe changes with the change of temperature, PE-RT does not need cross-linked plate due to special raw materials, once formed after production, the creep is permanent;

6. No toxic additives are added in the production process of pipe materials, smooth inner wall, no scaling, no bacterial growth, can be safely used in drinking water transmission and other fields;

7. Good heat dissipation performance, thermal conductivity is 0.4W/(m • K), can save a lot of energy in heating applications, so PE-RT can give full play to its excellent characteristics in the field of heating;

8. Weldability;

MPP cable protection pipe integrates environmental protection, health, sealing, anti-corrosion, shockproof, high quality, low price, simple construction and other advantages. It has good economic and social benefits in the field of electric power, and has a wide application prospect.

Summary of MPP power cable protection pipe specifications and models

Its specifications and models are mainly distinguished according to the outer diameter, wall thickness and length, the following is a detailed classification of common specifications:

1. Combination of outer diameter and wall thickness

2. Length specification

Common single pipe length is 6 meters, 9 meters, 12 meters.

3. Classification and application scenarios

Excavation type: suitable for conventional cable laying projects.

Non-excavation type (pipe jacking/pull pipe): used for cable protection in special sections such as roads, railways and riverbeds without large-scale damage to the ground.

Suggestions for selection:

Small diameter (such as DN90mm, DN110mm) is mainly used for general cable laying, wall thickness is relatively thin;

Large diameter (such as DN200mm and above) is suitable for ultra-high voltage cables or complex environments (such as crossing roads), and a larger wall thickness is required to enhance the pressure bearing capacity.

4. Connection mode

The connection mode of MPP cable protection pipe is also part of its specifications. Common connection modes include socket connection, hot fusion connection, electric fusion connection, etc. Different connection modes are suitable for different application scenarios and engineering requirements. Choosing the appropriate connection mode can ensure the safety and reliability of cable pipeline.

When selecting MPP cable protection pipes, it is essential to consider the specific project requirements, construction conditions, and the specifications and characteristics of the cables, ensuring that all specifications are compatible. Additionally, to ensure the quality and safety of the cable pipes, it is crucial to choose reputable manufacturers and high-quality products. During construction, it is important to follow relevant construction standards and technical requirements to ensure the installation quality and effectiveness of the cable pipes.

In short, MPP cable protection pipe specifications are diverse, and the selection of appropriate specifications and connection mode is crucial for cable protection. In practical application, it is necessary to consider and select according to specific conditions to ensure the safety, reliability, economy and practicality of cable pipeline.
