Excellent performance
- 1 Lightweight, making it easy to transport and install; it has good flexibility, making it convenient and cost-effective to lay. It is recyclable, meeting environmental standards; when pipes bend, the stress in the bent section can be quickly relieved, preventing the 'rebound' phenomenon, which facilitates construction operations and avoids damage to the bent sections of the pipes due to stress concentration during use;
- 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 PE-X pipe material Double that;
- 3 The fracture temperature is low, and the pipe has excellent low-temperature performance. Its 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 resistance is permanent after production and forming;
- 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 of 0.4W/(m • K), can save a lot of energy in heating applications, so the use of PE-RT in heating field can give full play to its excellent characteristics;
- 8 Weldability
Overall merit
As a critical material in power engineering construction, MPP power pipes are essential for ensuring the safe operation of cable lines. Polypropylene is known for its high strength, toughness, and excellent heat resistance, corrosion resistance, and electrical insulation properties. Modified polypropylene further enhances these fundamental properties.
MPP power pipe has become an indispensable important material in power engineering construction with its excellent material characteristics and wide application fields.
Parameter
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 should be selected 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, and 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 the construction process, it is necessary 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 has a variety of specifications, and the selection of appropriate specifications and connection mode is very important for cable protection. In practical application, it is necessary to consider and choose comprehensively according to the specific situation, so as to ensure the safety, reliability, economy and practicality of cable pipeline.
