**Seven Key Properties and Application Range of Steel Belt Reinforced Pipe**
Steel belt reinforced pipe, also known as buried steel-reinforced high-density polyethylene (HDPE) spiral corrugated pipe (MRP), is a modern type of plastic drainage pipe developed in China in recent years. This innovative product combines the strength of steel with the flexibility and corrosion resistance of polyethylene. It is manufactured by compressing a continuous steel strip into a spiral rib structure, which is then wrapped between two inner and outer layers of heat-sealed HDPE. The result is a durable and efficient pipe that offers superior performance for underground applications.
The production diameter ranges from 300 mm to 2200 mm, with lengths typically between 6 and 10 meters. The pipe can achieve ring stiffness ratings of SN8, SN12.5, SN16, and SN18, significantly improving upon traditional large-diameter plastic pipes that were previously limited to SN8. This makes it ideal for demanding engineering environments where structural integrity is essential.
One of the key advantages of steel belt reinforced pipe is its versatility in connection methods, allowing it to meet various construction needs. It provides excellent sealing, reliability, and ease of installation, reducing maintenance and long-term costs.
**Key Performance Features:**
1. **Low Friction Coefficient**: The smooth inner surface minimizes fluid resistance, enhancing flow efficiency.
2. **Anti-Scaling**: Due to its low surface adhesion, the pipe resists fouling and scaling, maintaining optimal performance over time.
3. **Easy Connection**: It can be directly flanged without welding, eliminating issues like broken fittings caused by poor welds.
4. **Corrosion Resistance**: Highly resistant to most acids, alkalis, and salts, except for some strong oxidizing agents under high temperature.
5. **Fire Retardant and Anti-static**: Meets all necessary safety standards for fire resistance and static control.
6. **Long Service Life**: With a lifespan exceeding 20 years, it offers significant economic benefits.
7. **Non-Fouling and Corrosion Resistant**: Its self-lubricating properties reduce friction, and the inner wall is resistant to wear, corrosion, and fouling.
Compared to steel pipes, the inner diameter of this pipe can be reduced by up to 15.4%, making it more space-efficient. This feature is particularly beneficial in applications such as fly ash discharge systems in thermal power plants, as well as pipelines for crude oil and mud.
The material demonstrates excellent chemical resistance, capable of withstanding a wide range of corrosive media, including acids, alkalis, and salts, as well as many organic solvents. In tests, it was immersed in 80 different organic solvents at 80°C for 30 days with no visible damage or changes in physical properties.
**Applications Include:**
- Sewage treatment plant filtrate collection pipelines
- Industrial wastewater discharge systems
- Waste management facilities
- Highway and municipal drainage networks
- Cable and conduit protection systems
- Water collection and seepage control systems
- Coastal, rainwater, and irrigation pipelines
This versatile and durable piping solution is an excellent choice for a wide range of infrastructure and industrial projects.
