Today, we're here to talk about the benefits of Sichuan HDPE double - wall corrugated pipes.

Sichuan HDPE double - wall corrugated pipes offer the following prominent advantages:

1. Superior Corrosion Resistance: The material of HDPE double - wall corrugated pipes undergoes special treatment, enabling long - term service in harsh environments without being corroded. It can maintain stable performance against the erosion of acids, alkalis and other chemical substances.
2. High Strength and Pressure Resistance: HDPE corrugated drainage pipes feature a high density ratio and strong pressure - bearing capacity, which can withstand relatively high pressure and ensure the integrity and stability of the pipeline.
3. Excellent Wear Resistance and Impact Resistance: This type of pipeline is not easily damaged by external forces during use, can maintain good performance for a long time, reduce the frequency of maintenance and replacement, and save human and material costs.
4. Favorable Environmental Performance: HDPE double - wall corrugated pipes contain no pollutants or harmful substances, causing no environmental pollution. Moreover, the material is recyclable and reusable.
5. Strong External Pressure Resistance: The annular corrugated structure of the outer wall significantly enhances the ring stiffness of the pipe, allowing it to better resist soil loads.
6. Low Project Cost: Under equal load conditions, HDPE double - wall corrugated pipes only need thinner pipe walls to meet the requirements, thus saving a large amount of raw materials and reducing the project cost.
7. Convenient Construction: The lightweight material makes transportation and connection simple and fast, shortens the construction period, and facilitates maintenance work.
8. Long Service Life: The service life of buried pipes can reach more than 50 years, reducing the replacement frequency.
9. Wide Temperature Application Range: The pipeline will not crack in an environment of - 60℃, and the temperature of the conveyed medium can reach up to 60℃.
10. Comprehensive Low Project Cost: Compared with concrete pipes, it has lower operation costs, and no foundation treatment is required when the soil quality is good.
11. Low Permeability Rate: The permeability rate is lower than 2%, effectively preventing secondary pollution of groundwater.
12. Smooth Inner Surface: It is not prone to scaling and can keep the pipeline unobstructed.
    
    

These advantages make HDPE double - wall corrugated pipes perform well in various projects, and they are widely used especially in urban drainage systems and farmland drainage projects.
