• Product Overview:

Polyethylene (PE) steel strip reinforced spiral corrugated pipe is a new type of composite pipe material with high-density polyethylene (HDPE) as the inner and outer layers, and high-strength steel strip reinforcement body embedded in the middle. It perfectly combines the excellent corrosion resistance of HDPE and the high modulus of the steel strip, creating a “heavy-duty” drainage and sewage pipeline solution with extremely high ring stiffness and excellent impact resistance. It is an ideal alternative to traditional materials such as concrete pipes and cast iron pipes.

• Key selling points:

Ø Ultra-high ring stiffness – Can withstand heavy loads and deep burial pressure, up to SN12.5

Ø Excellent corrosion resistance – Resists corrosion from acidic and alkaline soils as well as industrial wastewater, with a lifespan exceeding 50 years

Ø Unique structural design – Perfectly combines polyethylene and steel strips, offering both flexibility and rigidity

Ø Quick installation – Connection by shrink sleeve, socket-type hot melt connection, socket gasket connection, with excellent sealing performance and high construction efficiency

Ø Environmentally friendly and safe – Made of HDPE material, non-toxic and odorless, 100% recyclable

• Structure and Advantages:
• Three-layer composite structure, with outstanding performance:
• Inner layer: Smooth HDPE layer, with low friction coefficient, strong water permeability, and no tendency to form deposits.
• Middle layer: High-strength steel strip reinforcement layer, providing the required hoop stiffness and compressive strength for the pipeline.
• Outer layer: Anti-aging and impact-resistant HDPE protective layer, effectively protecting the steel strip from corrosion.

• Core advantages:

1. Outstanding carrying capacity: The addition of steel strips significantly enhances the hoop stiffness of the pipe (SN8, SN10, SN12.5), enabling it to withstand harsh environments such as deep soil cover and heavy vehicle pressure.
2. Excellent chemical stability: Both the inner and outer walls are made of HDPE, which is inert to most acid, alkali, and salt media. No anti-corrosion treatment is required, and its service life is much longer than that of metal and concrete pipes.
3. Reliable connection, zero leakage: It adopts socket-type electric hot-melt connection. The interface strength is higher than that of the pipe body, forming a perfect sealing system, which fundamentally prevents leakage and protects groundwater resources.
4. Lightweight and convenient construction: Compared to pipes of the same specification made of cement, its weight is only 1/10. Transportation, hoisting, and installation are simple, significantly reducing construction costs and time.
5. Good flexibility, resistance to foundation settlement: Its good flexibility enables it to adapt to a certain degree of foundation settlement or earthquakes, making it safer.

• Frequently Asked Questions (FAQ)

1. Q: What are the differences between PE steel tape reinforced pipes and double-wall corrugated pipes?
   A: The main difference lies in the reinforcement material. Double-wall corrugated pipes rely entirely on the HDPE corrugated structure to provide rigidity, while steel tape reinforced pipes have steel tapes embedded in the middle, resulting in higher ring rigidity and the ability to withstand greater burial depth and loads. They are suitable for more demanding engineering projects.
2. Q: Will the steel belt rust? How can the service life be guaranteed?
   A: No. The steel belt is completely enclosed within a corrosion-resistant HDPE layer, completely isolated from the external environment (water, air, soil), fundamentally eliminating the possibility of rusting and ensuring an ultra-long service life of over 50 years for the pipeline.
3. Q: What should be noted during installation?
   A: The foundation should be flat and continuous. After laying, it needs to be backfilled in layers and compacted. We provide detailed installation instructions and on-site technical guidance.
4. Q: Do you offer customization for non-standard sizes?
   A: Yes. We can tailor the pipe to specific diameters, lengths and ring stiffness according to your engineering drawings and specific requirements.
