HDPE Reinforced Winding Pipe | Low-Temperature Tough ,Frost-Crack Resistant | Haierde

Haierde plastic winding pipe is made of high-density polyethylene pellets.
This flexible pipe is manufactured through melt extrusion and winding molding with a unique spiral T-shaped wall structure, which greatly improves ring stiffness and compression resistance. It is specially used for municipal large-diameter rainwater & sewage drainage, river sewage discharge, factory and community buried pipe networks, applicable to heavy-load roads and soft soil foundations.

Core Advantages of Haierde HDPE Reinforced Winding Pipe

  • Large diameter & high ring stiffness: Unique T-shaped hollow wall structure achieves ring stiffness above SN16, solving the pain point of insufficient compression resistance and easy flattening for large-diameter pipes.
  • Flexible spiral structure: Tolerates ±5% uneven foundation settlement and prevents pipe cracking in soft soil or settlement-prone areas.
  • Smooth inner wall & high flow capacity: Its inner wall roughness coefficient (n=0.009) is lower than traditional drainage pipes (n=0.013), boosting water flow by 20%-30%. Smaller pipe diameters can be adopted to solve poor drainage capacity

Why Choose Haierde HDPE Reinforced Winding Pipe?

  • Direct supply from manufacturer: Full-process production supervision to prevent adulterated raw materials.
  • National standard compliance: National official test reports and certifications are provided.

Frequently Asked Questions

Q1: How to get an accurate quotation?

A: Please provide the required nominal outer diameter (DN), ring stiffness grade (SN4/SN8), total purchase length and delivery address. We will calculate the ex-factory price including freight for you.

Q2: What is the service life of Haierde double-wall corrugated pipe?

A: Over 50 years under standard construction.

Q3: What is the difference between double-wall corrugated pipe and winding pipe?

A: Double-wall corrugated pipe (conventional diameter ≤DN800) fits general deep burial; winding pipe can reach DN1500 and above, suitable for large flow and deep burial scenarios.
