HDPE Double-Wall Corrugated Pipes by Zhongtong

Zhongtong specializes in producing high-density polyethylene (HDPE) double-wall corrugated pipes. These pipes are made from high-density polyethylene, featuring a smooth inner wall and a corrugated outer wall, both of which are hollow. They are primarily used for buried sewage and drainage systems.

The design of the “Zhongtong” HDPE double-wall corrugated pipe includes a double-layer wall at the socket. During production, the socket is expanded online, which prevents the deformation commonly seen in thin single-layer pipes. This double-wall design makes the pipe very sturdy. A natural rubber sealing ring is used for flexible connections, making installation easy and reliable. These pipes are designed to minimize leaks, offering a low overall cost and a service life of up to 50 years.

Performance Characteristics:

1. Unique Structure: The pipes have a strong pressure resistance due to their unique design.
2. Smooth Inner Wall: The smooth inner wall allows for high flow rates.
3. Easy Connection: Connections are straightforward, well-sealed, and corrosion-resistant. This prevents leaks and avoids secondary pollution, making these pipes an ideal green choice.
4. Flexural Properties: The pipes exhibit good flexibility, adapting well to uneven soil settlement.
5. Longevity: These pipes can last over 50 years in various geographical conditions.
6. Lightweight Construction: Their lightweight nature makes them easy to handle, reducing construction costs and time.
7. Wear Resistance: At a speed of 15 feet per second, they show 3 to 5 times better wear resistance compared to ordinary or fine-grained steel pipes.

In conclusion, Zhongtong’s HDPE double-wall corrugated pipes are a reliable, efficient, and sustainable choice for sewage and drainage applications.
