Product Introduction

Steel‑belt‑reinforced HDPE spiral pipe is a new type of pipeline composed of high-density polyethylene (HDPE) material combined with a helical steel‑belt reinforcement structure.

HDPE material exhibits excellent corrosion resistance, chemical resistance, and a smooth inner wall surface; the helical steel‑strip reinforcement layer enhances the pipe’s ring stiffness and overall structural strength.

Compared with conventional HDPE pipes, steel‑reinforced HDPE spiral pipes offer superior resistance to external pressure and deformation, making them well suited for large‑diameter underground drainage systems and engineering applications subjected to substantial external loads.

Widely used in

Mine drainage system, tailings pond drainage system, stormwater drainage system, underground drainage pipelines, and industrial wastewater conveyance system.

Product Features

1. High ring stiffness and excellent structural strength

The helical steel‑strip reinforcement provides additional support to the pipeline, enhancing its resistance to external pressure, soil loads, and foundation deformation.

Suitable for deep underground, large-diameter drainage projects.

2. Excellent corrosion resistance

The HDPE‑coated steel strip structure effectively prevents corrosion of the steel. It exhibits excellent resistance to acids, alkalis, salts, and chemical media, making it suitable for demanding underground and industrial environments.

3. Supports large-aperture applications

Steel‑belt‑reinforced HDPE spiral pipes can be manufactured in large diameters to meet high‑flow drainage requirements. They are suitable for mine drainage projects, large underground drainage systems, and industrial wastewater‑disposal applications.

4. Smooth inner wall for high conveying efficiency

The smooth inner wall of HDPE reduces frictional resistance, enhancing fluid flow efficiency. At the same time, it minimizes sediment buildup, the risk of pipe blockages, and subsequent maintenance costs.

5. Lightweight and easy to install

Compared with traditional steel and concrete pipes, these products are lighter in weight, easier to transport, and offer higher installation efficiency, thereby effectively reducing construction complexity and installation costs.

6. Long service life

The corrosion resistance of HDPE, combined with a steel‑belt reinforcement structure, ensures the pipeline’s long‑term stable operation in harsh environments.
