How many types of hoop stiffness are there for the PE steel corrugated pipe?

A PE steel strip reinforced spiral pipe is a double-wall spiral corrugated pipe made by forming a steel strip into a wavy shape with a high-density polyethylene (PE) matrix and coated with an adhesive resin on the surface, serving as the main supporting structure, and then wrapped and compounded with polyethylene material to form an integrated structure.

Its characteristics mainly include the following points:

High strength: Due to the reinforcing effect of the steel strip, the pipe material has a high hoop stiffness, capable of withstanding greater external pressure.

2. Corrosion Resistance: PE material boasts excellent chemical resistance, allowing for long-term use in a variety of harsh environments.

3. Excellent Sealing: The joints are sealed with heat-fused welding or rubber rings to ensure the tightness of the pipeline system, minimizing the risk of leakage.

4. Good flexibility: Capable of adapting to a certain degree of uneven ground settlement and geological disasters such as earthquakes.

5. Longevity: Extended lifespan under normal operating conditions.

6. Easy to Install: Relatively lightweight with quick setup, reducing construction time and costs.

7. Low flow resistance: Smooth inner wall reduces flow resistance and enhances water conveyance capacity.
