1. Innovative material, reasonable structure, and high strength

The product structure adopts the I-steel load-bearing principle, increasing the moment of inertia and enhancing the hoop stiffness.Double-wall corrugated pipeDemonstrates high mechanical performance. Experimental findings conclude that when the average deformation rate in the vertical direction of the bellows diameter reaches 3.14%, the base pipe can bear a load of up to 60 tons.

2. The corrugated pipe has the characteristics of light weight, material savings, and energy consumption reduction compared to the plain wall corrugated pipe.

Compared to solid wall pipe materials of the same type and specification under the same load, approximately 40% of raw materials can be saved.

3. Double-wall corrugated pipe has a smooth inner surface, allowing for high flow rates. Compared to cast iron and concrete pipes of the same flow rate, it requires a smaller diameter.

The interior surface roughness coefficient is merely 0.009, whereas the concrete pipe's roughness coefficient is 0.0013. In the same pipe diameter, the double-walled corrugated pipe has a water flow capacity 30% greater than the concrete pipe. Authoritative departments conducted hydraulic tests, from which they derived three key characteristics:

① Under the same pipe diameter and flow rate conditions, the use of a bellows can reduce the slope and decrease the burial depth.

② Under the same diameter and slope conditions, the flow can be increased, enhancing the water passage capacity of the pipe material.

③ Under the same flow conditions, plastic corrugated pipes can be selected with a smaller diameter.
