Hexagonal corrugated pipe reinforced drainage power protection pipe hexagonal composite structure wall pipe

Hexagonal corrugated pipe

Hexagonal Corrugated Pipe is a reinforced plastic pipe with a hexagonal corrugated structure. It is specially designed to increase ring stiffness while maintaining lightweight, and is suitable for high load drainage, cable protection, and other scenarios. The following are its core features and selection guidelines:

1、 Structural characteristics

Hexagonal ripple reinforcement:

The outer wall has hexagonal continuous ripples, forming a honeycomb shaped support structure. The ring stiffness can reach SN8-SN16, and the compressive strength is 30% higher than that of traditional circular corrugated pipes.

The inner wall is smooth (roughness coefficient ≤ 0.01), ensuring water delivery and preventing sedimentation.

Material selection:

HDPE (high-density polyethylene): corrosion-resistant, impact resistant, suitable for temperature range of -60 ℃~60 ℃.

PVC (polyvinyl chloride): Low cost, good flame retardancy, suitable for low-voltage cable protection.

2、 Core advantages

3、 Compression resistance: The hexagonal structure disperses external loads and can be buried up to 6-8 meters deep (ordinary corrugated pipes are usually 4-6 meters).

Lightweight construction: Weighing only 1/10 of a concrete pipe, it supports non excavation traction and reduces construction costs.

Environmental Protection: HDPE material is recyclable, with a design lifespan of over 50 years and no risk of chemical pollution.

3、 Application scenarios

Municipal engineering: highway and railway subgrade drainage system.

Power communication: The hexagonal structure is resistant to settlement and deformation, protecting the safety of underground cables.

Mining metallurgy: Strong wear resistance, capable of transporting high wear media such as slurry and tailings.

Agricultural irrigation: UV resistant, suitable for long-term outdoor use.

4、 Selection suggestions

Municipal drainage: Choose HDPE hexagonal corrugated pipe SN12.5, buried at a depth of 6 meters, suitable for heavy traffic areas.

Cable protection: PVC hexagonal tube SN8 is selected, which is low-cost and easy to cut, suitable for strong and weak electrical wiring.

Mining scene: HDPE+anti-static coating model to prevent safety hazards caused by mineral powder adhesion.
