Rigid Drainage Pipe

Rigid Drainage Pipe - Structural Water Management Solution

High-Performance Drainage Technology

Our rigid drainage pipe is engineered for heavy-duty water management, featuring robust construction and precision hydraulic performance for demanding civil and industrial applications.

Material & Design Advantages

• High-strength PVC or HDPE (double-wall corrugated design)

• Smooth interior for optimal flow efficiency (Hazen-Williams C=150)

• Crush-resistant (≥12 kN/m² ring stiffness for deep burial)

Key Benefits

✅ Superior Load-Bearing Capacity – Supports heavy traffic and deep burial (up to 10m cover)
✅ Precision Water Control – Engineered perforations (optional) for targeted drainage
✅ Long-Term Durability – Resistant to chemicals, abrasion, and UV degradation

Ideal Applications

1. Transportation Infrastructure – Highway edge drains, railway culverts

2. Urban Drainage – Stormwater systems, municipal sewer networks

3. Industrial Sites – Factory yard drainage, landfill leachate collection

4. Agricultural Drainage – Subsurface field drainage, irrigation channels

Technical Specifications

Installation & Performance

• Modular Design – Easy coupling with gasketed joints (leak-proof)

• High Flow Efficiency – Low friction coefficient (Manning’s n ≈ 0.009)

• 50+ Year Lifespan – Tested for long-term structural integrity

Selection Guide

• Standard PVC – Cost-effective for shallow burial (≤4m)

• Heavy-Duty HDPE – Ideal for deep burial and high-load zones

• Perforated vs. Solid – Choose based on drainage needs (seepage vs. conduit flow)

Note: For optimal performance, pair with proper geotextile filtration in fine-soil conditions. Consult our engineering team for custom hydraulic designs.
