Flexible Drainage Pipe

Flexible Drainage Pipe

Structural Features:

• Corrugated HDPE or PP pipe wrapped with non-woven geotextile

• Bendable (minimum bending radius ≥5× pipe diameter), lightweight (~0.5-1.2kg/m)

Key Advantages:
✅ Adaptability to Deformation:

• Suitable for areas with uneven settlement (e.g., embankments, slopes)

• Excellent seismic performance (can withstand 5% axial stretching)
  ✅ Self-Filtering Function:

• Geotextile effectively blocks sediment (permeability coefficient ≥5×10⁻³cm/s)
  ✅ Easy Installation:

• Can be transported in coils (saving >50% freight costs)

• Supports trenchless installation (direct burial)

Typical Applications:

• Rainwater infiltration drainage in sponge cities

• Subsurface drainage systems for sports fields

• Agricultural subsurface drainage

International Standards:

• ASTM D7001 (Geotextile-wrapped drainage pipes)

• ISO 10318 (Geosynthetics testing)
