Properties of VESBO Corrugated Pipes Dimensions

VESBO Corrugated pipes are classified according to their ring stiffness. DN / ID SN Length (m) d e (mm) d i (mm)
(mm)
Rigidity is the measurement of resistance of the pipe against ring 100 4 8 6. 7 118-119 100.0-101.1

• SN4 (4.0 kN/m² = 400 kg/m²) for off traffic areas and Installation of VESBO Corrugated Pipes
• SN8 (8.0 kN/m² = 800 kg/m²) for areas with traffic load should be
