Gravity sewer pipes
ULPI® rigid U-PVC Gravity Sewer Pipes SN4
These pipes are designed for underground storm water, gravity sewerage and drainage networks, in compliance with NL EN 1401.
This range of pipes SN4 (ring stiffness &ge 4kN/m2) is perfectly adapted for urban sewer networks under normal conditions with traffic load.
SN4 sewer pipes can be directly buried underground between 0.9 and 6 m depth. (expected average deflection less than 8%).
ULPI® rigid U-PVC Gravity Sewer Pipes SN8
This range of pipes SN8 (ring stiffness &ge 8kN/m2) is perfectly adapted for urban sewer networks under Heavy-Duty soil conditions with traffic load.
SN8 sewer pipes can be directly buried underground between 0.6 and 9 m depth. (expected average deflection less than 8%).
