uPVC Sewer Pipe — SN2
Gravity-flow uPVC sewer and drainage pipe systems engineered for municipal and commercial infrastructure.
uPVC Sewer Pipe — SN2
uPVC Sewer & Drain Pipes
Lightweight SN2 gravity sewer pipe for shallow installations and low-traffic zones. Ideal for residential drain connections, garden drainage, and low-load municipal sewer laterals where burial depth is minimal.
Applications
- Municipal Sewerage Networks
- Storm Drainage Systems
- Commercial Building Drainage
- Industrial Effluent Disposal
- Road & Highway Drainage
Industries
Engineered Performance
Technical advantages built into every unit in this range.
Chemical & Biological Resistance
PVC formulation resists aggressive sewage chemistry, hydrogen sulphide, and microbial attack — maintaining full structural integrity over a 100-year design life.
Low Friction Coefficient
Manning's n = 0.009 smooth bore dramatically improves flow capacity and self-cleansing velocity versus traditional materials, reducing blockage risk.
Structural Ring Stiffness
SN2, SN4, and SN8 classes provide graduated stiffness options for varying installation depths and traffic loading conditions.
Rubber Ring Socket Joints
Factory-formed integral socket with EPDM rubber ring seal — provides watertight performance at ±2° angular deflection for ground movement accommodation.
Light Weight, Easy Handling
1/5th the weight of concrete pipes enables manual handling and faster installation without heavy lifting equipment, reducing labour costs significantly.
Full Test Certification
Every production batch undergoes ring stiffness, impact resistance, and hydraulic pressure testing with full traceability documentation for project compliance.
