PVC-KG Elbow SN8 single socket

  Datasheet (PDF)

PVC-KG SN8 SDR 34 single-socket elbows are engineered for directional routing changes in non-pressure underground gravity sewer and rainwater drainage networks installed outside building footprints. Manufactured from high-grade unplasticized polyvinyl chloride (PVC-U), these robust fittings provide a nominal ring stiffness of 8 kN/m2 (SN8 / SDR 34), ensuring outstanding structural resistance suitable for trench installations at burial depths between 0.8 and 6 meters under medium to heavy road traffic loading. Each fitting integrates a single factory-formed socket equipped with an EPDM elastomeric sealing ring alongside a precision-chamfered spigot end, ensuring rapid push-fit assembly and long-term leak tightness capable of absorbing minor axial shifts and soil settlements without joint compromise. The exceptionally smooth internal bore achieves high hydraulic transport performance with an absolute Manning roughness coefficient of 0.01, reducing flow resistance, preventing incrustations, and minimizing sediment accumulation during operational cycles. Highly resistant to chemical degradation, the durable PVC-U body tolerates aggressive soils, salts, caustic fluids, and acidic discharges across a pH range of 2 to 12, sustaining continuous wastewater temperatures up to 60 degrees. Engineered for an operational service life of at least 50 years, these elbows provide dependable geometric transitions across standard configurations of 15, 30, 45, and 87 degrees, ensuring total system compatibility with gravity collector pipelines.
