PVC-KG Branch 45° SN4

  Datasheet (PDF)

PVC-KG branch 45 degrees and 67 degrees SN4 KGEA is an engineered junction fitting designed for non-pressure underground gravity sewer and rainwater drainage systems outside building structures. Manufactured from durable unplasticized polyvinyl chloride in standard sewer orange (RAL 8023), this external drainage fitting establishes secondary lateral connections into main collector pipelines at hydraulic branch angles of either 45 degrees or 67 degrees. Engineered with a nominal ring stiffness of SN4 (4 kN/m²), the fitting possesses outstanding mechanical resistance and structural flexibility, safely redistributing external soil loads and backfill pressures while maintaining complete mechanical compatibility with both SN4 and SN2 sewer networks. Joint integrity is achieved via integrated push-fit sockets factory-fitted with high-durability elastomeric EPDM lip seals, providing leak-tight jointing that accommodates ground settlement, pipe expansion, and axial displacement within permissible technical tolerances. The branch features an ultra-smooth interior surface with minimal hydraulic roughness, substantially enhancing flow rates, maximizing hydraulic capacity, and preventing the adhesion of solids, sludge, and encrustations throughout prolonged operational lifecycles. Structurally resistant to chemical aggression across a wide pH range from 2 to 12, the fitting exhibits inert performance against corrosive soils, household wastewater, caustic effluents, dilute acids, and salts. It operates reliably under continuous effluent discharge temperatures up to 60 degrees Celsius, with elevated short-term thermal resilience. By facilitating efficient lateral fluid convergence, the TeraPlast PVC-KG branch provides long-term operational integrity and dependable routing for municipal wastewater infrastructure, civil development drainage, and industrial gravity networks.
