High-density polyethylene elbows, used in: – Domestic (intermittent +95°C, continuous +80°C) and gravitational rainwater drainage systems within high-rise buildings, public buildings, and industrial halls. – Ventilation stacks for drainage systems. – Domestic (intermittent +95°C, continuous +80°C) and gravitational rainwater drainage systems installed underground – PE100 pipe and fitting range – SDR26 (S12.5). – Vacuum rainwater drainage systems, made from (electro)welded PE100 pipes and fittings. Characteristics: – Diameter range: Ø32, Ø40, Ø50, Ø56, Ø63, Ø75, Ø90, Ø110, Ø125, Ø160, Ø200, Ø250, Ø315. – Compliance: EN 1519. – Series: S12.5 for SDR26 and S16 for SDR33. – Application classes: – B – intended for use inside and outside buildings, wall-anchored. – BD – intended for use inside buildings or buried underground within the building’s perimeter (at a maximum distance of 1 m from it and connected to the building’s drainage system). For this application, only pipes with diameters equal to or greater than 75 mm belonging to the S12.5 series are permitted. – Material: High-density polyethylene. – Type: Monolayer. – Maximum operating temperature: +95°C, intermittently. – Color: Black. – Joining methods: – Butt welding and electrofusion coupling: PE100 SDR26 for 5 bar/-800 mbar and PE100 SDR33 for 4 bar/-450 mbar under fluid conditions at +20°C and a safety factor of 1.25. – Socket and gasket joint, expansion sleeve – maximum 0.5 bar. – Mechanical flange joint. – Mechanical joint with threaded fittings.
