High-density polyethylene elbows, used in: – Domestic (intermittent +95 °C, continuous +80 °C) and gravitational rainwater drainage systems inside high-rise buildings, public buildings, industrial halls. – Ventilation columns for drainage systems. – Domestic (intermittent +95 °C, continuous +80 °C) and gravitational rainwater drainage systems installed underground – PE100 pipes and fittings range – SDR26 (S12.5). – Vacuum rainwater drainage, made of (electro)welded PE100 pipes and fittings. Characteristics: -Diameter range: (fi)32, (fi)40, (fi)50, (fi)56, (fi)63, (fi)75, (fi)90, (fi)110, (fi)125, (fi)160, (fi)200, (fi)250, (fi)315. -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 socket: PE100 SDR26 for 5 bar/-800 mbar and for 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.
