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