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 systems (intermittent +95°C, continuous +80°C) and gravity stormwater drainage systems installed buried in ground – range of PE100 pipes and fittings – SDR26 (S12.5) – Vacuum stormwater 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-mounted. -BD – intended for use inside buildings or buried in ground within the building perimeter (at a maximum distance of 1 m from it and connected to the building’s sewage system). For this use, only pipes with diameters equal to or greater than 75 mm belonging to series S12.5 are permitted. -Material: high-density polyethylene. -Type: single-layer -Maximum operating temperature: +95°C, intermittent. -Color: black -Joining methods: -Butt welding and electrofusion socket: PE100 SDR26 at 5 bar/-800 mbar and for PE100 SDR33 at 4 bar/-450 mbar under fluid conditions at +20°C and safety factor 1.25. -socket and gasket joint, expansion coupling – maximum 0.5 bar. -mechanical joint with flange. -mechanical joint with threaded fittings.
