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 underground – range of PE100 pipes and fittings – SDR26 (S12.5). – Vacuum stormwater drainage systems, made of PE100 (electro)welded 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 within the building perimeter (at a maximum distance of 1 m from the building 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 coupling: 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.
