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 from (electro)welded PE100 pipes and fittings. Characteristics – 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 of 5 bar/-800 mbar and for PE100 SDR33 of 4 bar/-450 mbar under fluid conditions at +20°C and safety coefficient 1.25. – socket and gasket joint, expansion coupling – maximum 0.5 bar. – mechanical flange joint. – mechanical threaded fitting joint.
