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 wastewater drainage systems (intermittent +95°C, continuous +80°C) and gravity stormwater drainage installed buried in the ground – range of PE100 pipes and fittings – SDR26 (S12.5) – Vacuum stormwater drainage, made from (electro)welded PE100 pipes and fittings. Features – 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 in the ground within the building perimeter (at a maximum distance of 1 m from it and connected to the building’s drainage system). For this use, only pipes with diameters of 75 mm or larger belonging to the S12.5 series are permitted. – Material: high-density polyethylene. – Type: single-layer – Maximum operating temperature: +95°C, intermittent. – Color: black – Jointing methods: – Butt welding and electrofusion coupling: PE100 SDR26 at 5 bar/-800 mbar and PE100 SDR33 at 4 bar/-450 mbar, with fluid at +20°C and a safety factor of 1.25. – Socket-and-gasket joint, expansion sleeve – max. 0.5 bar. – Mechanical joint with flange. – Mechanical joint with threaded fittings.
