Used in: – Domestic sewage systems (intermittent +95C, continuous +80C) and gravity stormwater drainage inside high-rise buildings, public buildings, industrial halls. – Ventilation stacks for sewage systems. – Domestic sewage systems (intermittent +95C, continuous +80C) and gravity stormwater drainage installed buried in ground – range of PE100 pipes and fittings – SDR26 (S12.5) – Stormwater drainage in vacuum regime, made of PE100 (electro)welded pipes and fittings. Electrofusion joining can be performed for both existing installations and for modifications, repairs or for making prefabricated assemblies. The thermal energy produced by the resistance under voltage applied by the welding machine causes heating, melting and welding of the materials. Equipped with stop limiter, which when removed allows the coupler to slide on the pipe for repairs. Type of joint: non-detachable, tensile resistant. Characteristics – Diameter range: (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: +95C, intermittent. – Color: black – SafeKit system joining methods: – Butt welding and electrofusion coupler: PE100 SDR26 of 5 bar/-800 mbar and for PE100 SDR33 of 4 bar/-450 mbar under fluid conditions at +20C and safety coefficient 1.25. – Joining with coupler and gasket, expansion sleeve – maximum 0.5 bar. – Mechanical joining with flange. – Mechanical joining with threaded fittings.
