Ultra Wide Range Flange Adaptor Ductile Iron PN16

The ultra wide range flange adaptor is an engineered piping solution designed to connect plain-ended pipes of diverse materials—including steel, ductile iron, grey cast iron, asbestos cement, and PVC—directly to standard flanged fittings, valves, and pumping equipment. Fabricated with a robust ductile iron GGG-50 body, this wide-tolerance fitting compensates for extensive variations in pipe outer diameters, accommodating dimensional deviations from DN65 up to DN300. Engineered for an operational nominal pressure of 16 bar (PN16), the adaptor ensures a leak-tight, reliable transition across mismatched pipeline materials, making it an essential component for network extensions, scheduled maintenance, and emergency pipeline rehabilitation.

Corrosion protection and long-term durability are ensured by an electrostatically applied epoxy powder coating in RAL 5015, which provides robust defense against aggressive soil conditions, groundwater, and industrial environments in both underground buried installations and above-ground plant rooms. The internal sealing profile incorporates a high-grade EPDM elastomeric gasket compliant with drinking water hygiene standards, maintaining effective hydraulic containment under working pressures up to 16 bar. The wide tolerance range allows installation teams to bridge dimensional discrepancies without requiring specialized bespoke couplings or extensive inventory on site, significantly simplifying assembly and reducing downtime.
