Enables the mechanical jointing of a flange and a pipe, of different materials and outside diameters. Description: -Wide tolerance range: an average of 29mm. -Small number of models for a Nominal Diameter. -High performance: Permanent leak tight joint when compressing the gasket between the end ring and the sleeve onto the pipe. Anticorrosion protection: epoxy powder coating (250 μm) and Geomet 500® Gr. B for the bolts. -Ease and speed of installation: -Angular deflection ±6°. -Accommodates misalignment. -Absorbs expansion and contraction. -Important setting gap. Conformity to standards: -NF A 48-830: Foundry products - Spheroidal graphite cast iron fittings for PVC drinking water pipes under pressure. - EN 545: Ductile iron pipes, fittings, accessories and their joints for water pipelines - requirements and test methods. - EN 1092-2: Flanges and their joints.Part 2: Cast iron flanges. - ISO 2531: Ductile iron pipes, fittings, and accessories and their joints for water applications. - ISO 7005-2: Metallic flanges and cast iron flanges. - ISO 7483: Dimensions of gaskets for use with flanges to ISO 7005 Approval:- Drinking water approved.
