Orifice flange

An orifice flange provides a flanged joint around an orifice measurement element and access for differential-pressure connections. ASME B16.36 establishes the standards context for flanges with orifice pressure-differential connections, but the Fittopipe title alone does not establish compliance or a particular detail arrangement. Selection should verify flange style, compatibility with the plate and measurement system, pressure-tap arrangement and installation documents. An orifice plate, jack screws, facing or pressure class is not assumed to be included or fixed.
