NUFLO ORIFICE FLANGE UNIONS
NUFLO ORIFICE FLANGE UNIONS Overview
An orifice plate is one of the most popular primary devices for measuring gases and low-viscosity liquids. The NuFlo Orifice Flange Union helps ensure accurate and predictable measurements by securing the orifice plate’s position in the pipe bore.
The NuFlo Orifice Flange Union is comprised of a set of ANSI flanges machined with differential pressure taps, gaskets, studs, nuts, and jack screws. The jack screws thread directly into each flange and are easily tightened to allow separation of flanges for inspecting or replacing an orifice plate.
Orifice flange unions are available in 1-in. and larger pipe sizes, and a wide variety of pressure ranges, material grades, studs/nuts, and gaskets .
Raised-face flange types can be used with Category 520 orifice plates. Ring-joint flange types can be used with Category 560, 580 or 590 orifice plate holders and universal Category 500 orifice plates. Orifice flange unions do not include an orifice plate; orifice plates and/or orifice plate holders must be ordered separately.
