Orifice Weld Neck RF flanges ASME B16.36 Class 300

Dimensions Orifice Weld Neck RF Flanges ​Information

Orifice Weld Neck flanges are specialized flanges used in orifice metering systems to facilitate accurate measurement of fluid flow rates in piping systems. These flanges are designed to accommodate the installation of orifice plates, which create a differential pressure that is used to calculate flow rates.

Orifice Weld Neck flanges are available in various sizes ranging from 1/2 inch to 24 inches or larger.

The NPS indicates the nominal size of the pipe that the flange is designed to be used with.

Some Orifice Weld Neck flanges have a raised face that provides a sealing surface for the gasket.

Bolt Hole Size and Spacing:

Bolt holes in the flange are standardized based on the flange size and pressure class.

Proper bolt hole size and spacing ensure compatibility with bolting arrangements for secure attachment to the piping system.

Orifice Weld Neck flanges play a crucial role in orifice metering systems by providing a secure and accurate means of installing orifice plates for precise flow measurement in industrial piping applications.

The flange thickness varies based on the pressure rating and the flange size. The thickness is typically specified in accordance with the pressure-temperature ratings provided by the applicable standard.

• Dimensions are in millimeters, except for bolts and bolt holes.
• Height of Raised Face (RF) in CLASS 300 is 2 mm.
• All other dimensions are in accordance with ASME B16.5.
• Ring joint flanges larger than NPS 3 will require angular meter taps.
