What is Orifice Flange

An Orifice Flange is a special flange used to install an orifice plate in a pipeline for flow measurement. The orifice plate creates a pressure difference between the upstream and downstream sides, and the pressure taps on the flange allow instruments to measure this differential pressure.

Compared with standard pipe flanges, orifice flanges include machined pressure tap holes and usually use jack screws to help separate the flange pair during inspection or replacement of the orifice plate.

Orifice flanges are commonly supplied as a pair and used with gaskets, bolts, nuts, orifice plates, and flow measurement instruments.

Orifice Flange Materials & Grades

Orifice flanges are available in different materials according to working medium, pressure, temperature, corrosion environment, and project standard.

Carbon steel orifice flanges are commonly used in oil, gas, steam, and general industrial pipelines. Stainless steel orifice flanges are suitable for chemical, food, pharmaceutical, and corrosive media. Alloy steel materials are suitable for high-temperature and high-pressure systems.

Orifice Flange Dimensions

Orifice Flange Dimension Drawing

Orifice flanges can be manufactured according to standard dimensions or customer drawings. Key dimensions include outside diameter, bore size, flange thickness, bolt circle diameter, bolt hole diameter, pressure tap position, jack screw hole, and sealing face type.

Advantages of Orifice Flange

Accurate Flow Measurement

Orifice flanges are designed for differential pressure flow measurement and provide reliable connection for orifice plate systems.

Integrated Pressure Taps

Machined pressure tapping holes allow easy connection with flow meters and differential pressure instruments.

Easy Inspection and Maintenance

Jack screws help separate the flange pair, making it easier to inspect, clean, or replace the orifice plate.

Multiple Type Options

Weld neck, slip on, threaded, RF, FF, and RTJ types can be supplied according to different pipeline requirements.

Reliable Sealing Performance

Accurate machining and proper gasket sealing help reduce leakage risk in flow measurement systems.

Custom Manufacturing Available

Bore size, tap position, material, face type, pressure rating, and accessories can be customized according to project drawings.

FAQ

Q: What is an Orifice Flange?

A: An orifice flange is a special flange used with an orifice plate for flow measurement in pipeline systems.

Q: What standard is commonly used for Orifice Flange?

A: ASME B16.36 is the common standard for orifice flanges. ASME B16.5 and custom drawings can also be used for customized requirements.

Q: What is the function of pressure taps?

A: Pressure taps allow instruments to measure the pressure difference before and after the orifice plate, which is used to calculate flow rate.

Q: Why do Orifice Flanges use jack screws?

A: Jack screws help separate the flange pair during maintenance, making it easier to remove or replace the orifice plate.

Q: Can you supply Orifice Flange with accessories?

A: Yes. Orifice plates, jack screws, bolts, nuts, gaskets, and customized accessories can be supplied together.
