Orifice Flanges

C-Way Engineering Exports is one of the most professional orifice flanges manufacturers, suppliers, and exporters in India, we are featured by high-quality products and competitive prices. We produce international standards ASME/ANSI/IS/DIN/BS/JIS orifice flanges. Standard sizes of carbon steel and stainless steel orifice flanges are readily available in the stock to deliver immediately.

Orifice flanges are specialized flanges designed for use with orifice meters to measure the flow rate of fluids in piping systems. They provide a means of installing orifice plates or other flow measurement devices directly into the pipeline while also providing access for maintenance or replacement. Orifice flanges are commonly used in industries such as oil and gas, petrochemical, chemical processing, and water treatment.

Orifice flanges consist of a standard flange with additional features to accommodate the installation of an orifice plate or flow measurement device. They typically have smaller bore or tapped holes on one side of the flange where the orifice plate is installed. The orifice plate is positioned between the two flanges, creating a constriction in the flow path that allows for accurate measurement of fluid flow rate.

Orifice flanges can have either a raised face (RF) or ring-type joint (RTJ) facing to provide a sealing surface for gaskets. The flanges are available in various pressure ratings, sizes, materials, and facing configurations to suit different application requirements.

All Flanges with standard sizes and materials are readily available in stock for immediate delivery. "Looking for large diameter Flanges ? Contact us today for Customized Flanges.

Applications of Orifice Flanges

Oil and Gas Industry: They are used in oil and gas production facilities, refineries, pipelines, and distribution networks for flow measurement and control of hydrocarbons and other fluids.

Petrochemical Plants: Orifice Flanges find application in petrochemical plants for measuring and monitoring the flow of chemical fluids in process piping systems.

Chemical Processing: They are employed in chemical processing plants for flow measurement and control of corrosive fluids, acids, and solvents.

Water Treatment: Orifice Flanges are used in water treatment plants, desalination facilities, and distribution networks for measuring and monitoring the flow of water and wastewater.

Power Generation: They find applications in power generation facilities for flow measurement and control of steam, condensate, and cooling water in boiler systems and power plants.

Advantages of Orifice Flange

Accurate Flow Measurement: Orifice Flanges provide a reliable and cost-effective method for measuring fluid flow rate in piping systems. Versatility: They can accommodate various types of orifice plates, flow measurement devices, and accessories to meet specific application requirements. Access for Maintenance: Orifice Flanges allow for easy access to the orifice plate for maintenance, inspection, or replacement without the need to disassemble the entire piping system. Compatibility: They are compatible with standard flanges, valves, and fittings, allowing for seamless integration into existing piping systems.
