Orifice Flanges Manufacturer in India
Metalica Forging Inc is an orifice flange manufacturer supplying precision-engineered flanges designed to measure and control flow rates in high-pressure piping systems. Usually, flow nozzles and orifice plates are combined with orifice flanges to provide differential pressure for flow monitoring. In addition to carbon steel, alloy steel (F11, F22) and high-nickel alloys such as Inconel, Monel and Hastelloy, we also manufacture orifice flanges in stainless steel (304, 316, 321).
We support B2B buyers by offering orifice flanges with guaranteed precision, custom tapping arrangements, and ready integration with flow instrumentation. You can choose configurations with jack screw holes, customized bore sizes, and tapped NPT ports based on your process layout. We also provide these flanges in finish-machined or rough-machined condition. Our 2025 update includes downloadable flow guides, MTCs, and CAD-ready drawings for faster procurement. We ship globally and support third-party inspections, making our orifice flanges a trusted choice for accurate and durable flow control across critical industries.
Type of Sub-products
Threaded Orifice Flange
Used in low pressure applications where welding is restricted.
Frequently Asked Questions
What are orifice flanges used for?
Orifice flanges are employed in flow measurement equipment where differential pressure must be created across an orifice plate in order to determine flow rate. Orifice flanges are installed in typical pipelines transferring gas, steam, or liquids in refineries, power generation plants, chemical process units, and water treatment plants. The flanges provide easy accessibility for pressure tap connections and accurate monitoring of flow.
Which standards apply to your orifice flanges?
Our orifice flanges are made in accordance with ASME B16.36 and ASME B16.5 specifications. These specifications state dimensions, face types, pressure ratings, bore sizes, as well as pressure tap location and threading. For high-requirement applications where accuracy is necessary, such the petrochemical, oil and gas, and power industries, this offers compatibility with orifice plates and measurement equipment.
What materials are available for orifice flanges?
We use a wide range of materials to make orifice flanges, including high-performance nickel alloys like Inconel 625, Monel 400, and Hastelloy C276; carbon steel (A105); alloy steel (F11, F22); and stainless steel (304, 316). Material choice based on pressure class, temperature range, and type of fluid. Each material is qualified in terms of corrosion, strength, and temperature rating.
