Orifice Flanges – Manufacturer, Exporter, Supplier & Stockist in India
Vandan Alloys manufactures, supplies, stocks and exports Orifice Flanges designed for piping systems where a flange connection is used with an orifice plate for differential-pressure flow measurement. Our Orifice Flanges are available in different materials, pressure classes, flange facings, sizes and connection configurations according to project requirements.
Based in Mumbai, India, Vandan Alloys serves customers in the oil & gas, refinery, petrochemical, chemical, power generation, process and industrial engineering sectors in India and international markets.
Orifice Flanges – Types We Supply
Vandan Alloys offers Orifice Flanges in different configurations depending on piping design and flow-measurement requirements:
Weld Neck Orifice Flanges
Slip-On Orifice Flanges
Threaded Orifice Flanges
Socket Weld Orifice Flanges
Blind Orifice Flanges
RTJ Orifice Flanges
Raised Face (RF) Orifice Flanges
Flat Face (FF) Orifice Flanges
Custom Orifice Flanges
Drawing-Based Orifice Flanges
The flange configuration, facing, bore, pressure tapping arrangement and dimensions can be selected according to the applicable standard and customer specification.
ASME B16.36 Orifice Flanges
Our Orifice Flanges can be manufactured in accordance with ASME B16.36 for applications involving orifice plate flow measurement.
Orifice flange assemblies generally provide a flange connection for positioning an orifice plate between mating flanges while allowing differential-pressure connections to be taken from the piping system. Pressure tapping arrangements and their locations should be confirmed according to the applicable flow-measurement standard, engineering specification and instrumentation design.
For larger or special-size requirements, dimensional compatibility with the applicable piping flange standard and project specification is reviewed before manufacturing.
Pressure Classes
Vandan Alloys supplies Orifice Flanges in commonly required pressure classes, including:
Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500 and Class 2500
Availability depends on the selected size, flange type, material and applicable dimensional standard.
For high-pressure service, the correct material, flange thickness, facing, bolting arrangement and pressure-temperature rating must be established from the applicable specification.
Materials & Grades
Orifice Flanges can be supplied in a wide range of engineering materials.
Carbon Steel Orifice Flanges
Common carbon steel options include:
ASTM A105 and ASTM A105N
These grades are widely selected for process and general industrial piping where carbon steel is suitable for the operating conditions.
Stainless Steel Orifice Flanges
Stainless steel options include:
ASTM A182 F304, F304L, F316 and F316L
Other stainless steel grades can also be considered depending on corrosion resistance, temperature and process requirements.
Alloy & Special Materials
For demanding applications, Vandan Alloys can supply Orifice Flanges in:
Alloy Steel
Duplex Stainless Steel
Super Duplex Stainless Steel
Nickel Alloys
Monel
Inconel
Incoloy
Hastelloy
Titanium
Material selection depends on pressure, temperature, corrosion conditions and the process medium.
Orifice Flange Facing Options
Different facing configurations are available according to piping design:
Raised Face (RF): Commonly used in process piping and industrial applications.
Flat Face (FF): Used where the piping system and mating equipment require a flat-face connection.
Ring Type Joint (RTJ): Selected for suitable high-pressure and high-temperature services where an RTJ connection is specified.
The flange facing and corresponding gasket arrangement should always match the mating flange and piping specification.
Pressure Tappings
One of the important features of an Orifice Flange assembly is the provision for differential-pressure measurement connections.
Pressure tapping locations and thread details are not treated as a one-size-fits-all feature. Vandan Alloys can manufacture or supply the required arrangement based on the flow-measurement specification, orifice plate design, instrumentation requirement and customer drawing.
This helps maintain compatibility between the flange assembly and the connected differential-pressure instrumentation.
Orifice Flanges for Flow Measurement
Orifice plates are commonly used to create a controlled pressure differential in a piping system. The resulting differential pressure can be used by suitable instrumentation to determine flow.
For this reason, dimensional accuracy is important not only for the flange itself but also for the bore, facing, pressure tapping arrangement and mating connection.
Vandan Alloys can review customer drawings and specifications before production to ensure that the required flange configuration is clearly defined.

Applications
Orifice Flanges are used in piping and flow-measurement systems across several industries, including:
Oil & Gas
Refineries
Petrochemical Plants
Chemical Processing
Power Plants
Gas Processing
Steam Systems
Water & Process Plants
Fertilizer Plants
Industrial Process Piping
Flow Measurement Systems
They are particularly useful where an orifice plate and differential-pressure measurement arrangement form part of the piping system.
Manufacturing & Inspection
At Vandan Alloys, Orifice Flanges are manufactured and inspected according to the applicable product specification and customer requirements.
Depending on the order, inspection may include:
Raw Material Verification
Chemical & Mechanical Test Review
Dimensional Inspection
Bore Verification
Flange Facing Inspection
Pressure Tapping Inspection
Visual Inspection
PMI where specified
Third-Party Inspection
EN 10204 Type 3.1 Material Test Certificate
Special inspection requirements can be discussed before order confirmation.
Custom & Drawing-Based Orifice Flanges
Not every flow-measurement installation uses a standard configuration. Vandan Alloys therefore supports custom Orifice Flanges manufactured according to customer drawings, specifications and project requirements.
Customers can provide flange drawings showing size, class, facing, bore, bolt-hole arrangement, pressure tapping details and other dimensional requirements. Our team can review the drawing before production.
