Orifice Flanges Supplier
Flanges Built Around Flow Measurement
Sohum Industrial Sales Corporation supplies Orifice Flanges for industrial flow-measurement and process-piping applications across West Bengal, Kolkata, Odisha, Chhattisgarh, Bihar, Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura and Bhutan.
Unlike ordinary pipe-joining flanges, an Orifice Flange is specifically designed to accommodate an orifice plate used for differential-pressure flow measurement. The flange assembly provides provisions for pressure tapping, allowing the pressure difference across the orifice plate to be measured and converted into flow information.
What an Orifice Flange Actually Does
When fluid passes through an orifice plate, its flow area is deliberately reduced. This creates a measurable pressure difference between the upstream and downstream sides of the plate. Orifice Flanges are engineered to provide convenient connections for these pressure measurements. They are therefore an important component in metering arrangements used in process industries, utilities and fluid-handling systems.

Pressure Tapping Arrangement Matters
The pressure-tapping holes are one of the defining characteristics of an Orifice Flange. Their location affects how upstream and downstream pressure are sensed.
Depending on the application and applicable measurement standard, different tapping arrangements may be used. The correct arrangement should therefore be specified by the instrumentation or process-design team rather than selected solely on flange size.
Material Options for Process Environments
Carbon Steel
A commonly selected option for general industrial and utility service where the operating environment permits its use.
Stainless Steel
Useful for applications where improved resistance to corrosion or process-fluid exposure is required.
Alloy Steel
Considered for specialized services involving elevated temperature or demanding mechanical conditions.
Material selection should account for the process medium, operating temperature, pressure and corrosion conditions.
Where Orifice Flanges Are Commonly Installed
Orifice Flanges are widely associated with flow-measurement systems in:
- Oil and gas processing
- Refineries
- Petrochemical plants
- Chemical manufacturing
- Power generation
- Steam distribution
- Water-treatment facilities
- Compressed-gas systems
- Process industries
- Industrial utility networks
They can be used for measuring the flow of liquids, gases and steam when the overall metering system is designed appropriately.
Engineering Points to Check Before Ordering
An Orifice Flange should be specified as part of the complete measurement arrangement. Buyers and engineers should consider:
- Pipe nominal diameter
- Pipe schedule
- Fluid type
- Operating pressure
- Operating temperature
- Differential-pressure range
- Orifice plate bore
- Pressure-tapping arrangement
- Flange material
- Pressure class
- Facing type
- Applicable flow-measurement standard
Correct coordination between the flange, orifice plate, gasket, bolts and differential-pressure instrumentation is essential for reliable measurement.
