Orifice Flanges – Manufacturer & Supplier in India
What are Orifice Flanges?
Orifice Flanges are a specialized type of flange used in flow measurement applications. These flanges are designed to hold orifice plates, which help measure the rate of fluid or gas flow in pipelines. Orifice flanges include jack screws to separate the flanges for easy inspection or replacement of the orifice plate.
These flanges are widely used in industries like oil & gas, petrochemical, water treatment, and power generation, where accurate flow measurement is crucial.
Key Features of Orifice Flanges
Flow Measurement – Designed to accommodate orifice plates for precise flow monitoring.
Integrated Jack Screws – Allow easy plate removal and maintenance.
Available in Various Materials – Stainless Steel, Carbon Steel, and Alloy Steel.
Multiple Pressure Ratings – Available in Class 150 to Class 2500.
Compatible with Different Pipeline Systems – Used in gas, liquid, and steam applications.
Types of Orifice Flanges
Orifice flanges come in different types based on their pressure rating and connection type:
- Weld Neck Orifice Flange
Used in high-pressure and high-temperature environments.
- Slip-On Orifice Flange
Suitable for low-pressure applications, offering easy installation.
- Threaded Orifice Flange
Ideal for applications where welding is not feasible.
- Blind Orifice Flange
Used to completely block flow in a pipeline system.
- RTJ (Ring Type Joint) Orifice Flange
Provides leak-proof sealing for high-pressure applications.
