Stainless steel orifice flanges are a type of flange that is used to measure the flow of fluid through pipelines. They are used in industrial applications where precise flow control and measurement is important. The orifice flange consists of a flange with a concentric hole, or orifice, that is drilled through the center. The orifice is designed to create a pressure drop in the fluid flow, which can be measured to determine the flow rate of the fluid. The flange itself is made of stainless steel, which makes it resistant to corrosion and highly durable.
Stainless steel orifice flanges are typically used in oil and gas, chemical processing, and petrochemical industries, where they are used to measure flow rates in pipelines carrying fluids such as crude oil, natural gas, and hydrogen. They are also used in water treatment facilities to measure the flow rate of water and other fluids.
The advantages of using stainless steel orifice flanges include their resistance to corrosion and their durability. Stainless steel is also an excellent choice for food and beverage processing industries, as it is easy to clean and does not impart any taste or odor to the fluids flowing through the pipeline.
In summary, stainless steel orifice flanges are an important type of flange used for flow control and measurement in industrial applications, offering high durability, corrosion resistance, and ease of cleaning.

Orifice Flanges Types
There are several different types of orifice flanges available on the market today, each designed for specific applications and purposes. The most common type is a lap joint flange which consists of two pieces that fit together via bolts or screws. Another popular type is a threaded or socket-welded flange which connects pipes together with screws instead of bolts. Finally, there is also a blind flange that covers openings in pipes without actually connecting them together.
Advantages of Orifice Flanges
- The Orifice is small plates and easy to install/remove.
- Offer very little pressure drop from which 60% to 65% is recovered.
- The orifice meter can be easily maintained.
- Measures a wide range of flows.
- They have a simple construction.
- They have easily fitted between the flanges.
- They are the most suitable for most gases and liquids.
- They are cheap, The price does not increase dramatically with size.
