Orifice Flanges
Orifice flanges are specialized types of flanges used in piping systems to facilitate the installation of orifice meters or other flow measurement instruments. They have features such as a concentric or eccentric hole that matches the size of the orifice plate used for flow measurement. These flanges allow easy access to the orifice plate for inspection, replacement, or adjustment without disturbing the rest of the piping system
Key Features of Orifice Flanges
- Orifice Bore : Orifice flanges are designed with a precisely machined bore that matches the diameter of the orifice plate used for flow measurement. This ensures accurate measurement of fluid flow rates.
- Concentric or Eccentric Design : Orifice flanges may come in either concentric or eccentric designs, depending on the requirements of the application. Concentric designs have the orifice hole centered within the flange bore, while eccentric designs have the orifice hole offset from the center.
- Pressure Tappings : Orifice flanges typically have pressure tappings for connecting pressure sensors or gauges to measure upstream and downstream pressures, which are essential for calculating fluid flow rates accurately.
- Material Compatibility : They are available in a variety of materials, including carbon steel, stainless steel, Exotic steel and alloys, to suit the specific requirements of the application and to withstand the corrosive effects of the fluid being measured.
- Accessibility : Orifice flanges are designed to allow easy access to the orifice plate for inspection, maintenance, or replacement without needing to disassemble the entire piping system.
- Sealing : They feature sealing surfaces, such as raised faces or ring-type joints, to ensure leak-tight connections between flange components and prevent fluid leakage.
- Sizes and Pressure Ratings : Orifice flanges are available in a wide range of sizes and pressure ratings to accommodate various flow rates and operating conditions.
- Corrosion Resistance : Orifice flanges may be coated or treated to enhance corrosion resistance, particularly in applications involving corrosive fluids or harsh operating environments
