Orifice Flanges are typically found in piping systems to measure and manage the flow rate of liquids, gases, or steam. They are used in the oil or gas, petrochemical, power generation, chemical processing, and water treatment industries. Their purpose is to secure an orifice plate in between sections of pipe to enable accurate measurement of flow and pressure. Common applications are flow meters, process control, and energy management systems. Orifice Flanges are critical components in industrial flow measurement equipment due to their durable construction, corrosion resistance, and suitability for operation with a range of pressure ratings.
