Carbon Steel Orifice Flange

Carbon Steel Orifice Flanges are used in conjunction with orifice meters to measure the flow of liquids, gases, and steam in pipelines. These flanges are designed with orifice plates and jack screws, which allow easy removal and maintenance. They are commonly used in industries such as oil & gas, chemical processing, power plants, and water treatment.
