An orifice union flange is a type of flange used in pipeline systems to connect two sections of pipe and provide a means of measuring flow rate. It consists of a flange with a precision-drilled orifice plate located in the center, which creates a constriction in the flow path. This constriction causes a pressure drop that can be measured and used to calculate the flow rate of the fluid passing through the pipe.

The orifice plate is typically made of stainless steel, and the flange can be made from a variety of materials depending on the application. Orifice union flanges are commonly used in industries such as oil and gas, chemical processing, and water treatment.

The orifice union flange provides a simple and cost-effective method of flow measurement, and it can be easily installed and removed for maintenance or inspection. However, it is important to ensure that the orifice plate is properly sized and installed to ensure accurate flow measurement.
