An Orifice Weld Neck Flange is a precision-engineered component designed for accurate flow measurement in pipelines. It features a specially machined bore that accommodates an orifice plate, enabling the precise monitoring and control of fluid or gas flow rates within a system. The flange’s weld neck design provides superior strength and ensures smooth stress distribution between the flange and the connected pipe, making it ideal for high-pressure and high-temperature applications. Manufactured from premium materials such as carbon steel, stainless steel, or alloy steel, these flanges offer excellent corrosion resistance and long-term durability. They are widely used in industries such as oil and gas, petrochemical, power generation, and water treatment, where accuracy, safety, and efficiency are critical. Available in various sizes and pressure classes, orifice weld neck flanges are essential components for reliable flow measurement and process control.
