The ASME/ANSI B16.36 Orifice Welding Neck (WN) flange is a specialized flange designed for precise flow measurement in piping systems. It includes a bored center to accommodate an orifice plate, which measures the flow rate of fluids, gases, or steam. The welding neck design provides a secure connection and optimal stress distribution, making it ideal for high-pressure and high-temperature applications in industries such as oil and gas, chemical processing, and power generation.
