Brief: Welding Neck Flanges (WN) are one of the most popular flange types used in high-pressure and high-temperature applications. Designed in accordance with ANSI/ASME B16.5 standards, these flanges feature a long tapered hub that provides excellent stress distribution through the weld neck. They are commonly used in critical pipeline systems for oil & gas, petrochemical, power plants, and fire protection industries.
