The ASME/ANSI B16.5 Welding Neck (WN) flange is a high-strength flange designed for use in high-pressure and high-temperature applications. Featuring a long tapered hub, the WN flange is welded directly to the pipe, offering exceptional stress distribution and minimizing mechanical stress at the pipe connection. It is ideal for critical applications in industries such as oil and gas, chemical processing, power generation, y más.
