ANSI B16.47 Series B Welding Neck Flange

Design and Purpose:

The Series B Welding Neck Flange is a crucial component in piping systems.
It is designed to connect pipes, valves, and other equipment in a pipeline, providing a strong, leak-resistant joint.
Unlike other flanges, it features a welding neck that gradually transitions from the flange face to the pipe, enhancing stress transfer and handling temperature and pressure variations effectively 1.
