A neck butt-welding flange has a cone-shaped neck welded to a pipe or cylinder. It’s a strong, one-piece flange that seals better than flat weld flanges. But it uses more materials and costs more to make because it needs forging. It’s suitable for high-pressure, temperature, or strict sealing needs.
