What Is a Weld Neck Flange?

Welded flanges are parts that connect the pipe to the pipe and are connected to the pipe end. There are holes in the welding flange, and the two flanges are tightly connected by bolts. Sealed with gasket. Welded flanges are a disk-like part that is most common in pipeline engineering.
