Flat welding flange refers to a kind of flange connected with vessels or pipes by fillet welds. It is an arbitrary flange. According to the integrity of the connection between the flange ring and the straight cylinder section, the design shall be checked according to the integral or loose flange.
There are two kinds of flange rings with and without neck. Compared with the neck butt welding flange, the flat welding flange has simple structure and less materials, but its rigidity and sealing performance are not as good as the neck butt welding flange. Flat welding flanges are widely used in the connection of medium and low pressure vessels and pipelines.
