Introduction Of Flat Welded Flange

Flat welded flange is a kind of flange connected with fillet weld of container or pipeline. It belongs to arbitrary flange. According to the integrality of the connection between the flange ring and the straight tube section, the integral flange or the loose flange are checked separately in the design. There are two kinds of flange rings with neck and without neck. Compared with the butt-welded flange with neck, the flat-welded flange has simple structure and less material consumption, but its stiffness and sealing performance are not as good as that of the butt-welded flange with neck. Flat welded flanges are widely used in connection of medium and low pressure vessels and pipes.
