The welding neck flange is normally referred to as the "high hub" Flange. It is designed
To transfer stresses to the pipe, thereby reducing high stress concentrations
At the base of the Flange. The welding neck flange is the best designed butt-welded
Flange of those currently available because of its inherent structural
Value. It is expensive because of the design.
