The Welding Neck Flanges are also called "high hub" flange. Their design is specialized and is made for transferring various stresses onto the pipe. Unique design of this products increases its cost. This is beneficial in minimizing the high stress concentrations at flange's base. Actually, the welding neck flange can be called the improved and efficient version of butt-welded flange, mainly because of its inherent structural value. The main use of these flanges is in heat coupling of pipes, wherein there is a chance that section can be expanded due to the extra bending stress.
