WELD NECK FLANGES also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.
WELD NECK FLANGES are flanges that designed to be jointed to a pipeline by butt welding. The neck, or hub, transmits stresses to the pipeline, reducing stress concentrations at the base of the weld neck flange. The bore of the Weld-Neck flange matches the bore of the pipe, reducing turbulence and erosion.
