Weld Neck Flanges
This steel weld neck flanges is circumferential welded into the framework at its neck which implies that the integrity of the butt welded zone can be effortlessly analyzed by radiography. The bores of both pipe and flange match, which diminishes turbulence and erosion inside the pipeline. The weld neck is in this manner favored in basic applications.
Weld neck flanges are flanges made specifically to be butt-welded into a pipe system. There are many specifications for this type of flange. Weld Neck The WN flange is more costly because of its extended neck and the costs involved in connecting it to a pipeline or fitting; yet, it is the preferable choice for high-stress scenarios. Stresses in the pipeline are transferred by the necks, or hubs.
The weld neck flange is significantly reinforced by the progressive change in thickness from the hub base to the wall thickness at the butt weld. The weld-neck flange bore matches the pipeline bore, minimising erosion and turbulence.
