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.
