Weld Neck Flanges
Weld neck flanges are easily identified by their protruding necks. Each flange neck is bored to suit the relevant wall thickness of the piping application on which it is to be used. Weld neck flanges tend to be used in higher pressure applications. Each weld neck has a weld prep at the end of the neck, so that is can be welded directly onto the piping. Once the weld neck is in situ, the pipeline can be blanked off using a blind flange or the bore reduced using a modified flange.
