Weld Neck Flange Materials 

Weld neck flanges are welded directly to the pipe at the neck of the flange. The flange neck has a beveled end that, when connected to a pipe, creates a trough for a strong weld. This flange is desirable for high pressure applications.  These flanges are also knows as Butt Weld Flanges.
