Long weld neck flanges do NOT have scheduled bores!



Just a friendly reminder to everyone that long weld neck flanges and their variants do not have schedule bores. These flanges are typically made with square cut ends to replace pipe, not to be used as flanges to weld up to pipe. You may request any wall thickness and additional custom weld bevel you would like, but the standard for these flanges is defined per the dimensions in our catalog. The actual bore size for regular long weld neck flanges (NOT heavy barrels) is the same as the nominal size of the flange. So for example, on a two inch long weld neck flange, the bore size is 2.00 inches.
