Unlike many other kinds of flanges, Long Weld Necks do not have schedule bores. Long Weld Necks, often abbreviated to LWN are typically made with square cuts to replace pipe, not to be welded up to pipe. Schedule bores for regular Long Weld Neck Flanges (Not including Heavy Barrels) are the same as the nominal size of the flange. For example, on a 2 inch LWN, the bore size will also be 2.00 inches.
If you’re inquiring or purchasing a Long Weld Neck from Texas Flange, 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.
