ASME B16.5 Oiled Surface Long Weld Neck Flange Non Alloy

ASME B16.5 Long Weld Necks Flange

Long Weld Necks(LWN), also commonly referred to as Nozzles, typically are made with square cuts to replace pipe, not to be welded up to pipe. Due to this, long weld necks do not have schedule bores. A typical weld neck flange has a weld prep at the tip of the neck to weld up to matching pipe, whereas long weld neck flanges, or “nozzles,” are square cut at the ends for the purpose of utilization with your tank or alternate assembly. 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.
