NPS (Nominal Pipe Size) Guide: Dimensions, Charts Specifications For instance, a 2-inch galvanized steel pipe has an inside diameter of about 2 1 8 inches and an outside diameter of about 2 5 8 inches In plumbing pipe size is referred to as nominal pipe size - NPS, or "Nominal Pipe Size" The metric equivalent is called DN or "diametre nominel"
Nominal Pipe Size NPS, Nominal Bore NB, Outside Diameter OD OD is the outside diameter of the pipe and is fixed for a given size The NPS is very loosely related to the inside diameter in inches, but only for NPS 1 8 to NPS 12 For NPS 14 and larger, the NPS is equal to the outside diameter (OD) in inches
