NPS versus DN
Pipes are idertified by "nominal"o "trade" names that are loosely related to the cctual
dimensions. For instance, a 2-inch galvanized steel pipe hcs 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". The metric designations conform to
International Organization for Standardization (ISO] usage and apply to all plumbing,
nulurul gus, heuling oil, und miscelluneous pipiny used in buildings.
