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.
