Nominal Pipe Size (NPS) is a North American set of standards used to designate pipe diameter and thickness. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness. 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".
In current practice, pipe size defines with two sets of number 1) Pipe bore/ nominal diameter and 2) Pipe schedule which is nothing but wall thickness of the pipe. The pipe size is specified with two numbers: the nominal pipe diameter (or bore) and the pipe Nominal Bore 1/2 inch (DN 15 mm), Outside Diameter mm. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Nominal pipe size refers to only .
The terms tubing and pipe can often mistakenly be combined with each other causing confusion during the quoting and ordering processes. Please see the. Relation between NPS, NB & OD of a pipe and what is NPT & what are its applications?.
