What do you mean by Nominal Pipe Size?

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.

When did Nominal Pipe Size replace wall thickness?

In March 1927, the American Standards Association surveyed industry and created a system that designated wall thicknesses based on smaller steps between sizes. The designation known as nominal pipe size replaced iron pipe size, and the term schedule ( SCH) was invented to specify the nominal wall thickness of pipe.

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. Steel pipe sizes around the world are standardized on historic dimensions that are now referred to as Nominal Pipe Sizes (NPS).

How big is a 2 inch plumbing pipe?

Pipes are identified by “nominal” or “trade” names that are loosely related to the actual dimensions. 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”.
