It should be noted that some intermediate standard pipe sizes are available commercially, such as 5 inch (125 mm), however these are less common. For pipe sizes with a NB of 14 inch (DN 350 mm) and above, the nominal bore is the same as the pipe Outside Diameter (OD).Confusingly, for pipe sizes with a NB of 12 inch (DN 300 mm) and below, the nominal bore and outside diameter are different.For example, a pipe with a 12 inch NB (DN 300 mm) has an OD of 12.75 inches, or 324 mm.

But like wood 2-by-4′s, which are not really 2 inches by 4 inches, pipe is identified by “nominal” or “trade” names that are related only loosely to 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.It is called “2-inch pipe” only for the sake of convenience.Since few, in any, pipe products have actual dimensions that are in even, round inch-pound numbers, there is no need to convert them to even, round metric numbers. Instead, only their names change – from inch-pound to metric.Pipe cross sectional sizes do not change.t is called “2-inch pipe” only for the sake of convenience. Since few, in any, pipe products have actual dimensions that are in even, round inch-pound numbers, there is no need to convert them to even, round metric numbers.

For example, NPS 14 Sch 40 has an OD of 14 inches and a wall thickness of 0.437 inches. However the NPS and OD values are not always equal, which can create confusion. 1  For NPS ⅛ to 12 inches, the NPS and OD values are different.2  For example, the OD of an NPS 12 pipe is actually 12.75 inches. For NPS 14 inches and up, the NPS and OD values are equal. 2  In other words, an NPS 14 pipe is actually 14 inches OD.

As the schedule is increased, so does the wall thickness. At a pipe schedule of 160, a 12 inch NB pipe has a wall thickness of 1.312 inches (33.3 mm). It should be noted that not all pipe schedules are available for all pipe sizes.t should be noted that some intermediate standard pipe sizes are available commercially, such as 5 inch (125 mm), however these are less common. For pipe sizes with a NB of 14 inch (DN 350 mm) and above, the nominal bore is the same as the pipe Outside Diameter (OD).

1 For example, the OD of an NPS 12 pipe is actually 12.75 inches. 2  To find the actual OD for each NPS value, refer to the tables below. ( 3 Note that for tubing, the size is always the actual OD.). 4  For NPS 14 inches and up, the NPS and OD values are equal. For NPS 14 inches and up, the NPS and OD values are equal. 2  In other words, an NPS 14 pipe is actually 14 inches OD.

This then sets the outside pipe diameter, the wall thickness (and hence the internal diameter). A list of common standard pipe sizes are given below.
