Summary

Nominal Pipe Size (NPS) is a defined set of standard pipe sizes commonly used for process piping. NPS piping is defined in terms of a nominal diameter and wall thickness (defined by the pipe schedule). This article provides characteristics for NPS piping in Imperial units.

Definitions


$\text{OD}$	Outer diameter (in)
$\text{ID}$	Inner diameter (in)
$\text{WT}$	Wall thickness (in)
$\text{ICSA}$	Inner cross sectional area (in^2)
$\text{ECSA}$	External cross sectional area (in^2)

NPS Pipe Characteristics in Imperial Units

The characteristics of NPS piping in Imperial units are listed in the tables below. For the following tables in metric units please refer to here
