NPS stands for which term?

• A. Nominal Pipe Size
• B. National Pipe Standard
• C. Normal Pressure Section
• D. Nipple Pipe Size

Answer: (A)

Nominal Pipe Size is the designation used in piping to size pipes in North America. The term “nominal” means it’s a conventional, approximate size chosen to standardize fittings and connections, not the exact inner or outer measurements. For a given nominal size, the outside diameter is fixed, while the inside diameter depends on the pipe’s wall thickness (schedule). That standardization lets different components—pipes, valves, and fittings—to match up reliably. The other phrases aren’t recognized terms for this sizing system, so they don’t fit.
