🔍 Key Concepts

• Nominal pipe size (NPS) in U.S. piping systems • Difference between inside diameter (ID), outside diameter (OD), and wall thickness/schedule • How small versus large pipe sizes are commonly designated in marine piping

💭 Think About

• For pipe sizes from 1/8 inch up through common shipboard sizes, what does the nominal size usually correspond most closely to: the actual ID, the OD, or something derived from both? • Think about how two pipes of the same nominal size but different schedules (wall thicknesses) are described. Does the nominal value change with wall thickness? Why or why not? • When you look at standard pipe charts, which dimension stays tied to the nominal size, and which one varies with the schedule?

✅ Before You Answer

• Verify how nominal size is defined in standard pipe tables (e.g., NPS and schedule charts). • Check whether the nominal dimension changes when wall thickness changes for a given size. • Confirm whether options mentioning a range like "from 1/8 inch to 12 inches" are describing a method of sizing or just a set of sizes.
