Piping cross-sections ranging from 1/8 inch to 12 inches in diameter, are sized by __________.

Question 1 of 27070

Piping cross-sections ranging from 1/8 inch to 12 inches in diameter, are sized by __________.

🔍 Key Concepts

• Nominal pipe size (NPS) system used in marine piping • Difference between inside diameter (ID), outside diameter (OD), and threaded diameter • How small-bore pipe (1/8" to 12") is commonly specified in standards

💭 Think About

• Think about how pipe sizes are listed in catalogs: when you order a 2-inch pipe, which dimension is that 2 inches actually referring to? • Consider whether pipe wall thickness changes the stated size in the designation system for these pipe sizes. • Ask yourself: for threaded pipe, is the stated size measured over the threads, or is it a standard reference size that stays the same even if schedules change?

✅ Before You Answer

• Verify how nominal pipe size (NPS) is defined in standard piping practice for sizes 1/8" through 12" • Check whether changes in wall thickness (schedule) change the named size or just the actual inside diameter • Confirm whether the dimension used to "size" the pipe is the real measured diameter or a conventional/nominal value
