Q

Piping cross-sections over 12 inches in diameter are sized by the __________.

🔍 Key Concepts

• How pipe sizes are traditionally specified in marine and industrial piping systems • The difference between inside diameter, outside diameter, and wall thickness when describing pipes • How large-diameter pipes (over about 12 inches) are commonly identified in engineering standards

💭 Think About

• When engineers or naval architects order large pipe, which dimension do they most often quote to the supplier? • Which measurement is easiest to verify quickly with a tape measure on an installed large pipe? • Think about how changes in wall thickness would affect inside vs. outside measurements— which one stays more consistent for size designation?

✅ Before You Answer

• Be clear on what is meant by cross-section over 12 inches in diameter—is this referring to nominal pipe size or an actual measured dimension? • Compare how a change in wall thickness would affect the inside diameter versus the outside diameter label • Eliminate any answer choices that are rarely (or never) used as the primary way to name or specify pipe size in practice
