🔍 Key Concepts

• Pipe schedules in marine piping systems • Relationship between pipe size, pressure rating, and wall dimensions • Common standards used for pipe and fittings (e.g., Schedule 40 vs Schedule 80)

💭 Think About

• When a pipe is labeled 'Schedule 40' or 'Schedule 80', what physical characteristic of the pipe is changing? • How does this schedule number affect the pipe’s ability to handle internal pressure without failing? • Which of the choices refers to a dimensional property of the pipe itself rather than a property of the material?

✅ Before You Answer

• Identify which choices describe material properties (like strength) versus dimensional properties (like size or thickness). • Recall that higher schedule numbers generally mean the pipe is heavier duty and used for higher pressure—what part of the pipe changes to achieve that? • Confirm that the term is used primarily with pipe and pipe fittings, not with plate, tubing, or bolts.
