In the joint band example for a 60" pipe, what is the stated pipe diameter?

• A. 48 inches
• B. 60 inches
• C. 72 inches
• D. 96 inches

Answer: (B)

The key idea is that the diameter you use for sizing the joint band comes from the pipe’s stated (nominal) size given in the scenario. If the problem describes a 60-inch pipe, the diameter to use in calculations and for selecting the joint band is 60 inches. This value is the size referenced in the setup, and fittings like joint bands are chosen to match that stated diameter. In practice, the nominal size is the label you see on plans and specs, though the actual outside diameter can vary with wall thickness and schedule; for this question, the given description pins the diameter at 60 inches. The other numbers would correspond to different pipe sizes and don’t match the described case.
