Question 1 of 27070

When renewing sections of pipe in a hydraulic system, the nominal pipe size of the piping always indicates the __________.

🔍 Key Concepts

• Nominal pipe size (NPS) and what 'nominal' means in piping • Difference between inside diameter, outside diameter, and wall thickness • How threaded connections on standard pipe are sized in practice

💭 Think About

• Think about whether 'nominal' means an exact measured dimension or a standard reference size. • When a mechanic asks for '1-inch pipe' at a supply house, which dimension are they really referring to—ID, OD, wall thickness, or the size that matches standard threads? • Consider how using the wrong interpretation of pipe size could cause fittings or threaded connections not to match.

✅ Before You Answer

• Verify what NPS (Nominal Pipe Size) actually represents in pipe standards. • Check whether the measured inside diameter of pipe exactly equals the nominal size for all schedules (wall thicknesses). • Confirm how standard threaded fittings are labeled and what dimension those labels correspond to.
