Q

An American Standard Tapered pipe thread has a taper of __________.

🔍 Key Concepts

• American Standard Taper Pipe Thread (NPT) proportions • Relationship between taper per foot and taper per inch • How taper is measured on the diameter versus the radius

💭 Think About

• Think about how much the diameter of the pipe thread changes over a 12-inch (1-foot) length. • Convert the standard taper from change per inch to change per foot to match the answer choices. • Consider whether the taper is specified on the diameter (full width) or just on one side (radius) of the thread.

✅ Before You Answer

• Recall the standard NPT taper often given as a change in diameter per inch of length and multiply by 12 for per-foot value. • Verify whether the taper value you remember applies to diameter, not radius — that will double the amount if you confuse them. • Check that the numerical value you choose is consistent with a relatively slight taper, not something that would appear very steep on a short fitting.
