Question

to calculate the end-to-end dimension of a pipe when you know the end-to-center measurement, subtract ______. a. the end-to-center measurement b. the face-to-face measurement c. the thread makeup d. one fitting allowance

Explanation:

In pipe fitting, the end-to-center measurement includes the length from the pipe end to the fitting's center plus a fitting allowance (the part of the fitting that inserts into the pipe). To get the end-to-end dimension (total length of pipe needed between two ends), you subtract one fitting allowance from the end-to-center measurement.

Answer:

D. one fitting allowance
