MEASURING THREADED PIPE.
(b) End-To-Center Method.
This measurement is used on a section
of the pipe that has a fitting screwed on one end only. Measure from the
free end of the pipe to the center of the fitting at the other end of the
pipe.
(c) Center-To-Center Method.
This measurement is used when both
ends of a pipe have fittings. Measure from the center of one fitting to the
center of the other fitting at the opposite end of pipe.
(d) Approximate Thread Lengths. The approximate length of thread
on 1/2 and 3/4 inch wrought iron or steel pipe is 3/4 inch. On 1, 1 1/4,
and 1 1/2 inch pipe, it is approximately 1 inch long. On 2 and 2 1/2 inch
pipe, the length of thread is 1 1/8 and 1 1/2 inches respectively.
(e) Determine Pipe Length.
To determine
the
length
of
pipe
required, compute as outlined in 1 through 4 below.
