### What is the Formula for pipe fitting take off for 45degree fittings?

There is no one formula for fitting take offs. The general rule
used for gal and black malleable fittings is on a center to center
measurement to take off the ID of the pipe you are using on each
end of the pipe. Example if center to center measurement is 10 feet
between a 1 inch tee and a 1 inch 90 ell. The end to end
measurement would be minus 2 inches for a total of 9 foot 10
inches. If you are a industrial pipe fitter there is a pipe fitters
blue book that covers all this and a lot more,but the formula we
use is take the size of the fitting and break it down 4 times add
the second and forth dimension together and there's your take
off,ex. 10 inch 45 degree carbon steel would be like this,,,,,10-5-
2.5-11/4=6 1/4 take out.......
