The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.
1-13/16"= The tangent of half the degree X the radius of the elbow.
Measure to the center of the Ell and decuct for the threads ..

Short Radius 90 degree elbows are the same as pipe size.... Long Radius 90's are pipe size times 1.5.... so a 6" (SR) elbow is 6"... a 6" (LR) elbow would be 9"

90 degree angle rolled on a 45
In the area of industrial pipe fittings: Long radius 90 deg elbow has a take off dimension of one and one half times the nominal diameter of the pipe. Ex-4 inch pipe has an actual diameter of 4.5, for the elbow the take off dimension would be 4"*1.5=6". The short radius elbow take off dimension is the same as the nominal size, 4". To add to the point, a short radius elbow can be used typically where space is a constraint. Hence fluid flow is also restricted in this case unlike in case using of Long Elbow.
