Calculate Take-Out and

Butt Weld Elbow Cut Marks

The Take-Out function can be used to quickly

solve a Take-Out and butt weld elbow cut

marks for a known bend angle and Pipe Size.

Find the arc lengths for an odd bend angle of

37° for 12” pipe.

The cut length for the pipe is 35 and 1/4

inches and bend angle is 40.46°. Included

in the outputs are the arc lengths to be used

to cut your butt weld elbow to the calculated

bend angle. These are inner arc length of 4

and 1/32 inches, center arc length of 6 and

11/32 inches, and outer arc length of 8 and

11/16 inches.

Concentric Pipe Bend Cutback

Find the pipe Cutback when you are running

pipes through a 45º bend with a 10" offset.
