It is just a simple case of mathematics.

If you are using long radius (LR) elbows: 6000mm minus the center to end of both LR elbows. The center to end of a LR ELL is 1.5 times the nominal diameter.

If you are using short radius (SR) elbows: 6000mm minus the center to end of both SR elbows. The center to end of a SR ELL is 1.0 times the nominal diameter.
