Large radius bending of pipe, tube, angle, channel, flat bar, and T-shapes is usually done on a pyramid style 3 roll bender. When rolling pipe or tube, you will need the 3 rolls to match the contour of the tube to prevent the wall stress from flattening the tube. One die set can roll parts to different radii.
Besides standard values for tool design the VDI guideline 3389 offers a formula for the calculation of the length of unfolding. The effective length for an angle of 90 degrees is, thus, calculated on the basis of the length of the two inner sides and an add-up value of x .
