It is normal to bend a material about the center-line or neutral axis, as the neutral axis is used to calculate the length of the pipe before bending. To design the part based on knowing the desired outside diameter and the pipe diameter, use this to calculate the center-line diameter. The most common method of modeling the bent pipe would be to sweep the pipe cross section along a path defined by the neutral dia. of the bend.
