Assuming the "curves" in your drawing are arcs,  the length of the straight line in your drawing is:

 

L = 2 * Sqrt( rc^2 - ri^2)

 

where rc = radius of center line arc, ri = radius of inside curve

 

This ignores the diameter  of the pipe.  To include the pipe diameter use:

 

L = 2 * sqrt(rc^2 - (ri + diaPipe/2)^2)

 

where diaPipe is pipe diameter
