Where can a buy a 4 ft piece or longer of 4" Orangeburg pipe?

Why?

I need to replace a 4 ft section. I tried ABS but the inside diameter is slightly smaller and it blocked up.

As far as I'm aware it is not available and has not been in production for decades. You would be better off in the long run to replace the entire line with ABS or PVC.
