The "official" outer diameter of anything that is 1 1/2 inch
iron pipe size is 1.900 inches. 2 1/8 tubing with .058
wall fits over this with a .0545 inch gap (at least
theoretically).
What I do is use 2 inch irrigation tubing and put it
on the INSIDE of 2 inch PVC sch 40 pipe. The inner
diameter of this pipe is about 2.060 inches, resulting
in a .030 inch gap. I then use U-clamps designed
for 2 inch iron pipe size to clamp the PVC to a 4x4
or whatever.
In practice, there are enough irregularities in the
PVC such that you need fairly large gaps like this
to be able to typically slide the pieces together.
