Hi. A newbie sort of question he I want to clamp a sort section of
2" pipe vertically to my milling table, and then use a boring bar set
to increase it's ID a tad. (I don't have access to a lathe.) How do
I clamp it? Do they make some sort of chuck for this purpose? What
is it called and where do I get one? If it makes a difference, I
have an RF45 clone bench mill and a import 8" rotary table.

You obviously ARE a newbie - You got a lotta nerve starting a topic on
MetalWorking!

ahem.

Most people with rotary tables have a lathe chuck to fit it.
That would be the ticket in this case.

Big vee-block would be easiest

Otherwise, U-bolt it to a slotted angle plate. You would have to make
sure it clamps vertical in the 2nd plane.

If you have 2-4-6 blacks you could bolt them together at right angles to
make a Vee-block.

Vise and a pair of V-blocks?

--If you can move the head of the mill to somewhere other than the
top of the table you're golden. Clamp pipe to side of table, move head and
go for it. There's a very neat widget called a Verti Vise but it ain't
cheap..

How sort is it? If only a few inches you could clamp it in the vise
between two vee blocks, or one and a piece of wood. Two blocks will
distort the pipe less. A diagonally braced cast iron angle plate is
likely the cheapest useful fixture you could buy for this and later
jobs.

I prefer this type for precision work:

By laying it on its side round and square parts can be held precisely
upright in the inner corner.

I've never thought of that. I wish someone that knows the many uses of 1-2-3 and 2-4-6
blocks would give a dissertation on their creative use.
