I need to do some math on some pipe sizes. I may need as many as two
pipes within one, perhaps 3. The center one could be SS, or copper,
as it would have no abrasion on it.

Is there a chart where I would compare a bunch of pipe sizes to pick
out the ones I think may work together? I know there are slight
variations in sizes for all reasons, and will probably have to go to
several sources. It needs to be good steel pipe, corrosion and wear
resistant grades.

According to the CAD drawing I made for my own quick reference, 1-1/2"
pipe slides easily into 2" and 1" fits in 1-1/4" if the welding flash
isn't too thick. The OD of 3/4" and the ID of 1" are almost identical
and in my experience don't fit without lathe work. All other adjacent
sizes from 1/8" to 2" don't telescope. Pipes that differ by two sizes
all do.

The 1:1 drawing of a cross-section of stacked pipe rings shows only
Schedule 40 iron waterpipe from the BigBox stores.

The drawing was done in the 'PADS' PC board design program which
doesn't seem to export properly to other platforms. The free demo
version allows only 30 electrical components, but unlimited line
items.
