As Paul says, "Pipe" is for conveying fluids such liquids and gases, mostly
under pressure. You have different "schedules" of pipe, meaning different wall
thickness for different pressures. The steel used is not what you need for high
mechanical strength.

What you need is "Mechanical Tubing". It may look like a pipe to a layman, but
it has different specifications and is described under different ASME codes.
"Tubing" can be supplied drawn, (DOM). It has usually even OD dimensions and
wall thickness in fractions of inches (1/16" for wall and coarser for OD).

Just learn the terminology. There is pipe for fluids, and there is "TUBING",
which is what you need.
(Piping is only used by plumbers).

For rough tube sizes see message of August 4, 03.

I finally figured that out when I read Pauls "once again"... :)

    I have too many basic questions..... it's not fair (or right) for me
to slam Pauls newsletter with off topic questions. I've learned a lot
about the rotary here, and I want to keep it that way. :)

   And... thank you guys for "learnin' " me the difference between
"pipe" and "tube".  :)

   back to lurk mode.
