Thanks for the info Aaron, it is interesting. Maybe others that work in
specialized piping are willing to share info (within reason and not
disclosing proprietary stuff, of course) with those of us engaged in the
more common fields.
<a href="http://www.seiberling4cip.com/evol&dev.htm">http://www.seiberling4cip.com/evol&dev.htm</a> (which I have linked from <a href="http://www.pipingdesign.com/steamtraps.html">http://www.pipingdesign.com/steamtraps.html</a>) seems to be a pretty good overview of CIP.
