[Shop-talk] Compressed Air Lines, RapidAir

[Arvid Jedlicka]

I won't be much help there. I have a "radiator" on the compressor so a lot 
of the cooling and condensing gets done in the tank. Then there is a 
desiccant dryer between the tank and the plumbing so it is pretty dry going 
into the copper.

I thought the reason for black iron was the condensing capability of the
pipe, no?

Like you, I think that the threading, cutting, and sealing issues with
black iron are a huge pita, and copper is comparatively cake to
install.  But if black iron is that much better at keeping the air dry,
well, I'm only going to do this once...

What say the list?  Am I overstating the benefits of iron?  Something
else to think about is that copper won't rust on the inside.  There's
that...
