The only effect wind chill has on inanimate objects, \such as water pipes,
is to more quickly cool the pipe to the current air temperature.
Object will NOT cool below the actual air temperature due to alleged wind chill!@
that occurs on living flesh.

A friend came over and we had a discussion about pipes in
the cold. When
it's say, 30 degrees with a wind chill of say ... 25,
would materials
(pipes, ducts, etc) that's in the wind be considered at
30 or 25?
I know what you're thinking - what's a pipe doing
exposed to wind? But
that's a given in the situation, and not really a matter
to discuss. The
question is basically, do non animate object get effected by
the wind or
does is only apply to people, dogs, and other animals?
--------------------
They most certainly do. A couple winters ago, I had my
water valve to my
downstairs toilet freeze and leak. This is in a small,
unheated room in my
house with a crawl space of about 2 1/2 to 3 feet
underneath. The wind was
coming in the cracks around the access doors to the crawl
space. Combined
with the frigid temperatures (below 0°F), this brought the
temperature down
enough to freeze that valve. While waiting for the plumber
(who was dealing
with an unprecedented amount of frozen pipes) the water in
the toilet also
froze. Fortunately, it didn't crack the bowl, but it
did mean a couple days
with a space heater to thaw everything after the valve and a
portion of the
feed pipe was replaced. I've never had that freeze
before, even with the
temperature outside down to -30°F, but no wind. Even the
plumber said it
was the wind chill which was freezing the pipes.
