I did a Google search for "lack of recoil in rail guns" and found
three hits.  One in groups.google.com, one in archive.org, and one
in alixus.wordpress.com.  None of these sites appear to require
peer review before they publish.  I tried the same search in Google
Scholar and got nothing.

All your "papers" babble on about a static case where the projectile, or
whatever you want to call it, does not move.

Of course there is no recoil in that case and such is blazingly obvious
to anyone that knows anything about the laws of motion.

Recoil occurs in a gun of any type because the projectile is ejected
from the launching mechanize, whatever it may be.

Your device doesn't have recoil because it doesn't launch anything, the
projectile, or pipe in your case, simply rolls off the end of your
device hence there is no recoil.

You also babble on about the friction of the projectile on the launching
device, which is just nonsense. Any friction between the projectile and
the launcher results in a force on the laucher that acts in the same
direction as the projectile, while recoil is a force on the launcher
that acts in the opposite direction of the projectile.

To observer recoil, hold a garden hose pointing away from you and turn
on the water. Observe that a force occurs that is pushing back at you.
