If you use the aluminum tubing(Kitec) you can find it with a metal
detector. The other stuff can be located with reasonable accuracy by
wetting the floor and noting where it evaporates first.

I have tubing in my floor and it is awesome. I definitely recommmend
it. I do not have any equipment anchored to the floor. I did place a
steel subframe in the floor for a crane, but I am not sure that will
ever get placed.

You could go to a thicker floor or go around the equipment. I would
probably lean towards the thicker floor. With a 6+" floor you could
still sink a 4" anchor directly above a tube and not have to worry
about hitting a line.
