Any particular reason why you're using pipe rather than rods? The rods
are copper plated steel and usually much cheaper, as well as being
easier to drive.
As far as flashing goes, why not use copper wire? Inductance is roughly
the same, and the increased AC resistance from skin effect is small
compared to the inductive voltage drop. Then you can use standard
clamps/exothermic welding, etc.
Unless you happen to have flashing, then, by all means, use it.
(Flashing is good for RF grounds where you want to minimize power
losses, but in a lightning protection situation, the power dissipation
in the conductor isn't a huge deal)
