We're installing some mounts for solar panels and it requires that 5"
diameter steel pipes are embedded in concrete. I'm worried about the
pipes rusting up.
What's a good, anti-corrosion coating to use on the pipes before pouring
the concrete? Thx.

for long term durability use galavanized heavy wall pipe, then fill pie sticking out of cured concrete with motor oil.
a friend did this over 30 years ago when he put up a fence in the yard, so it couldnt rust out.
he was replacing a fence that had rusted out
The solar company sold us an engineered package of equipment.
There are four, 265 watt panels per mount. The engineering
specifications for the mount specify schedule 40 or schedule 80, five
inch pipe for the main vertical support. This vertical 5" pipe is
embedded in ~ a cubic yard of concrete. The lowest wind-rated part of
the system is 90 mph.
If we see dark clouds a'comin, I guess we'll be unbolting panels and
taking them inside.....
Sounds like a lot of money for the install. Did you buy the panels
I get calls all the time about solar, but I don't talk to telemarketers
on stuff like that. They offer a lease and they get all the tax
credits. At my age (70), I don't see a payback.

The homeowner I'm working with paid cash for the equipment and
engineering plans. It's great equipment at a great price but solar does
have a relatively long payback.
I think the homeowner is thinking about brownout/blackout conditions at
world's end. It's kinda hard to put a value on that.

Ok, I thought these were for running cables under a cement floor. The
OP's post was rather vague. Now I can see that these are support posts.
However, the tar should prevent rusting. Just brush on that liquid
roofing tar (not the roof cement that gets trowled on.)
(Wooden power poles with creosote would probably work as well).
