A friend of mine who ownes a air conditioner business gave me 30 feet
of 6 inch 30 gauge metal pipe to use for the main line of my dust
collection system I am installing. Anyone used this type of pipe with
success? My DC is a grizzly 2hp unit.

Thanks in advance.

Almost certain to collapse first time you turn it on...light HVAC
ducting isn't able to standup to the pressure drop of DC systems...

I've got several 5' runs of the 6" ducting from HD which is 28ga at best,
no collapses with full blockage on a 2hp woodsucker cyclone.

Sheet metal gauges run in increasing numbers -- thinner material so a
28 ga is, while not that much in aboslute thickness, a marked
percentage change (I didn't try ro look up actual nominal
dimensions). I'd be real surprised if a 30 ga HVAC duct would stand up,
but I'll admit I've not tried it. Worst that could happen would be it
just collapses, of course, so OP might as well give it a go if it was
donated material. I'd hook just it up and see what happens before I
spent a bunch of time hanging it all in place, though...

Yep!

It certainly should work fine as long as the pipe is never fully blocked.
Should the pipe become blocked and the pipe collapse, it would serve as a
very visible reminder not to do that again....

I just plumbed an entire shop with 30 gauge with the same Griz 2 HP
collector. Works like a charm. Most likely you won't get the joints
tight enough to pull the maximum suction. Even at the maximum suction,
I don't think you can suck it flat.
