I might use Sch40 PVC for a line I'd set up for temporary use, but not
for anything I was going to leave in place for months or years.
Sch80 PVC is a whole lot stronger, but more expensive than any metallic
option.

I did our house's gas piping in iron, but when it came to putting
compressed air in the walls I went with Type L copper. Far easier to
work on-site, easier to repair in-place if something did happen to it.
