I thought this was about using 1" st ells in a tight spot, not changing uprights to pendants. And of course you can use them and they're readily available through plumbing suppliers if your sprinkler supplier doesn't have them. They come in reducing types, in black steel, galvy, stainless, bronze, and in weights (strength) equivalent to schedule 40, 80, 120 & 160. Very common for industrial boiler application.
