Code allows you to retrofit that with a 1/2 x1 ell and a 1 “ new drop if the
outlets are 1/2” off line
Could you elaborate?

The branchlines are 1", 1-1/4", etc. with a tee and the drop is ½" pipe to the
sprinkler heads. Where I would normally design a 1" drop, they used ½".

I think 13 tells us in a round about way that 1/2" and 3/4" steel can only be
used as "Pilot Line" detector piping per Chapter 8 and Chapter 6. Look at Note
"B" in the allowed pipe size table in Chapter 6...it sends you to the pilot
line section in Chapter 8 and restricts those sizes to that use
