Kevin is correct, steam traps are sized individually. However, for 95% of steam line drip traps on saturated lines with proper line drip spacing, the condensate load is EXTREMELY low, much lower than all steam traps are designed, so a 1/2" TD trap is actually my recommendation over the 3/4" TD, which has a very large flow rate.
As for the concentric reducer, it would be better to use an eccentric reducer as to not pool the condensate, however you are more likely to get water hammer on the piping after the trap, and proper pitch should be used.
More importantly is the configuration of the main line drip leg and the piping of that to the trap.
