Vent leaks, size of pipe

Options
Hi I have two separate jobs with water leaking from radiator 
both one pipe steam, one on third floor
one on first
the one on first floor is large 24 section recessed radiator 20” tall.
my question is there a chart to determine size of radiator and distance as to size of supply pipe ?
Radiator valves changed.  New vents
pressure troll at 1.5
no surge
