I don't believe there's a maximum slope specifically for the pipe (pipe is run vertical all the time), but there are a few rules in NFPA 13 to be cautious about:

(1) Extended coverage sprinklers must be listed for sloped applications above 1 in 6 (see NFPA 13-2016 8.4.3), as with Residential (NFPA 13-2016 8.10.2.2)
(2) ESFR sprinklers can only be installed for slopes less than 2 in 12 (NFPA 13-2016 8.4.6.2)
(3) Sprinkler spacing is determined along the slope of a ceiling (NFPA 13-2016 8.5.3.1.2 & other sections)
(4) Sprinkler deflectors should generally be aligned parallel with the slope (NFPA 13-2016 8.5.4.2)
(5) For attics or combustible concealed spaces, there's a handful of extra rules (see NFPA 13-2016 8.6.4).
(6) Sloped ceilings require increases in design area (see NFPA 13-2016 11.2.3.2.4)
