temperature of steam pipes?

Unknown

Depends on pressure. However for most home steam units a couple degrees above boiling (212 F) so about 215 F.

Does anyone know the maximum temperature for steam heat pipes coming out of a steam boiler?

If you are not superheating 705ºF @ 3200 PSIG.

Rod is right..

Bob is also right, but then, Bob has an awful lot of "A" dimension to spare.

I want to know where Bob lives so I can watch his house from a safe distance

At least Bob does not go to superheat.

about 215°F for a system @ 2 psi gauge near sea level.

For higher steam pressures it will be more, e.g. a 10 psi system would be about 240°F, 30 psi about 274° etc. but for residential heating even 2 psi is a bit too much pressure!

Note: at high altitudes, e.g. Denver, the steam temperatures will be a few degreees lower (perhaps 205° vs 215° for Denver) for the same gauge pressure reading, due to slightly lower absolute (atmospheric) pressure.
