Black Iron Pipe- Dissimilar metal?

The gas line that runs in my basement (1" black iron) is touching the steel support beam. Is that an issue of dissimilar metals touching? Corrosion?

Iron to iron, probably not. I like to cushion any pipe against a hard surface with a strip of rubber, etc. just for a warm and fuzzy.

99.9% chance of that black "iron" pipe really being steel. Iron hasn't been used for threaded piping for about 75 years, maybe more.
