I want to put a dryer in but as of right now I have to run the vent
directly in front of some black pipe... they will be touching unless I
put something to put the vent pipe off of the black pipe. Don't know if
I'm making sense... is the heat from the vent enough to cause problems?
Thanks,
Jay

Dissimilar metals can be an issue like copper and galvanized pipe. I would
just tape the black iron pipe and install METAL exhaust pipe. Read the
directions, every 90 degree elbow increases static pressure. Bigger pipe is
better some times
