A few days ago, I noticed that there is some water dripping from the
gas pipe at the place the pipe entering our basement.

Then I found out that the pipe entrance hole is not sealed (we bought
this house just a year a ago). So I guess the water was because the
pipe is cold enough to cause the more humid air in the basement to
condense.

I tried sealing up the hole but it doesn't help.

My question:
1) Why sealing it up doesn't help. Basement is around 57F. Am I missing
something?

57 degrees seems quite cold for this early in the season unless you are
living in Canada. Why is the basement so cold?

2) How do I solve the problem? Is there some kind of material I put on
to at least not let the pipe corrode. I think the pipe is black iron.


Yesm the pipe should be black iron. Gas coming in should be near ground
temperature and thsi depends on how deep the pipe is and how cold your
weather has been and for how long. Closed-cell foam should do a good job
and three is fiberglass wrap available. I would go closed-cell to keep the
moisture out. Maked sure you either glue or tape the joints.
