Welcome to the forums.

it's not uncommon for metal gas line to be rusted in the presence of moisture.

If that piece of 1/2" pipe is connected at both ends then you have to cut it, unscrew both ends and replace it with two pieces of pipe and a union. You'd need two pipe wrenches to do the work.

A picture posted here will allow us to comment further on the issue.
You may just need to scrape/sand the pipe and repaint it.

Your best off calling a pro in if you are concerned... We dont know your skill level and gas is not something to tackle if you have never worked with black pipe before..

Possibly a pro will offer to repipe for you in CSST... ( Trac pipe)
