I watched the gas companys contractors install gas pipe
for a furnace and watet heater. They used pipe dope and
overtightened everything. They really reefed on the wrench
as they tightened each joint.

You could pressure test each section as you go. Pressurize
with air, and check for leaks with soap water.


Also, if you do use tape, be careful that you don't overlap the
end of the pipe with it. Shreads of tape can plug up jets in burners.
