No.
NO!! Black iron pipe has a special coating to resist the highly corrosive effect of natural gas. Galvenized pipe CANNOT be used for gas service.
Because that is what is used for gas.
You should use black pipe -- Galv. pipe will flake off inside of pipe
Drip cup should be 2 and 1/2 times the pipe being served. Check local Gas Code bylaws for proper information.
Absolutely Not!

To properly cap off a gas line, you should first turn off the gas supply. Then, use a pipe wrench to tighten a gas line cap onto the end of the pipe. Make sure the cap is secure and leak-proof to prevent any gas leaks. It is recommended to consult a professional if you are unsure about how to cap off a gas line safely.
Either shut the gas off at the meter or install a valve on the pipe. As long as you don't have an open flame somewhere close to the gas line and have everything ready, you can take the current flex line off and install the valve with little gas excaping. Use pipe dope on the threads of the pipe instead of Teflon tape. This lets you cap the pipe with your thumb while you apply the pipe dope. Then just install the valve and tighten, making sure to hold the pipe so that you don't disturb the next joint further down the line.
Fill pipe?
Pressure testing with an inert gas after the line is isolated from the supply
So it doesn't explode.
