I used to work for the gas company in Chicago a long time ago when I

Any additional help/guidance will be appreciated.

Blow up a balloon. Put it on the pipe. Does the balloon shrink?

The pressure from the balloon will be greater than anything the pipe will
ever see.

gas line pressure a few ounces max.

avoid ever pressure testing old lines, as it tends to cause leaks
