In my crawl space I have a fairly convoluted maze of black iron gas connections which only serves 2 appliances.
During basement renovation this maze gets in the way and I would like to remove most of those connections and replace with as direct as possible lines to my appliances. I, however, don't want to take apart the wall to replace pipe all the way to the outlet. So I will inevitable end up with something like two male threaded pipe ends that need to be linked with each other.
Is there a good, code-compliant way to connect those sections of black iron pipe houseline? Something like flared connection would work, perhaps, but I can't find anything suitable for iron pipe.

You need a left-right coupling/nipple set, available at any plumbing shop and legal to use in that application (but check with your AHJ to make sure).
As mentioned elsewhere, a traditional pipe union is generally not acceptable anywhere within the envelope of the foundation of the home.
