looks like gas lines. could be for an old generator. removed gas meter. no one can know except you. do you see the pipes inside, in crawlspace, basement?
what size are the pipe?
Those are pipes sticking out of a ground with some sort of a cap on top of them.
Looks like unions.
Prob 1/2 inch copper
Cap was tape
Half of a union anyway. If the pipes are copper, I would think it is where an irrigation manifold was at some point.
I think the same Michael.
it’s all so obvious now !
I concur. 2 abandoned gas meter pipes.
