It seems to be an air pipe with a ball valve installed?
It should be a domestic gas pipeline. This phenomenon is mostly due to the convenience of installation, but the upper port should also be added with a flange blind plate. Haha, it's all caused by the irresponsible supervisor.
How did you leave that gap in the middle?
Can ball valves be used in gas main pipelines?
In order not to block the dog search notice, it turned itself into a bypass. What a caring channel, thumbs up.

You see what others don't see
Unless a flow meter is reserved in the middle, the flow meter is not in place later! Otherwise, it’s a waste of work and waste. I don’t understand why it is so high!
