Why are civil natural gas pipes set up like this?

Easy to replace, isolate, detect and repair； You can add a blind plate to the ball valve flange, remove the flange cover and install another pipe, replace the medium for purging, testing, and install a pressure gauge, etc.
I just guessed without understanding. The coordinates of the underground pipe and the above-ground pipe are inconsistent. Adjust the coordinates like this. If they are all like this, then they are all wrong.
Well, yes, yes. The underground pipe and the above-ground pipe are not in the same straight line, so they can only be adjusted in this way. study * .
This kind of piping has elements of bao li aesthetics. It is simple and rough inside. What materials are used?
The key is not one, several are set up like this
The underground coordinates and the above-ground coordinates definitely don't match up. Why is there a blind board there? Is there a purge port left? Why not remove the valve and connect a short pipe to make a purge port?
If you can't reach it if you go straight down, turn a corner and pick it up: lol
What I saw is different from yours. The blind flange is under the valve riser. It is said to be used to clean the slag in the valve riser.
It's misplaced and can't be installed, so that's all I can do. If it's easy to clean, just a tee is enough.
The coordinates are different, so I changed them and added a compensator.
