I just signed a contract for a property that has a 42x60 shop on it. I am looking to do something with the gas lines. I am thinking of making some kind of manifold system that will run along one 60' side of the building. I run 3 different gases normally and can have as many as 10 in the shop for different jobs. I would like 3 gases to be on 3 - 1/2" pipe runs w/ misc quick connects but what would be a good set-up for the tank area? I keep all my gases on brass quick connects so I can change fast and it won't affect the threads.
