    What is the definition of "swing joint" in gas piping
    I am running steel gas pipe in a new addition. There are code references to fittings that are not allowed in concealed places. One of these is "swing joint", but I can't find a definition anywhere on the web. Can anyone please explain what this is?

    A swing joint,)see image) is the same for gas or water piping. It can transition to just about any direction or angle that you wish. Regards, Tom

    Thanks. What I need to do is go up, over a beam, then back down a wall. Just like your drawing only upside down with longer pipe lengths. Is it because the joints are close to each other or because they are not strapped that makes it a swing joint?

    The pipes can be any length. It's the elbos that make it a swing joint. They can turn, (swing) in any direction that you desire. Good luck, Tom

    Since I am prohibited from using a swing joint in a concealed space, are there any tricks to accomplish this: From a horizontal run that is parallel to a beam I need to go up and over the beam and then down a wall. What I am trying to do is just like your diagram only upside down with longer pipe lengths.

    About the only "trick" I know that will get you up and ove and still keep you legal would be to run the job in soft copper. Good luck, Tom
