Running black pipe (2") - and need to go up 10 inches and laterally 16 inches - this is not a strait 90 degree fit, I will need to do something else - but I want to know what is the best option for creating an offset of about 1/2 to 1 inch? (add in 45s?) - I just didnt want to create a monster

    Got a picture of the space? Are you using threaded or press fitting?  Seems like 10” and 16” is plenty of room. Are you dealing with obstructions?

    Option 1: Use MegaPress fittings. You can cut the pipe to correct length to match up the pipe and press fitting geometry. 
    You may be able to rent a Ridgid Press tool or contact someone in the trade. 
    Option 2: Are you altering an existing system? Can you unthread and replace the longer pipe section with shorter section with room for union and 90?

    Viega recommends stainless for steam applications. 

    I edited my previous post to ask about unthreading the longer pipe section.  Is that doable?

    @PC7060 its connecting to a union at that location with a close nipple, i think i would prop have to cut it off and then try to get the threads out of the old section, gets harder that way.

    here are 2 choices. One involves more fittings the other requires cutting and threading (if you don't want to go the mega press option)

    After you make that expensive repair and you still have the same problem, What will you check next?

    @subdural, could you tell us what application this piping arrangement is on, what pressure and temperatures are involved?

    Another arrangement to consider is to cut off the end of the vertical and then use a 2" compression type (Dresser) elbow. Hopefully the horizontal is threaded so only a coupling and nipple would be needed to complete the connection.

    @EdTheHeaterMan i think that will work with the 2 unions! Piping is 2 inch black for steam @Pumpguy, i do not think high pressures. @EdTheHeaterMan (i see you are also a blender guy).

    Not at all, that is your graphic pasted onto a simple Paintbrush program (PaintS for Mac). Then I draw lines to illustrate my concept on drawings you are already familiar with.

    Don't forget about pitch to direct the return flow of condensate. You also don't want any low areas that will trap condensate.
