Jop,

I am designing a tie-in spool for anhydrous ammonia and would like to know if there is a preferred branch direction for this service. Most of the piping branches that I've seen for anhydrous NH3 have either been off of the side of the pipe or off of the bottom of the pipe. Is there a reason that vertical, off the top branches are not used? My design is for a new 16" branch off of an existing 16" line.

Thanks,
Bob

Bob ...I've never done piping as large as what you’re dealing with, but I've dealt with anhydrous ammonia before, in refrigeration plants and cogeneration facilities. During all my projects I've never had the process engineer try to dictate any limitations on piping configurations. I don’t believe you have any issues with a vertical branch.
HEY ...I'm heading up your way the end of this month, could you please have the rain machine turned off by that time!??
