Expansion fitting??

 Anyone have any idea what this is. It’s on a heating line for a school. Thinking it’s some kind of expansion fitting but cannot find a vendor that knows anything about it.

Looks a lot like a Metraflex Metragator.

Hi, Pure guesswork here, but if this is steam, and if those two ports on the underside of the unit aren't blocked, perhaps this is some sort of water heater. Could be a way of adding space heat via hot water...

Are there any marks of any sort on it?

Yours, Larry

Hmmm very interesting....Expansion joints are used on very long runs of pipe. Anyone, I've  seen in the field, never had a pipe tapping like that or a drain...I defer...Mad Dog 🐕

I believe it’s an expansion fitting.

Ok thank you for your input. It is for a heating hydronic line. There is one on the supply and return. Unfortunately they are no markings or stamps on it that I saw. Any idea who carries something like like so far Yeager, fugerson, Sommerville haven’t been able to help.
thanks

See: the bolt with it's head projecting towards the camera (right of center) and the rust line immediately to it's left? Also notice: the "scrape track" of the bolt-end on the smaller dia. pipe. Seems: like the righthand flange assembly and pipe...pulled away. My vote is for: expansion fitting.
