Identifying a steam system component

This one has us baffled! It is a component in a low pressure steam system in Philadelphia, about 16" diameter, and is leaking...not sure what it is or what is does (or did) and wondering if you may be able to identify?

The first picture is a side view and the second is a bottom view (looks like there used to be an actuator?)

    Looks like an expansion joint, which lets the pipe move as it expands so as not to put any strain on the joints.

    I would sacrifice a small chicken to the steam gods and take my chances with opening that hatch.

    That does appear to be a motor mount.

    How about a bolted flange with a plug in it, which would turn the whole fitting into a tee. The flats could be for a zone control for the tap of the tee??? (Go ahead open it, small chickens are cheap ;) )

    Off the bottom of a main?

    My first impression was steam-turbine or zone valve.

    WAG........... Designed for a zone valve. Wound up as just a section of pipe, never used as intended.
