What is this thing on a deaerator?
(OP)
I was on a job site last week where we got convinced to supply a deaerator, which is not normally part of our scope. So, I have very little knowledge of deaerators and their valve requirements and such.
Anyway, the company in charge of doing all the piping has installed this thing (see attached) on our DA and I have no idea what it is. Can someone tell me what it is and what its purpose is?
Cheers

Both the first two options seem pausible.

Possible... seem possible.

Mulholland, those welds made me wonder too. It's hard to tell in the pic I attached, but those are actually threaded rods.

The welds definitely look "home-made" or "after market" and are suspicious.
Haven't seen chemical devices like that - but won't reject that identity. No manual? Parts list? Instructions?

I'm going to say it's not a thermocouple. I have seen a lot of thermocouple on our equipment, and others, and not one like this. Granted, I've been wrong many many times before.

Is it a cascade type deaerator? If not I would not recommend using it and dose the chemicals before (the alkalizing agent) and after (oxygen scavenger, volatile chemicals) the dearator for several reasons. For a cascade type it might be usefull for dosing the oxygen scavenger, but on the other hand it is almost useless to use an oxygen scavenger in combination with a cascade dearator.

Having worked for RCS for 17 years, this is definitely not a corrosion coupon "retractable" holder. Looking at the end, it appears this might be a check valve. If it is, this is for injection purposes. If you look into the end and see pins for an electrical connection, then this is a corrosion probe, though not likely. Usually, chemical injection quills have valves at the end to shut off the system and isolate it while not being used. This was inserted and fixed so it is not retractable, but adjustable is more like it.
My guess is injection device.

Just above the valve, it looks like that's a corporation stop that is essentially a compression gland. You'd attach a safety chain and loosen the stop, and internal pressure would back the quill out to the limits of the chain. At this point, the quill is no longer passing through the bore of the valve, and you can close the valve and isolate the system. Then, you'd have some sort of way to bleed internal pressure in the quill, and you could remove the safety chains and release the corporation stop and remove the quill.
Here's a pdf of the type of device I'm thinking of. See if it jives with what you've got.

I found out today that it is a chemical injection port.
Many of you got it right. Impressive.
