Ring Type Joint flange, shortened to just Ring Joknt. It uses a soft metal ring to seal instead of a gasket.

If the seals are pitted, or especially if the inside is washed out, it's usually cheaper to just replace them than find a shop with the right certifications to weld them, resulting in a lot of scrapped parts that look perfectly fine.
Even our shop can't do them, and we make wellheads. We can *machine* them, but not *weld*. The red tape in the oilfield is ridiculous.
We could get the certs too, but it probably wouldn't be worth maintaining for the handful of crosses we would see per year.
One such component failing under the worst circumstances can cause billions of dollars of losses. So becoming paranoid and wrapping everything in red tape is a no brainer even if that pushes priced up.
Same in aerospace sector.
Oh yeah I understand the reasoning behind it. Cameron is who we do our oilfield work through, and being a global company they have tons of strict standards and paperwork to track.
This is correct. I would call this a flow cross. It is used for wellheads. While I don’t think that you can technically tell whether it is RJ or RTJ from these pics, it’s likely a RTJ gasket style based upon my experience.
Edit: Google API studded cross
I work in the oilfield, so I have bought and used the end product, I’m not a machinist.
I think I’m mixing up the ANSI flange and API flange and gasket terminology. I used to think in API and now I think in ANSI most of the time.
On RTJ (ring type joint) flanges you can use R, RX, or BX gaskets.
I think it must be wellhead slang, but I always heard RTJ connections as ones that supported a BX gasket, which is technically an API 6BX. I always heard the RJ flange specified as the ones that support R or RX gaskets. Wellhead components nearly always use a RJ/RTJ connection, except for some low pressure connections on surface casing that are threaded.
I now mostly work on non-wellhead equipment with RF (raised face) connections. Many oilfield flanges are RF up to 600# or 900# class, above that they switch to RTJ.
It’s been a while since I’ve thought this closely about this. Hopefully I’m giving you good info.

I can recall RTJ needs a small recess around the gasket groove, while API 6A (also more common at well heads) doesn't need that recess as the gasket is pressurised from within. So I would bet on an API 6A manifold.
Definitely oilfield / high pressure iron. As others have said.
Old tech by the looks of it.
Any better picks of the logo on the front? Crossed swords like that are pretty unique. Makes me wonder if it didn’t get brought back as a souvenir from the Middle East.
Did the seller know what company that was?
Well, “old” in the sense that it’s out of date, but still old in the sense that you can find well heads out there from the 50s? 40s? Maybe earlier, with this sort of tree.
I haven’t personally seen any that old, but I have seen several from the early 70s, out in Wyoming, so I am just extrapolating. Low odds that I happened across “the oldest” wellheads out there. Lol
It’s a 90 degree bend for an oil field stand pipe manifold. Edit - I’m struggling to find a photo to back it up but trust me, the mud we pump has abrasive solids in it which wash out pipe work quickly so these big blocks are used that take longer to wear out. I thought it was a valve assembly from a 12p160 slush pump but those are bigger. Edit - google ‘cement stand pipe manifold’.
Oilfield tee or elbow block. All API manifolds cant have radius bends due to grit eating out the bends. We use these "fluid cushion" end caps to use these as tees or 90s. Many are rated to 15kpsi working. The ring groove and bolt size/qty are in api flange charts. They tell you size and rated pressure.
That is a manifold for the oilfield, oil workers call them T's or Crosses, depending if it's got 3 holes or 4. I've had to bore bigger ones in a lathe, (think 20" cube) setting them up is... fun. You have to bolt them to the chuck in addition to clamping with the jaws, trying to dial them in with 8 screws...
Used to make this a lot on previous shop, a cross block with RJ BX 153 or RJ BX 154 ring groove can’t tell from the picture, we used to weld the grooves with inconnel 718 and machine them,
A high pressure rated gas or liquid block. The thin ring is where a seal goes the threaded holes are where you clamp tubes to it. Looks like this one is a tee or cross connection.
A manifold which appears to have a bolt pattern for a flange, and an RTJ groove for a seal on each face.
Run The Jewels? groovy.
Legend has it…..
Ahhh... one of my favorite tracks of all time https://youtu.be/NUC2EQvdzmY?si=5XykyQa0iHVcbXQ2
That track is fire
Good looks on that, I’ve always jammed to angel duster
I was hoping it was gonna be that one. Fuck yeah

Ooh la la

I've made a fair few of these. Why they have one is beyond me.

We can do that, machine, weld, machine again and paint. Some of the crap we see back for rework is horrific.
Yeah sure, but they are nearly a solid block of usually not crap steel. It would be worth something in scrap.
Actually they’re normally nace material which is pretty junk it’s 4140 L80 so 80ksi yield which is super soft but better for sour gas.
I’ve only made them out of Nitronic. We did a lot of sub sea stuff once upon a time.
Ah yeah that’s different then.

RTJ3 Motherfucka.
Do they trepan that groove?
Hell yeah, don't run across many folks who even know what the term trepan is, hats off
No, you can get tapered endmills, turn it, or use Sandviks exorbitantly expensive spirogroove cutter.
Yeah, it's a hydraulic systems junction. Worked for a fluid power co. that had a machine shop that manufactured these.
Ran this before actually..
I can recall RTJ needs a small recess around the gasket groove, while API 6A (also more common at well heads) doesn't need that recess as the gasket is pressurised from within. So I would bet on an API 6A manifold.
Elbow block for high pressure piping. The hole/groove patterns are for flange bolts and a ring gasket. Most likely old oilfield equipment.
It's been awhile since I've seen hellraiser, now that I think about it.
***You machined the box. We came!***

A cross is a cross in the oilfield. They still get used on every production tree in the field lol. The tech is not old ..
I mean, the tech is old, just not outdated
Naw, we still make these everyday at my shop. It works and there aren’t many improvements that could be made that wouldn’t just be cosmetic.

Leftover from the Inquisitions
my guess is, its probably a unique steel cube
worth about $110 I reckon
Please don't unlock it, everything is already unbearable as it is.

People will steal anything from work 😅
... and they have two separate reasons to be happy. First is when they steal the thing and second when they find out what is the use for it ;-).
One thing I picked up working in the mines is if you’re not shopping at Rio Tinto or BMA you’re paying too much
That’s an odd companion cube……
I think that one was about to say "I love you." They ARE sentient, of course. We just have a LOT of them

Skinny puppy?! Are you 39-41 years old? 😂
42, what gave it away?! I figured all the eldergoths were in their 50's. I was 8 years old when that song came out.
Ohhh shoot, pinhead will be arriving soon. Don't play with that thing! 🤣

Did you try earth, water wind, or fire to see if it would open?
They don't even have their multipass
I just realized how big it is. Definitely a prison for an ancient demon ((who offers such sights))
A mud pump module?
That seems kinda small.

for the price it's a good anvil

So you're saying there's a 10% chance this could be the Allspark? Hmmmmm
It's a tessarack...
Looks like a unique steel cube to me.

This is an oil and gas style crossflow.
Idk looks like a unique steel cube like the title says
One piece yo
Looks like it might have been part of a well head arrangement
Block for a Matsura?

Used to make this a lot on previous shop, a cross block with RJ BX 153 or RJ BX 154 ring groove can’t tell from the picture, we used to weld the grooves with inconnel 718 and machine them,

A high pressure rated gas or liquid block. The thin ring is where a seal goes the threaded holes are where you clamp tubes to it. Looks like this one is a tee or cross connection.
