Folating head split ring connector

[MichaelDexter]

Hello All
I have floating head heat exchanger, my question is about split ring connection
Floating head is acc. to TEMA STYLE "B"
Design is based on TEMA, but it is no reqiurement

Usually split ring connector I saw as partial ring with 4 threaded holes, see sketch.

My question are (see sketch):
- is it a popular solution ?
- stud bolts going through split ring connector have one nut only ?
- are any recommendation for material of split ring connector, I prefer S235JR, P235 or P265GH (tubesheet, split ring, flange are in P265GH, stud bolts C45E)

By the way: split ring it TEMA = floating head backing device ?
In TEMA RCB-5.141, Y= from code fig. 2-7.1 using K=A/B - I can't find it (fig. 2-7.1) in ASME VIII div 1, do you know where is it ?

Thanks in advance

Lets take this one at a time.

It looks like the split ring connector is there to bolt the two split rings together. I have not yet seen this type of assembly in my dealings so I would say this is very uncommon at best. If you do go in this direction, which I don't see anything wrong with it, due note that bolts at the floating head will need to be longer at the split ring connector.

I find it very hard to believe that there is not a nut on the far side of the connector. I think it is just not shown in the picture.

I would make the split ring connector out of the same material of the split ring.

Split ring is the floating head backing device.

Hope this helps.
