DEU Heatexchanger with Channels made out of plate

[Fernandiux]

We are designing a couple of DEU Heat exchangers and according to TEMA, the cannel is to be integral with the tubesheet.
Is it possible to use plate instead of forging for the channel construction? Tubesheet to be forged and welded to channel.

Thank you in advanced for your responses,

Fernandiux, yes possible and not uncommon.

Thank you Mike,
Do you know if there is somewhere where I can see more information about this?
It would be very helpfull since I have to convince our client that this is technically viable.

Jeez, it's just a R&W cylinder welded to tubesheet one end, closure on the other. What's not viable about it?

I guess along with the Code of Construction, you might see API 660, section 12, if it applies.

Regards,

Mike
