Tubesheet Flatness Requirement
Tubesheet Flatness Requirement
(OP)
Does anyone know what the recommended tubesheet flatness spec is for sanitary shell and tube heat exchangers where the bonnet pass rib does not have an actual seal but the rib face is metal to metal seal to the tubesheet face in multi-pass units? I contacted TEMA but since that isn't listed in their guidelines they cannot provide a answer for the requirement.





RE: Tubesheet Flatness Requirement
What size unit, what leakage can you tolerate? How would relative deformations between the tubesheet and pass ribs be accommodated?
I'd think sealing would be an iffy propostion unless a pretty viscous fluid is involved.
Flatness? The flattter the better, what can you achieve?

Not every feature is subject to "industry standards".
