shell and tube geometry
(OP)
is there a standard or rule of thumb for the minimal allowable spacing between the tube OD and the shell ID?

RE: shell and tube geometry
As for minimums: remember, once you design it, someone is going to actually have to build it. Keep that in mind when getting aggressive with your OTL vs shell ID.

RE: shell and tube geometry
What type of exchanger are you dealing with , fixed tubesheet or floating head ?
In case of floating head exchangers floating head flange require large bundle to shell clearance as compared to fixed tubesheet exchangers. This clearance is function of design pressure , greater the design pressure larger is clearance.
If you have access to HTRI design manuals you can look into graph provided therein.
RE: shell and tube geometry
Shell ID clearance
6 -12 1/4"
13-24 5/16"
25-33 3/8"
34-47 1/2"
RE: shell and tube geometry
Are these clearances diametric, or radial?
