EXPANDED TUBE WALL REDUCTION FOR HEAT EXCHANGER
(OP)
What is the recommended tube wall reduction when 1" O.D. 14 BWG MIN or 12 BWG MIN admiralty tubes are expanded in the naval brass tubesheet of a shell and tube heat exchanger?

Tube side 75 psig @ 250 deg F for both exchangers.
Shell side 175 psig @ 250 deg F for the exchanger with 14 BWG MIN tubes; and Shell side 625 psig @ 250 deg F for the exchanger with 12 BWG MIN tubes.

I would strongly suggest that you fabricate a small mock-up of the tubesheet and roll the brass tubes into the tubesheet for subsequent pull out tests. The operating temperature is low enough that tests conducted at room temperature will provide you with comparable pull out strength values to optimize your design.

Here is their catalogue that has some general information in the lead in.
