Hi Mike
some dairy installations use tube-in tube exchangers for ease of cleaning. By using a serpentine pattern, expansion can be easily accommodated.
Before designing you may want to see whats currently available so you can either "borrow" the best ideas or just buy what you need. APV and Alfa Laval make some good stuff in the dairy industry.

Cheers

Steve

Subject: [PipingDesign] Shell and tube Heat exchangers

Greetings

Anybody with information on design of heat exchangers? I am starting out on a design, I am seeking some technical information, literature or any other guidance on how to correctly determine the innner shell tube lengths for a sanitary shell and tube heat exchanger(tubes to be built into a bundle). I would like to better understand thermal expansion effects and properties, stress related effects on welded ends, in order to prevent bending of the tubes. These tubes would be welded into end plates and specifying the welds to stop leaks is a concern.
