I have a new heat exchanger with both shell and tubes 304L and rated at 150 psi @ 350 F, water on tube side, steam on shell side. How can I calculate the pressure rating of the tubes at 160 F? Is there a graph or equation? Steam will be regulated through a control valve, but max. upstream pressure is 160 psig. Would I need a PSV if the exchanger were blocked in? If I size a PSV for thermal expansion on the tube side, would I use the saturation temperature at 150 psi?
