Hello everyone, I have a question about the assembly activites of a heat exchanger which has a floating head tube bundle. Tema type is BES for an example and the length is over 6m. First we pull the bundle, than cleaning and inspections are done for both the bundle and the shell. Next we insert...

@georgeverghese Thank you for your contribution. Minimum CW feed temp is ambient temperature which is around 10-15 °C and for propylene feed we may consider it is max 70 as inlet line's flex. temp which is also shell's design temp. Tubes are strength welded to the tubesheet.

@georgeverghese It is AJM and the number of pass is 2 on tubeside. Op. Temps; Shell: 51 °C and Tube: 42 °C Design Temps; Shell: 90 °C and Tube: 70 °C

@EdStainless Thank you for your reply. We weld the plugs to the tubesheet.

Hello, I have a question about a heat exchanger which is tube side service cooling water and shell side propylene. It is fixed tubesheet heat exchanger the shell side's hydrostatic test pressure is 38 kg/cm^2 and the tube side's hydrostatic test pressure is 9 kg/cm^2 During maintenance...
