MAWP/MAP selected for the shell side may not be coincident with the MAWP/MAP selected for the tube side (and vice versa).
The chamber MAWP listed above is based on the largest tubesheet MAWP values from the multiple design conditions. The lowest tubesheet MAWP values should be

15. Hydrostatic Test
Shop test pressure determination for Tube side chamber based on MAWP per UG-99(b)
Shop hydrostatic test gauge pressure is 65.000 psi at 70.00 °F (the chamber MAWP = 50.000 psi)
The shop test is performed with the vessel in the horizontal position.
