The1. 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 be2. considered when determining the final chamber MAWP.
