Chamber design MDMT is 20.00°F Chamber rated MDMT is -55.00°F @ 55.92 psi Chamber MAWP was used in the MDMT determination Chamber MAWP hot & corroded is 55.92 psi @ 325.0°F Chamber MAP cold & new is 57.14 psi @ 70.0°F Chamber MAEP is 15.00 psi @ 325.0°F External pressure rating was governed by the vacuum ring Top Plate of Expanded Chamber. Notes for Maximum Pressure Rating:

Note # 1. Details The largest tubesheet MAWP/MAP values have been selected from the multiple design conditions to maximize the hydrotest pressure and to comply with UG-20(b). The 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 considered when determining the final chamber MAWP. Refer to the Tubesheet Maximum Pressure Report for the lowest tubesheet maximum pressure ratings.
