Hydrostatic Test

Shop test pressure determination for Chamber bounded by CABEZA INFERIOR and CABEZA SUPERIORbased on MAWP per UG-99(b)

Shop hydrostatic test gauge pressure is 429 psi at 70 F (the chamber MAWP = 330 psi)

The shop test is performed with the vessel in the horizontal position.

Notes:

(1) CABEZA SUPERIOR limits the UG-99(b) stress ratio.

(2) The zero degree angular position is assumed to be up, and the test liquid height is assumed to the top-mostflange.

The field test condition has not been investigated for the Chamber bounded by CABEZA INFERIOR and CABEZA

SUPERIOR.

The test temperature of 70 F is warmer than the minimum recommended temperature of -16,09 F so the brittle

fracture provision of UG-99(h) has been met.
