Hydrostatic Test

Shop test pressure determination for Chamber bounded by SD Head 1 and SD Head 2 based on MAWP perUG-99(b)

Shop hydrostatic test gauge pressure is 21.14 bar at 25 C (the chamber MAWP = 15.43 bar)

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

Notes:(1) SD Head 2 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 SD Head 1 and SD Head 2.

The test temperature of 25 C is warmer than the minimum recommended temperature of -23.61 C so the brittlefracture provision of UG-99(h) has been met.
