Hydrostatic Test

Shop test pressure determination for Chamber bounded by Ellipsoidal Head #1 and Ellipsoidal Head #2 basedon MAWP per UG-99(b)

Shop hydrostatic test gauge pressure is 357.63 psi at 70 °F (the chamber MAWP = 275.1 psi)

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

Notes:(1) Ellipsoidal Head #2 limits the UG-99(b) stress ratio.

The field test condition has not been investigated for the Chamber bounded by Ellipsoidal Head #1 and EllipsoidalHead #2.

The test temperature of 70 °F is warmer than the minimum recommended temperature of 0.5 °F so the brittle fractureprovision of UG-99(h) has been met.
