Hydrostatic Test

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

Shop hydrostatic test gauge pressure is 527.55 psi at 70 F (the chamber MAWP = 405.808 psi)

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

Notes:

(1) Ellipsoidal Head #1 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 Ellipsoidal Head #2 and Ellipsoidal

Head #1.

The test temperature of 70 F is warmer than the minimum recommended temperature of 24.9 F so the brittlefracture provision of UG-99(h) has been met.

Parallel Limit of reinforcement per UG-40

LR = MAX(d, Rn+ (tn- Cn) + (t - C))

= MAX(2.4645, 1.2323 + (0.655 - 0.125) + (1.25 - 0.125))

Outer Normal Limit of reinforcement per UG-40

LH = MIN(2.5*(t - C), 2.5*(tn- Cn) + te)
