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 4.55 bar at 21.11 °C (the chamber MAWP = 3.5 bar)

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