The vessel is low pressure (3 psig design) and does not even need to be Code Stamped; however, our client requires it to be Registered regardless.
The vessel will operate from 10% to full and should typically be at atmospheric pressure.
The test pressure is only 4 psig, however, with static...
It is my understanding that when hydro testing a vertical vessel in the horizontal position, that the test pressure must be increased to accomodate for the static head. The fabricator has stated that the Code does not require this and therefore will not test higher than the Code calculated value...
