Adding Vents to Pressure Vessels
Adding Vents to Pressure Vessels
(OP)
To satisfy ASME section V111 – DIV 1 UG-99, 'Vents shall be provided at all high points of the vessel in the position in which it is to be tested to purge all possible air pockets while the vessel is filling' I'm looking at adding a vent to the top of a pressure vessel that is being built.
Since this is just for filling during hydrotest I am thinking of using a 1/2" plug that fits into a tapped plate that blanks of a T piece. Once the test is done this will not have to be opened again.
Also I am wondering if the thread can be dry sealed (because its a tapered thread) or does a thread sealant need to be used.
Obviously I am not looking for magic answers however I would appreciate a direction of where to look for answers.

I definitely recommend thread sealant.
