Hi guys,

Can any one clarify this query? I am designing a feed tank of pulverized coal. I have provided a nozzle at the top of the tank, for pressure safety valve. Is there any possibility of taking a tapping in the above said nozzle for providing another pressure safety valve?
My nozzle size is DN80. If so, then what would be the size of the tapping nozzle? Also, what would be the pressure setting of both pressure safety valves?

Regards

Ram
