api 617

dear friends

   I have studied about this standard(nozzle allowable loads)and i have seen one dacument from Thermodyn about a compressor with 4 nozzle( 2 inlet and 2 exhuast)and in this dacument each stage shuold be satisfied according to api 617 .
my question is this :should we not check all nozzle load with togethers? and api617 is for 2 nozzle compressor,isn't it? is there any guideline about this kind of compressor? Received on Tue Sep 23 02:54:00 2003
