Material A 213 T22
circumference crack accrues between the fines, the crack is below the soot blower and the finned area around the crack is completely.

thanks Mike Halloran
but it is written at the heat exchanger nameplate shell hydrostatic test pressure 17.5 bar and tube hydrostatic test pressure 10.5 bar
Hi every Body ;
there is a heat exchanger shell side pressure 17.5 bar and tube side pressure 10.5 bar always when i test its sell side it is ok ; but every time i test the tube side some of tubes leak at pressure 7 bar, i plugged them and do the test again another tubes leak and so on.
