To Tony Paulin

Sir,

“When a WRC107, 297 or FEA calculation shows that a Code violation occurs, removing one of the components (pressure in this case) is generally not advised." Neither I am adding pressure thrust in the external forces & moments input of nozzlepro.

For SA387 Gr-22 Cl-1 material in ASME Sec-VIII Div-1 with operating temperature of 549C, Smc = 117.819 Mpa, Smh=48.744 MPa,Syc=206.84Mpa, Syh=163.4Mpa & STc = 413.68 MPa input, at 3350mm IDx42mm thk vessel 7 1219.2mm ODx 22.23 mm nozzle, nozzlepro local stress failure occures just for internal pressure of 1.01 Mpa only without any external forces / moments.

Is the arrangement safe from Sec- VIII Div-1 ?

regards,
