Pad flange calculation base on ASME code UG-37

[ChiangJaron]

Hi, every expert.

I would like to discuss the pad flange calculate base on ASME code UG-37.
How to estimate the area as attached marking portion since tn=0 and this type ?

On the side, How to make a model as above mention by PV-elite software.

ChiangJaron, see your sketch and UG-37. No area contributed by nozzle neck, A2 = 0. Area contributed by reinforcing element of te and OD, ID, etc. for A5. A1 & A4 per UG-37.

Doesn't appear to me that PVE will exactly model this connection, but it should be possible to perform the calculation per above.

Regards,

Mike
