RE: Long Weld Neck Nozzle or RF pads?
In my opinion an RF pad should be used only when space or functional constraints exist. A pad requires a larger hole in vessel and in case of damage to the sealing gasket is more difficult to repair.

Additionally, it is going to depend on what will be connected to either the Pad or LW Neck.
Connection the the Pad s a studded connection and for the LW Neck a standard bolted connection.
Typically, a studded connection is used where there is minimum clearance on the component being cnnected, meaning that there isn't sufficient room for a full lenght bolt to be installed.
Hope that this helps you out.
