Which is the best connection for spool / jumper connection between clamp and collet connector.

[Nautilus82]

Good day all,

I'm trying to find following information about hub clamp and collet connector (size between 6" and 12")for deepwater oil field application:

- Have clamp and collet connector a higher bending capacity that the spool or pup piece they are welded to ?
- Which connector has the best capacity in terms of loads capacity ?
- Which connector has the best capacity in terms of misalignment capacity ?
- Can have a collet or clamp connector a higher bending moment capacity that an API 6A type BX flange ?
- What are the main advantages of a clamp connection over a collet connection and vice versa ?

Thanks a lot for your help.
