Bending moment of clamp connector

i am a new pipe stress analysis. I'm doing nozzle load check for clamp connector (Grayloc type). the load case is OPE case (W+P+T+D+Wind). However, the require Bending moment is very big inwwhile bending momment capacity of hub is very small. I tried to re-routing the pipe to reduce the bending moment. However i all most node are failed bending moment. i checked with manufacture and they said the bending moment capacity is primary load (w, p). So i am confusing that i use the bending momment capacity in OPE case is wrong. Could you advise me the solution?

Hi,

To my knowledge Grayloc type clamp connector can take bending loads. I presume your modelling technique is having some lapses.

Try to model it correctly and show this to your superior.

Thanks R.K,
I checked model and everything is right. I also ask manufacturer for assistant and I'm waiting for.

Hi Again,

Can you please specify, What is the moment you are getting there? Since; Grayloc type clamp connector (with it's arrangement) will take considerable amount of bending without leaking.
