Weld neck flange ASME B16.5 failure

Weld neck flange ASME B16.5 failure

Weld neck flange ASME B16.5 failure

(OP)
All,

I'm checking the capacity of the ASME WN Flange #900 for 24" offshore pipeline. I'm checking it for the external loads (installation loads - axial force and bending) as per Kellogg's method. I don't have any internal pressure as this is installation case not operation.

I know that #900 ASME flange has pressure rating equal to 15.5 MPa. My question is if my total equivalent pressure i.e. (4F/πG^2)+(16M/πG^3) exceeds 15.5 MPa does this mean that the flange has failed?
What are the criteria for flange failure in this case (S-lay offshore pipeline installation)? Any useful reference?

Thank you.

I'm not familiar with Kellogg's method.
Without pressure, or torque, it must be P/A + Mc/I
