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.
