MoverZ,
Dear Good Shepherd,

I’m bleating on piping flange checking. For the flange design I have no bleat. :-)

About EN 1591. The Mechanical Model details are saying "Only circumferential stresses and strains in the ring are considered. Radial and axial stresses and strains are neglected".
Applying the model for ASME Flanges could be a reason for some bleating?

3D FE for piping flange checking just sounds great, as engineering! Some additional project cost...another bleating!

My best regards,
