Flange as per ASME code VIII, div 1, appendix 1-6d

Flange as per ASME code VIII, div 1, appendix 1-6d

Flange as per ASME code VIII, div 1, appendix 1-6d

(OP)
Hi all
Is it mandatory to check rigidity for floating head flange ( fig 1-6 d ) which designed according to ASME sec8 div1 app 1-6 equation 10?

Thanks

lonlyboy, by my reading, it is not. I have not seen software which does so.

Regards,

Mike

Dear Mike as I find Aspen B-jac check rigidity for this flange but in pvelite there isn't any calc. for it

RE: Flange as per ASME code VIII, div 1, appendix 1-6d

Not familiar with BJAC (and many others, no doubt). I suppose it would be considered a loose-type flange, althought some ambiguity is present.

I'd say, permitted, yes, required, no.

Regards,

Mike

I agree with you ,but if we do it there will be sth. about 25% increase in thk. of flange.
so we as a manufacturer prefer to ignore this calc. but our client persist on that and i am going
to find some reason to convince them .

Thanks
