New bolting - bolt problem at asme nozzle connect to gre piping

The BDIA should be set to 0.625
It will display as 0.63 if you do not switch on precision but the setting needs to be 0.625.

Or if you use metric units
Input is 15.88 which if you then switch back to inch units to 3 decimal places gives 0.625 in

can you try my stupid suggestion: set Bltref for Nozzle = Nulref, then generate Isome again

@Bobby
I use New bolting. Bltref of spref is always Nulref.

Hi Pitch
i used inch for all Bdia. It's good for all except for this case. I changed nozzle to other spec and it worked. I will re-check it later.
Anyway I will note your suggestion and thanks.

Hi Gents,
Thanks for your help!

[QUOTE=corrado;87191]Sorry for my silly question but....have you checked BDIA attribute for each BLTP?

And why do you have set Bthkness to SUM 51 5 instead of simply 56 ?

BTHK 51 5 is working (i.e. sum 56 is considered for bolt calculation )
But BTHK (SUM (ATTRIB RPRO FLTH) 3) or BTHK ((ATTRIB RPRO FLTH) + 3 ) is not being evaluated for bolt length calculation.

Request expert to help on this issue urgently.

Hi Kanza,

Can I know from where you derived the naming phiolosophy for the Btse as  [COLOR=#333333]/NTC-1SB21ZZZZBBJJ.[/COLOR]
