Bolt Length calculation for loose flange

Are you talking about NEW bolting method?
The Bolts required for the Flange need to be longer to take into account the Flange Thickness and the Wall
Thickness, typically BTHK has to be set to ( RPRO FLTH + PWALLT(1) ).

Dear All,
In PDMS, How to set bolt reference in case of lap joint and stud end assembly.
Can we use normal bolt reference?

Using Old Method, then you can use normal bolt reference at Flange SPCO level.
Old method is not sophisticate.
I would suggest to move to the New method.

Dear Corrado,
I am using old bolting method. At level SBOL, value of Length should take consideration of flange thk and wall thickness.
At what component, I have to set reference of bolt?

 

Make sure you have a DATA element with key attribute set to FLTH in your category DTSE.
By the way, why are you adding the pipe thickness to the flange thickness?

I am using Lap Joint flange with Stub End and i need that sum Pipe Thickness in the bolt.

That's clear. Thanks.

Try typing the following syntax in the Model Command Window where the flange is your CE:

q  ( rpro flth + pwallt(1))

Does it return a result?
Is it ok?

Ok. Clear.
I would check if the PDATAB is correct.

 

In your previous image, the system looks for a 72.6 diameter.
72.6 is not included in that PDATAB.

By the way...this comes from the Piping Catalogues and Specifications TM-1840 Training Manual:

The catalogue must always be built in metric units
