Sajit, Paul

Click on the hyperlinck in my email: http:\groups.yahoo.com/ and then sign in with your password. In my groups you will find:

centrifugal_pumps
piping design

The file is uploaded in the group centrifugal_pumps under files since I could not find an upload area under piping design .

So Paul ,if it is not the right upload area then I apologize and perhaps you could tell me where I can find the right one..

Erik,

Where about is your Iso located. You need to be more specific as to where in Yahoo group.

Sajit

   George,

   Dimensioned isometrics are not only useful for stress analysis but also when

   you have complex piping systems such as the piping of a blast furnace .When

   doing a complete revamping within 90 days it is indispensible to have    dimensioned isometrics.
   90 % of the pipe spools are fabricated in the shop based on this iso's.    I have uploaded a file at http://groups.yahoo.com/ showing a dimensioned    iso. What can you do with such an iso without dimensions?

   Steve;
   Depends! Generally we are the same, iso's are for layout, orientation of    components. But the next level is an analysis of piping systems, CAESAR or

   whatever. Then you need dimensioning, but since it's a work in progress,    you don't want to invest the time in a full blown set of drawings. That's    where dimensioned iso's are really useful.

Gents+2
I have just had a friendly discussion with a South African colleague
who maintains isos are normally dimensioned and are used as part or the
formulation of the Schedule of Quantities; BOM; whatever.
My experience with isos is that they are comics that we give to the
pipefitters as a rough guide. Occasionally I have used dimensioned isos
to display fixed and toleranced dimensions around critical plant for
shop spooled piping, but in general I just use them as a sort of road
map. We are not talking 3D CAD here.
My question is do you guys normally put dimensions on Isos, and if you
do what sort of plant do you normally work with?

Cheers

Steve
