    Upcoming changes in ST3

    For those that don't have access to the Solid Edge newsgroup, this it what has currently been revealed about upcoming changes in ST3. Regarding the GUI:

    First look at Solid Edge ST2

    Siemens just launched the first preview of ST2 So far I'm most excited about the new Simulation module. That is what an built in FEA system should look like! Not like the lackluster FEMAP Express. The ribbon bar is still there though. Hopefully the modifications to the QAT will be enough to...

    Possible to variable control drawing view scale?

    I would really like to know if it is possible to control the scale of a drawing view with the help a variable, I'm guessing no, but you never know.

    18" Class 2500 flange

    I got an easy question today from a sales guy, well thought it would be an easy question... He asked me if there was any problem with designing a valve with an NPS 18 Class 2500 flange and my first reaction was that it would be a pretty badass flange but saw no real problem with it. Then I...

    Max allowed thickness of seamless pipes

    When it comes to tolerances of the nominal thickness of a pipe, most pipespecs have this text: "The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified." So how much thicker than the nominal thickness is the pipe allowed to be?

    Detached centre lines in drafts

    Ok so this is the case: I have placed "Centre line By 2 lines" in draw in view in the draft. Made some changes in the part file and saved. Update views in draft And of course the result becomes:"Annotation (center line) detached" :-) So my question is: Has someone found a way to reattach the...

    New issue of ISO 7005-1 in the works

    I just saw that a review process has started on the ISO flange standard. Does anyone know what changes to expect? http://www.iso.ch/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=42467&showrevision=y&scopelist=PROGRAMME /Pontus

    Error in ASME I - Fig. PG-32

    Well, well a conversion error apparently found its way through the ASME reviewing process. In note c, the SI calculation gives a d which is over 8.5 times higher than its us customary counterpart. the right SI formula should be something like: d=8.08[Dt(1-K)]^1/3 NOT d=69.9[Dt(1-K)]^1/3 /Pontus

    B16.25 fig. 4

    This is something that has been up to debate here at work recently and it would be nice if any of you code gurus out there could give a definitive answer. The question was: Does the "C" dimension really apply to fig. 4 or can "B" be used as ID of the welding end? And some of the reasoning...

    External pressure on an ellipsoidal head ASME VIII div 1 (UG-33-1b)

    I have run into a little problem. I am supposed to calculate a formed head of a semi ellipsoidal shape that is under a external pressure. This is my first time doing this calculation so this might be a really stupid question, but anyway: I have followed the steps and arrived in subpart 3 of ASME...

    ASME Section I, PG-32.1.2

    Hi everybody! I have a short simple question for today. The factor "t" is described as: actual thickness of the shell. So which is the definition for "actual thickness" of a seamless pipe? Should "t" be entered as the nominal wall thickness or should I use the minimal wall thickness. Because...

    Code case about WB36 material

    Hi everybody! I have heard rumors that there is an ASME case that allows the EN material WB36/15NiCuMoNb-5-6-4 (1.6368) to be used in an ASME installation, can anyone confirm this? If this really is the case, what max allowable stress values should be used in an ASME VIII, div 1 application...

    pressure seal bonnets acc to ASME B16.34

    Hi! I'm going to design a valve acc to ASME B16.34, so how can I calculate the P.S.B. on the valve? I have only found a way of calculating bolted bonnets in B16.34, so is there another ASME standard out there that has a way of calculating pressure seal bonnets? There is a great calculating...

    About X10CrMoVNb9-1 (EN 10222-2 )

    Hi! My question is short and simple: To what material group does X10CrMoVNb9-1 belong. The material is not listed in either EN-1092-1, ISO-7005-1 or prEN-12516-1 so if someone has any bright ideas, I would apreciate the help Thanks Pontus

    Which ASME VIII guidebook should I choose?

    Hi! I'm thinking about buying a guidebook for ASME VIII div 1 and I'm choosing between the following two: Guidebook for the Design of ASME Section VIII, Pressure Vessels by James R. Farr & Maan H. Jawad CASTI Guidebook to ASME Section VIII Div.1 - Pressure Vessels by Bruce Ball & Will Carter...

    Spherical bodies with do/di>1,5 acc to prEN 12516-2

    The code doesn't state any way of calculating sperical bodies with do/di>1,5 It would be great if spheres with do/di>1,5 was considered "thick enough" and no calculation was required. Haven't found anything in the standard to support this however, so every time that I have had a case...

    ASME B31.3 304.1.2(b) What to do!?

    What do I do if the thickness i higher than D/6? The design code doesn't specify any equations for that, only that special considerations needs to be made. I'm more used to B31.1 and that code doesn't have any restrictions like this one(that I know of) Thanks Pontus

    Designing thick circular shells at high temp acc to ASME I PG-27

    Acc to ASME I, if the thickness of the shell is greater than one-half of the inside radius then the calculation should be carried out acc to PG-27.2.3 which says: The maximum allowable working pressure for parts of boilers of cylindrical cross section, designed for temperatures up to that of...
