    UHX design conditions

    Dear all, I've got a question about the different design conditions one should considder to calculate a heat exchanger with fixed tubesheets. Sometimes the customer defines the design conditions theirself, but for quotation requests most of the times no conditions are predefined. Depending on...

    Open source ASME calculation program

    Short intro: Last year, I wanted to learn C#. And what's better to learn a language then programming something 'usefull', so I started programming on a simple ASME calculation program. Nothing fancy with 3D and so on, but plain calculations in a nice (Windows) environment, with the ability to...

    Dynamic polar array question

    Hello, We are currently testing the use of dynamic blocks to improve our autocad system. We've been testing all functionalities and find it very interesting, but there is 1 part that we do not understand. Why is the 'polar array' in dynamic blocks different from drawing 'normal polar arrays'...

    Why does a selection trigger the calculation state?

    Hello, I have a spreadsheet with many calculations (ASME UHX calculations). Because of the number of calculations, it takes 10 to 20 seconds to see the complete results. Because of it's slowness, I turned automatic calculation off, and now I press a button to force calculation. The reason...

    How to make real linked cells, not with formulas?

    I have an excel workbook with different sheets. On 1 sheet, I calculate the thickness of a fixed tubesheet according to TEMA, on another sheet I do the same for ASME-UHX. All of the data that is used for both calculations is 'linked' with a formula ( ='sheet1'C2 for example ) But, there is...

    axis calculation

    I'm calculating an axis for the wheel of a rotator to rotate large and heavy pressure vessels. (up to 500 tons) Basically, it's nothing more then an axis, supported by 2 bearings, and a large wheel in the center. The wheel is in fact a custom build part, made by welding 3 circular plates (20mm)...

    differences between charts and graphs

    Did anybody noticed the differences between the charts and the graphs of several material groups? (we use the metric ones) I even think there are some errors in the charts. We use the charts in our excel calculation sheets, and we came across some deviations. Does somebody else uses the...

    Nozzle loads

    On a vertical tower we have several nozzles, let's say 30. On every nozzle we have loads (forces and/or moments) WRC can calculate the effect of these loads to make sure the nozzle is strong enough. But, how are all those loads influencing the vessel design? Because of all the different...

    Disasu software help

    Are there any Disasu users over here? We really want to test this software, but we cannot get it up and running. It seems it doesn't like Windows Vista? On our XP machines, we managed to get some more out of it, but the registering for a demo version keeps on crashing (server problems?) There...

    Appendix 1-7 calculation

    Hello, I do not understand the definition of the limits stated in appendix 1-7 of the ASME code. It seemes there are 2 different limits of reinforcement used for calculation of formulas (1) and (2) of 1-7(b), and formules (3)-(4)-(5) of 1-7(b) which also differ from the limits used in UG-37. I...

    Some Compress questions

    While evaluating Compress, I came accross some issues, which I think are not 100% according to ASME... But, I'm pretty new at this, so I might be wrong too. (1) A nozzle in a head: To calculate the minimum head thickness, the corroded values of Di and h are used, and the thickness is calculated...

    How to interpolate in table G

    Hello, I'm trying to understand how to interpolate values from table G (Do/t - L/Do to A-value) I have the tabular version in an excel sheet, and I'm trying to calculate value A from input Do - t - L The code-part is not a problem, but the way to interpolate brings up questions. The excel...

    ASME binders

    Not sure where to put this question... We use the ASME books pretty intensive, and they start to wear very quick now. The ASME 2004 version was provided with a very decent binder, the 2007 version came with a light version. Our old 2004 binders look better then some 2007 binders. Our problem...

    ASME Div2 version

    Does anybody knows when we might expect the div2-rules of ASME VIII ed07 add08 included in compress? I thought the 'old' div2 rules are limited in use until june/july this year? thanks! Jeroen.

    ASME Code Case 2286 limitations

    While looking into the ASME code case 2286, I was wondering if there are any limitations. I can only find direct information about cylinders, cones, speres and formed heads. Can I presume this code case is also allowed for tubes? More detailed: is it allowed to apply this code case for heat...
