Calculation of large openings under external pressure
Thread Content
There is now a calculation issue related to large openings under external pressure; the size of these openings exceeds the limits specified at 150. We plan to use the AD codes for the calculations, but I’m still not entirely confident about it. I wonder what good suggestions everyone has in this situation. :)
Why not use ASME? Let’s do some analysis, design, and calculations instead
If it exceeds 150, can’t it be calculated using the \"Strengthening Calculation for Large Openings\" specified in HG20582? Why use AD and ASME still?
This statement is fairly accurate; as mentioned earlier, analytical design is used, and the results of such design may not be entirely reliable, but there should be no major problems. Using a dual-normalization design is a bit troublesome, but to be sure, one has to resort to it. Practice has shown that the AD specification design is quite radical.
The calculation for HG20582 with large openings is intended for internal pressure; it cannot be used for external pressure. So, analytical design calculations are still necessary, or reference to standards such as ASME should be used. ] This post was last edited by Wen Bing on 2007-11-27 at 14:49 [
