Equipment design calculation sheet
Thread Content
I’m a beginner and would like to ask the experts here: can the calculation sheets generated using software in equipment design be used directly as the official design documentation? For example, can the calculation report generated by using SW6 for heat exchangers be used directly as a design calculation report? If it is a non-standard device, is it necessary to carry out the calculations oneself and produce a calculation report?
The calculation sheet produced by SW6 is recognized, right? If you calculated it directly using Sw6, I think it should be reasonable.
Thank you! I learned it, as I was just starting work – at school I would do the calculations myself and then use SW6 to verify them, while at the workplace I used SW6 directly to carry out the calculations and prepare the relevant reports. However, the equipment quality values in SW6 differed from those I calculated, which made me feel a bit uneasy: lol
Of course! Now, most conventional designs use SW6.
Mainly, I read a lot on forums saying that SW6 has various bugs, and I’ve encountered those issues myself as well. There were always problems with the material database I created; it took me a long time to figure things out. When the tube side was under negative pressure while the shell side was under positive pressure, I’m not sure why the design pressure for the tube sheet flanges was set to the pressure of the shell side, which is why I had some doubts.:)
What matters in a calculation document is not whether it was created using software or something else, but rather that the designer is responsible for the correctness and accuracy of the calculations
The SW6 software states that it is not responsible for the accuracy of the calculation sheets； The designer is responsible for the correctness and accuracy of the calculations.
SW6 is not responsible because the calculation sheet can be modified, but its calculated results are recognized.
Regardless of the calculation software you use, as long as the following three conditions are met, a calculation report can be produced and will be recognized: 1. the rationality of the technical assumptions in the program used; 2. the suitability of the program for the design in question； 3 The input parameters and output results used are for verifying the correctness of the engineering design. Currently, SW6 is recognized because it is convenient for engineers and technical personnel to use for calculations. Such professionals pay attention to the accuracy of entering the third parameter, but it is essential to first assess points 1.2 (which refers to what is commonly called model correctness) before conducting the calculations – this is a prerequisite!
