Seeking Chinese materials: calculation of double-shell plate strength
Thread Content
I searched on this forum; regarding the strength calculation for double-wall plates, it is said that the relevant information can be found in TEMA. However, TEMA is entirely in English, and there is no Chinese version available. I wonder if anyone has any Chinese materials on this topic. This post was last edited by jia717 on 2009-3-29 at 17:27
Bro, when using the TEMA standard to calculate according to national standards, the spacing between the double tube sheets is usually relatively large. But if SW6 is used, it’s more complicated; however, safety should still be ensured! With SW6, many calculations are required, and what’s worst is that both Chinese and English versions are needed – oh my god! I’ve done several projects involving double tube sheets and I’m almost driven crazy! The main difficulty lies in the manufacturing process itself; this shows the importance of manufacturing techniques. Anyway, I’m too lazy to think about it. It’s really difficult for workers to ensure no leaks, as they have to be extremely careful
If it is designed in accordance with national standards, take a look here; using SW6 for the calculation of the tube sheets in double-tube-sheet heat exchangers might be helpful: http://bbs.hcbbs.com/thread-273798-1-1.html This post was last edited by jia717 on 2009-3-30 at 17:21
Just create a calculation table by yourself; what’s the need to use this or that!
If I had the information, I could of course create a table by myself; it’s just that I don’t have the information
There are many explanations on the forum regarding the calculations for double-wall plates. When performing these calculations, the same methods used for the tube side and shell side are applied; the only difference is that the area where there is an interruption in between is first calculated as part of the tube side, and then again as part of the shell side. That’s roughly how it works. SW6 or LANSYS can be used for this purpose. The original poster can search on the forum – there are many papers and materials available related to double-wall plates!
