The design of U-tube heat exchangers (with double tube sheets) requires the use of stress analysis methods for accurate calculation. Some units do not have this capability; in order to save around 15,000 yuan, they opt to use SW6 for calculations. I read some papers and found that there is a suspicion of plagiarism between them, and the views in some of the papers are incorrect. For example, in the design of U-tube heat exchangers (with double tube sheets), some suggest calculating according to types e and f as specified on page 27 of standard GB151, and taking the larger value ； Some say that it should be calculated separately for fixed tube sheets and U-shaped tube sheets. I can’t figure out which one is more reasonable
