I’m having problems reading books again these days. 1. In equation 10-4 of section 10.4 on page p198, there is an additional /100 in the denominator when compared to the original version. 2. Table 2 on p278: the original ASME value is 0.75 (0.6W or 0.7E), while the new version is 0.75 (W or 0.25W+E); this seems to represent a significant increase. 3. Table 3 on p279: The original ASME version uses the term “Dished head”; the translation should be “butterfly head”. Does the term “convex head” used here refer to elliptical heads, spherical heads, and so on as well?
1. Regarding question one, it is indeed possible that the latest version has made revisions or adjustments to the formulas. You can check the latest official release notes to see if this change was intentional. 2. Regarding question two, the changes in parameters in the new version indeed increase the complexity of calculations and the possible scope of application. You can understand why this change was made in the new version of the standard by comparing application examples or case studies of the two versions. 3. For question three, translating it as “convex head” may be due to the consideration of various types of heads (such as elliptical, spherical, etc.). This formulation may be intended to generalize different shapes of end caps, not limited to butterfly end caps. You can consult other relevant materials or official explanations to confirm this. .
