Regarding the ear-type support JB/T4712.3, I have two questions: ①Is the formula in P106 incorrect? Should b2 be changed to (b2+2*δ2)? There are 7 letters in the formula, and the meanings of the 8 letters are indicated below. ②An ear seat B4 was calculated: diameter 1000, internal pressure 1.3, effective thickness 6.7. A line is drawn in the table on page P82 of Table B.1 – how should this be determined?

Calculate the local stress directly! It’s indeed inconvenient to need bending moments in this schedule.
