When using SW6 to perform reinforcement calculations for openings in heads, the message “Internal pressure check for the pipe connection fails; reinforcement calculation for the opening cannot be carried out” appears. Seeking help from experts: dizzy:

For container plates, there is no Q345R with a value below δ8; use SW6 for calculations. If the stress at the head openings is not sufficient, take the nominal thickness of the head as δ8 and try again, or consider changing some of the parameters.

The thickness is too thin; “thickness 3.5, corrosion allowance 3” ”； The effective thickness is only 0.5, and a negative deviation also needs to be taken into account ； The internal pressure check, of course, passes. Take over the thickening point.
Agree with what was said on the fourth floor: is such a large corrosion allowance really necessary?
It’s probably because the strength of the takeover itself is not sufficient
Reply to 6# zhaolei092: Well, the medium is brine, that’s why. . . The reason has been found – just increase the thickness of the Takeover: lol
Reply to 4# liushen203 :victory: It was quite successful. Remember that, 3Q~
