What should you pay attention to when connecting quick-open containers with hinge bolts?
Thread Content
For containers that use articulated bolts to connect equipment flanges, in addition to calculating the flange to be qualified, what other calculations should be made? Do the pins and lugs of the fixed joint bolt need to be calculated? Is there any restriction on the range of operating pressure etc. for this structure?
I want to know too! Some time ago, I made a random comparison based on the force on the cover and the force on the pin, but I don’t know if it’s right! :$ :loveliness:
It is best to use stress analysis and calculation. If you do not have this ability, design according to standards (such as JB581-79 Rotary Dome Flat Welding Flange Quick Manhole, etc.) or based on comparable structures that have been put into use.
The fixed joint bolts must be calculated, and there are MY value requirements when selecting gaskets.
If there is no standard reference, of course every step must have a calculation basis, and the operating pressure cannot be high.
There is a calculation on the forum based on the second edition of chemical equipment component strength calculation.
Do you have this book? Or where can I find it? Thanks
