On the deflection of horizontal vessel shells
Thread Content
Are there any standards specifying how to control the barrel deflection of longer horizontal containers? How to calculate it?
None of the places state it clearly; everything is vague.
Is there any rule? Are you referring to straightness?
The stability of the equipment during lifting must be taken into account
The barrel deflection of longer horizontal vessels should be controlled by increasing the number of saddles.
Finite elements are quite practical for analyzing complex stress conditions
So what determines whether to increase the number of saddles?
I haven’t come across any regulations; personally, I think as long as the strength and stiffness are sufficient and no danger is posed, that’s fine.
The requirement that horizontal containers have no deflection can be ensured through multiple saddles.
All pressure vessels are manufactured in accordance with standards. As mentioned above, could you list those standards? I’ll go and check them as well
