Is there a problem with the size of the cylinder takeover?
Thread Content
When designing sub-cylinders, it is often encountered that the outer diameter of the sub-cylinder nozzle is too large, exceeding the allowable opening range of GB150 conventional design, so we have to increase the cylinder diameter! It should be possible to exceed the scope of conventional design, and the stress analysis method should be used for reinforcement calculations. In actual design, it is always uneconomical to only consider the conventional design opening range and then increase the cylinder diameter. Dear friends, have you encountered the same problem or are you confused?
You can use the analytical method, but you can't use the pressure area method.
Use the analytical method. If it fails, use local stress analysis. Do not use the pressure area method to calculate, because the large opening bending moment plays a big role, and the pressure area method has problems.
Then increase the cylinder diameter! !
Now both 20583 and SW6 involve the pressure area method.； What exactly is the problem? :handshake
Purchase thick-walled pipes under the condition that the inner diameter of the cylinder is greater than twice the opening diameter.
I'm afraid it won't work for pressure vessels.
I have also heard that GB150 does not recommend using the pressure area method to calculate opening reinforcement.
Now, it is very convenient to use SW6 to calculate the analysis method
Is there any specific source: handshake
