Seeking guidance on the design specifications for rectangular pressurized vessels at 40 KPa
Thread Content
I have a question: for a rectangular container under a pressure of 40 KPa, which does not meet the requirements of GB150 nor NB/T47003.1, are there any other design standards available? Thank you!
It is designed according to the standards for pressure vessels at normal pressure, so there’s no problem with that.
Atmospheric pressure rectangular containers need to be connected to the atmosphere; since mine has an internal pressure of 40 kPa, is that okay?
You can calculate it using the non-circular container function in SW6 software
During design, you can use angle steel to reinforce the box, which can also reduce its thickness. Generally, the bottom plate of the box is a bit thicker than the thickness of the box itself. Another point is that when designing the box, its four corners should be made into rounded corners, and the radius of these rounded corners can be set to R200 or some other value.
Why is the bottom plate of the box slightly thicker than the thickness of the box itself? Is there any evidence?
