Calculation of rectangular pressure vessels
Thread Content
For a rectangular pressure vessel with dimensions of 20 mm in length, 125 mm in width, and 1000 mm in height, operating under a pressure of 25 MPa at 380°C, and with openings made on its upper and lower surfaces, the cross-sectional properties can be calculated using GB150-2011. But how is the wall thickness for these upper and lower surfaces determined? Is it calculated by viewing it from another angle as a cross-section? It should still be calculated based on end caps or flat lids.
Length: 20 mm, Width: 125 mm, Height: 1000 mm, Pressure: 25 MPa, Temperature: 380°C. Are you sure you want to make it a rectangular pressure vessel? Why not make it round?
The wall thickness of rectangular pressure vessels is calculated using formulas; you can find them in the appendix.
This is a specific use for special instruments; they can only be designed in this way. As a result, we don’t know how to handle their upper and lower end caps, and we would like some advice on this
I carried out the calculations by referring to the appendix in GB150-2011; the cross-section was set at 20*125 mm. However, there are no calculation formulas for the upper and lower covers, and the formulas available for those covers fall outside the applicable range, so I’m not sure how to proceed. If I were to assume a size of 125*1000 mm for the covers for the purpose of calculation, the resulting structure would be too thick
You didn’t look at the standards carefully; you should have understood what each standard entails before proceeding.
#Reply quickly with # here. Hello, I’m a student. Do you have any drawings for the rectangular pressure vessel you designed? Could I take a look at them? I also want to design a rectangular container as a reference; I study * and use it
The appendices to GB/T150 contain design calculations for rectangular pressure vessels, which are applicable to internal pressure conditions. At the same time, in SW6, calculations can also be carried out according to the appendix of GB150. However, the calculated value is relatively high. As I understand it, it is possible to use different cross-sections for the calculation of rectangular pressure vessels, and then take the largest value as the final design thickness.
