A calculation problem for pressure vessels under external pressure
Thread Content
When designing pressure vessels under external pressure, if the value of A is not listed in the chart (it lies beyond the far right edge of the chart), how should the value of B be determined?
In my opinion, when the value of A falls on the left side of the curve and it is not possible to determine the value of B, this is due to limitations in the diagram size that prevent the full range from being shown; in such cases, calculation should be carried out using formula 6-2 from GB150； When the A value is beyond the right side of the curve in the graph, the B value is determined using the endpoint value of the curve.
What was said upstairs is correct: when the A value exceeds the left limit, it is calculated using the formula; when it exceeds the right limit, the value at the right endpoint is used
The most effective way is still to use calculations, because graphs are also based on formulas
Reply to 4# GK800920: It’s not calculated using a formula; it would be convenient if it were.
