Seeking advice on input for internal and external pressure calculation in SW6
Thread Content
The design pressure is -0.1 MPa, the temperature is 100°C; the diameter of the cylinder is 3600, and its length is 7200. It has elliptical end caps at both the top and bottom. If four reinforcement rings are to be designed, how should this be entered in the boxes shown in the diagram? Could someone with expertise give some guidance?

The depth of the end cap is 900, and the length of the straight sections is 40. The four reinforcement rings are divided into 5 sections in total. (2*900/3+40*2+7200)/5,
Check GB150.3, calculate the total external pressure calculation length, and then determine the external pressure calculation length for sw6 based on the location of your reinforcement rings.
The second floor is the correct answer; the length for calculating the external pressure on a cylinder is the distance between the two rigid supports on the cylinder.
On the second floor, under ideal conditions, it’s like this. If there are large openings on the cylinder, or for some other reason the reinforcing rings cannot be evenly spaced, the data should be entered based on the maximum distance between any two adjacent reinforcing rings.
