In the pressure vessel design SW6-2011, how should two reinforcement rings be entered?

I would like to ask the experts: in the pressure resistance design SW6-2011, if there are two reinforcement rings, how should they be entered? And for external pressure calculations based on volume, how should the length be entered? Thank you
If a cylinder is subjected to external pressure due to its excessive length, then the calculation length for that external pressure must be taken into account; if one length is not sufficient, two lengths need to be considered. When calculating, you need to do it separately: calculate the quadratic value, or determine the length of the longest section by considering the external pressure.
Since the external pressure lengths are different, the sum of half of the calculated lengths of the cylinders on either side of the reinforcement ring is also different. The wall thickness required to add two rings is generally thinner than that for one reinforcing ring.
