Calculation of flat covers
Thread Content
There is currently a pressure-free container with a cylindrical body whose diameter is 5 meters and height is 3 meters; it features flat lids at the top and bottom. The upper flat lid has a pipe connection of DN500, equipped with a DN500 pipe flange. This pipe flange is connected to a pump via studs and nuts, and the weight of the pump is approximately 3 tons. I would like to ask those with more experience: how should the strength of this flat lid be calculated? Also, if the cylinder diameter is set at 5 mm, will it be able to support the flat cover and the weight of the pump? How should this be considered?
1. Connector with reinforcement ring 2. Channel steel added outside the reinforcement ring (2 in each X and Y direction) 3. Reinforcement plate for the connector 4. If the pump is placed horizontally, additional channel steel must also be considered
A significant amount needs to be added here; I think it’s fine. The pump can be considered as a concentrated load, and the reinforcing ribs can be treated as beams for simple calculations
