Why Are Compressor Tanks & Gas Containers Round?

In summary, the conversation discusses the theoretical background of the shape of compressor tanks and gas carrying containers. It is explained that these tanks are typically round in shape to avoid stress concentrations and discontinuities at the corners. This is because a flat plate, pressurized on one side, will have bending stresses that are inefficient in distributing the forces due to pressure. Cylindrical and rounded sections are preferred because they are only in tension, allowing the entire wall thickness to contribute to resisting forces. The conversation also mentions the aesthetic appeal of circular shapes over square shapes.

Dear all
I need theoretical backround regarding shape of the compressor tanks or tanker lorries as well as gas carrying containers .

Why such are round shape instead of rectangle or square?

Any papers ,references sites are welcome

Thanks
Prakash

Mostly to avoid stress concentrations/discontinuities at the corners.

A flat plate, pressurized on one side, will have bending stresses in it, which is a very inefficient way of distributing the forces due to pressure.

Cylindrical and rounded sections are in tension only, so the entire wall thickness is contributing to resisting forces generated by the pressure.

a square tank

:yuck: sup!
i will agree. the reason is most definently stress concentrator that are created by sharp corners. take a motor shaft for example, the most likely place for the shaft to fail is at the keyway bcoz of the sharp edges due to machining of the shaft.
and ooohhh ja, circles look betta then squeres:smile::smile::smile:
 

1. Why are compressor tanks and gas containers round?

Compressor tanks and gas containers are round because it is the most efficient and cost-effective shape for containing pressurized gases. The round shape allows for equal distribution of pressure, making the tanks and containers more stable and less likely to rupture.

2. Are there any other shapes that are commonly used for compressor tanks and gas containers?

Yes, cylindrical and spherical shapes are also commonly used for compressor tanks and gas containers. However, these shapes are more expensive to manufacture and may not be as efficient as the round shape.

3. How does the round shape of compressor tanks and gas containers affect their performance?

The round shape of compressor tanks and gas containers allows for better flow and distribution of gases. It also helps to prevent stress points, which can weaken the structure and increase the risk of leaks or ruptures.

4. Are there any safety benefits to using round compressor tanks and gas containers?

Yes, the round shape of these tanks and containers makes them less likely to fail under pressure, reducing the risk of explosions or other accidents. It also allows for easier handling and transportation.

5. What materials are commonly used for round compressor tanks and gas containers?

Common materials used for round compressor tanks and gas containers include steel, aluminum, and composite materials. These materials are strong and durable, and can withstand high levels of pressure without deforming or breaking.
