What type of container is typically used for high-pressure tanks?

Spherical tanks are typically used for high-pressure storage because their shape helps to evenly distribute stress across the surface of the tank, making them particularly effective at handling the internal pressures. The spherical design minimizes the risk of weak points that could lead to failure under pressure, which is critical when storing gases or liquids that are kept at high pressures.

This design allows for a stronger, more stable structure compared to other shapes, making it the preferred choice in industries dealing with compressed gases or volatile substances. Additionally, the spherical tanks can accommodate a larger volume of liquid or gas relative to their surface area, which is also advantageous for storage efficiency and safety.
