Difference between pressure vessel and cylinder as per gas cylinder rule

Question

Accepted Answer

Pressure vessels are designed to hold liquids or gases at a pressure different from the ambient pressure, while cylinders are specifically designed to store gases under pressure.

Pressure vessels are designed to withstand high pressure, typically used in industrial applications such as boilers, reactors, and storage tanks.
Cylinders are portable containers used to store and transport compressed gases, such as oxygen tanks or propane tanks.
Gas cylinder rules regulate the design, construction, and maintenance of cylinders to ensure safety.
Pressure vessels have thicker walls and are usually stationary, while cylinders are lighter and portable.
Examples of pressure vessels include air compressors, hydraulic reservoirs, and pressure cookers.
