a pressure vessel for storage
A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.

Storage vessels/tanks are simple vessels used for storing liquids, solutions or pharmaceutical raw material and other chemicals.
These general purpose vessels made of stainless steel, fibre glass, titanium, galvanised steel etc.
and are used by a number of industries to store various substances and solutions.
Storage vessels/tanks can either be horizontal or vertical in their orientation.
Horizontal storage vessels are generally mounted on stands or saddles and have a access hatch either on the bottom or on the top.
Vertical storage pressure vessels are erected vertically and usually have access ports on the bottom.
These specialised vessels can either be placed above or below ground, depending on the construction of the storage facility.
The wall thickness of the vessel determines the application and the use of the vessel, while single wall storage vessels can be used for general applications, double walls vessels are generally used for high pressure considerations.
