A pressure vessel is a container that can hold pressurized gas or liquid in many industrial and commercial applications. These containers can be made of materials such as steel, aluminum, stainless steel, plastic or glass.

Pressure vessels are often exposed to a source of pressure during processing or storage, and this pressure changes the properties of the gas or liquid in the vessel. For example, these containers can be boilers, tanks, silos, pipelines, pressure cylinders, bottles and other similar containers.

Pressure vessels are used for many purposes in industrial facilities. Some of these are those:

Storage: Pressure vessels can be used to store materials such as liquids or gases. These containers can also be used where these materials may be hazardous or corrosive.

Processing: Some industrial processes require materials to be processed under a pressure or to increase reaction efficiency. Therefore, pressure vessels may be required for these processes.

Transport: Pressure vessels can be used to transport liquids or gases. These containers can be used for the storage and distribution of gases transported from large facilities such as oil or gas pipelines.

Because pressure vessels contain hazardous materials, they must be strictly inspected and maintained for safety. There are strict rules and regulations designed for the safe use of these containers and it is important to follow these regulations.
