What type of cylinder is referred to as a low pressure cylinder?

A low-pressure cylinder is specifically designed to contain gases or liquids at pressures that are below a certain threshold, typically around 15 psi and below. These cylinders are constructed to withstand lower internal pressures, which allows for a safer operation in environments where high pressures are not necessary or practical. They find uses in a variety of applications, such as in certain types of fire extinguishers or gas storage, where maintaining a controlled and safe pressure is essential.

Other types of cylinders, like high-pressure cylinders, are built to handle significantly larger pressures, and their design, materials, and safety features differ considerably from low-pressure cylinders. Gas-filled cylinders can refer to a range of pressure types but do not specifically denote low-pressure conditions. Meanwhile, a standard cylinder may imply a generic use without specific reference to pressure classifications, so it does not accurately define the low-pressure context being discussed.
