What is gas cylinder?

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.
The term cylinder in this context is not to be confused with tank, the latter being an open-top or vented container that stores liquids under gravity, though the term scuba tank is commonly used to refer to a cylinder used for breathing gas supply to an underwater breathing apparatus.

What are gas cylinders made of?

Gas cylinders can be made from aluminum, steel, alloys, and composite materials. Mechanical strength, corrosion resistance, and impact resistance are critical factors in determining which material is used.

Carbon fiber composite cylinders can be very light due to the high tensile strength of carbon fiber, but are more difficult to manufacture.

What is the pressure in a gas cylinder?

There are three major groups of compressed gases stored in cylinders: liquefied, non-liquefied and dissolved gases. In each case, the pressure of the gas in the cylinder is commonly given in units of kilopascals (kPa) or pounds per square inch gauge (psig). Atmospheric pressure is normally about 101.4 kPa (14.7 psi)

What is the capacity of oxygen cylinder?

It has an interior capacity of 26.73 liters. Therefore, 26.73 liters and 2200 psi. Therefore, 14.7 psi is the pressure at which the oxygen will be used.

Cylinder Sizes and Safe Temperature Regulation
When the temperature drops, maintaining optimal pressure in a liquefied gas cylinder can be incredibly difficult. Cold external temperatures prevent the liquid from vaporizing, which makes your gas cylinders unusable because of low pressure.
No matter what specialty gas you use – and regardless of the size you need – it is important to keep safety practices at the forefront of your mind. If your high-pressure cylinders are handled roughly or allowed to reach high temperatures without proper regulation, they are at risk of exploding without warning.
