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.
Since glass-fiber-composite materials were used to reinforce cylinders, there are various types of construction of high-pressure vessels
1. Metal only. Mostly seamless forged metal. But for lower working pressure, e.g., liquefied butane, there are welded steel vessels, too.
2. Metal vessel, hoop wrapped with a fibre composite only around the cylindrical part of the "cylinder". (Geometrically there is a need for twice the tensile strength on the cylindrical region in comparison to the spherical caps of the cylinder.)
3. Thin metal liner (that keeps the vessel tight, but does not contribute to the working pressure) fully wrapped with a fibre in matrix material.
4. Metal-free liner from plastics, fully wrapped with fibre material. The boss, the centre of the head(s) of the cylinder is still from metal and includes the thread for the valve.
