High pressure oxygen cylinder
Oxygen cylinders are high-pressure containers for storing and transporting oxygen. They are generally made of alloy structural steel by hot punching and pressing, and are cylindrical. Used in hospitals, first aid stations, and nursing homes.
The shoulders of the cylinders are marked with steel stamps of working pressure, test pressure, volume, weight, and other information. The surface is painted sky blue, and the word “oxygen” is written in black.
The unit of measurement for the size of a medical oxygen cylinder is a volume unit: liter
The size of a medical oxygen cylinder is calculated in liters. A 10-liter cylinder means that it can hold approximately 10 liters of water, while a 40-liter cylinder can hold 40 liters of water.
There is approximately 135 to 150 atmospheres in a full cylinder.
The larger the volume, the more oxygen it can hold.
The pressure in a full cylinder is the same, regardless of the volume of the cylinder.
That is to say, whether in a 4 liter, 10 liter or 40 liter bottle, the pressure is the same when the bottle is full. If the pressure is the same, the volume determines how much oxygen the bottle can hold.
