1. What is the color of the oxygen cylinder?
Oxygen cylinders are high-pressure containers used to store and transport oxygen. They are generally made of hot-stamped and pressed alloy structural steel. Cylindrical in shape, there are many common pressure vessels such as gas bottles, including hydrogen bottles, nitrogen bottles, acetylene bottles, etc. They have similar appearances and are generally distinguished by color. So what is the color of oxygen bottles?
Generally speaking, the body of the oxygen cylinder will be painted sky blue, and the word “oxygen” will be marked with black paint. The shoulder will be stamped with working pressure, test pressure, volume, weight and other information. It is used for Distinguish other cylinders.
2. Why are oxygen tanks blue
Oxygen tanks are generally blue to distinguish them from other gas bottles, so why are oxygen bottles blue? Woolen cloth?
It is understood that oxygen is stored in oxygen bottles, and when the temperature of oxygen drops to -183°C, it will be converted into a liquid state, and liquid oxygen is light blue, so the industry regulates various gases When standardizing the color of the cylinder, this feature was used for oxygen, and the color of the oxygen cylinder was set to blue.
However, it should be noted that although the oxygen bottle is blue, it does not store liquid oxygen, but gaseous oxygen under high pressure. In addition, not all gases specify the color of their cylinders based on the color of the liquid when they turn into liquids. For example, liquid nitrogen is colorless and transparent, but nitrogen cylinders are black. In fact, the principle of determining national standards is to adopt a method that can make everyone more intuitive on the basis of maximum differentiation.
