According to the risk factor analysis of Dewar bottles, Dewar bottles are used to install various tools for storing liquid and gaseous substances. These tools may be unfamiliar, but are used in industrial industries with more emphasis on personal safety. Therefore, Dewar bottle manufacturers will analyze the risk factor of Dewar bottles with you.
1. Boiling point of low-temperature liquids:
The boiling point of cryogenic liquids under 101.3KPa pressure: liquid nitrogen -196℃, liquid oxygen -183℃, liquid argon -186℃. Contact with the human body will cause serious frostbite to the skin and eyes. A small amount of low-temperature liquid leakage or pipe valve leakage, will absorb the heat of the surrounding environment, the leakage point will quickly frost, and in serious cases will freeze.
2. Expansion of low-temperature liquids:
Low-temperature liquids receive high heat from the surrounding environment or a large number of leaks to absorb the surrounding energy, and their volume will expand due to rapid vaporization. In 0 ℃ and 101.3 KPa pressure, 1L low-temperature liquid vaporization of gas volume of 674 L, oxygen for 800 L, argon for 780 L. Due to low-temperature liquid vaporization, the container or pipeline is prone to overpressure explosion.
3. Cryogenic liquid leakage:
In the environment around the cryogenic liquid storage tank, cryogenic liquid leaks after vaporization is easy to form a gas-rich area. If the concentration of nitrogen, argon and carbon dioxide is high, it is easy to cause asphyxiation injury. In addition, when the oxygen concentration is high, oxygen-rich damage will also occur.
4. Oxidation of low-temperature liquids:
Oxygen is a strong accelerant, with strong oxidizing properties. Liquid oxygen near combustible materials, easy to cause open flame combustion; contact with combustible materials, due to vibration, impact and other reasons easy to explode; mixed with combustible materials have the potential risk of explosion. Liquid oxygen can be attached to the fabric of clothes, which can easily cause flash and harm human body.
The above is the analysis of the risk factors of Dewar bottle. If you don’t know or need to buy Dewar bottles, refrigerant bottles and non-refillable bottles, please contact Dewar bottle manufacturers.
