Sulphur Hexafluoride SF6 is a colorless, odorless, non-toxic, non-flammable gas at room temperature and pressure. The molecular weight is 146.05 and the gas density is 6.0886g/L under standard conditions. Sulphur Hexafluoride SF6 gas is very stable and is not easy to react with other substances even at high temperatures.
When using Sulphur Hexafluoride SF6, the operating environment should be kept ventilated, leakage is strictly prohibited, and oxygen-deficient air should be avoided.
Sulphur Hexafluoride SF6 is a good gas insulator and is widely used for arc extinguishing insulation of electronic and electrical equipment. In the smelting and casting process of non-ferrous metals, sulfur hexafluoride can also be used for degassing and purification of aluminum and its alloy melts.
Sulphur Hexafluoride SF6 is stored in seamless steel cylinders. It is a liquefied gas in the cylinder. The cylinder should be stored in a classified manner during transportation, storage, and use, and it is forbidden to be close to open flames and heat sources.
The inspection cycle of Sulphur Hexafluoride SF6 seamless cylinders is 5 years, and the maximum service life of the cylinders is 30 years. All expired cylinders must be sent for inspection before they can continue to be used, and they must be scrapped after reaching the maximum service life.
