The gas density of sulphur hexafluoride is approximately 6.17 kg/m³ and the amount of sulphur hexafluoride gas in a cylinder varies depending on the size of the cylinder.

1. What is sulphur hexafluoride?

Sulphur hexafluoride is a colourless, pungent chemical substance, chemical type SF6, which is mainly used in circuit breakers and transformers in electrical power systems to effectively reduce the size and weight of electrical equipment, and also helps to reduce the failure rate of electrical power systems.

2. What is the gas density of sulphur hexafluoride?

The gas density of sulphur hexafluoride is approximately 6.17 kg/m³, which means that the density of sulphur hexafluoride gas is approximately five times that of air. Bottle by bottle test

3. How much sulphur hexafluoride gas is in a bottle?

The amount of sulphur hexafluoride gas in a cylinder varies depending on the size of the cylinder. In general, the storage and transportation of sulphur hexafluoride gas requires the use of high pressure cylinders, which can range in size from small to large, 3L, 5L, 10L, 40L, etc. Depending on the pressure and temperature, the contents of a bottle of sulphur hexafluoride gas will also change. Taking a 40L bottle as an example, the content of a bottle of sulphur hexafluoride gas at 25°C and a pressure of 3 at MPA is approximately 25kg.

4. Summary

Sulfur Hexafluoride is a widely used chemical gas. It has a high density and must be stored and transported in high pressure cylinders. The content of a cylinder of sulphur hexafluoride gas varies according to the size, pressure and temperature of the cylinder. The content should be correctly estimated before use to avoid using too much or too little.
