As an accredited Sulfur Hexafluoride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | A sturdy, high-pressure steel cylinder with safety valve, labeled "Sulfur Hexafluoride, 10 kg", featuring clear hazard and handling instructions. |
| Shipping | Sulfur Hexafluoride (SF₆) is shipped as a compressed, liquefied gas in high-pressure steel cylinders. It must be labeled as a hazardous material and handled according to DOT and international regulations. Cylinders should be secured upright during transport, away from heat and ignition sources, and protected from physical damage. |
| Storage | Sulfur hexafluoride (SF₆) should be stored in tightly sealed, clearly labeled steel cylinders or containers specifically designed for compressed gases. Storage areas must be well-ventilated, cool, dry, and away from heat sources or direct sunlight. SF₆ containers should be kept upright, secured to prevent falling, and away from incompatible substances, such as strong oxidizers and moisture, to ensure safety and stability. |
