SF6 Sulfur Hexafluoride
DSW Industry is one of the leading suppliers of calibration gases and specialty gases.
We are focused on high-quality specialty gases, gas handling equipment, and calibration gases.
Our products are used in various instrumentation applications, including those in the laboratory, energy industry, research and development, petrochemical, and refinery industries.
SF6 GAS CYLINDERS
All SF6 gas cylinders conform to applicable international (ISO), federal (DOT), and state regulations to ensure end-users never experience issues with transportation, handling, and environmental-related events.
DSW also provides six and sixteen SF6 Cylinder Storage Packs that offer the same efficiency as tonners but are easier to transport, manage, and use. Storage packs supply an efficient yet safe method of transporting cylinders between their gas delivery source, your workplace, or your gas supplier.
SF6 Cylinder Filling Process
As SF6 can be easily liquefied in a cylinder, its static vapor pressure remains consistent regardless of whether or not its contents have changed drastically. Therefore, bottles rated 300 PSIG may contain 100 or 10 pounds of the product depending on whether or not their contents have changed drastically over time. To accurately verify how much gas there is in a bottle, it is essential to monitor its weight while filling or emptying it – and use an accurately calibrated weighing device to avoid overfilling storage cylinders.
What is sulfur hexafluoride used for?
Approximately 80% of SF6 is used for electricity transmission and distribution. Medium and high voltage electrical equipment incorporates SF6 as an insulant around live electrical parts to help protect them against the electric current flow; additionally, it allows switches to turn it on or off quickly.
Sulfur hexafluoride is a synthetic fluorinated compound with a highly stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to date. Over 100 years, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un-degraded state for many centuries. Thus, a small amount of SF6 can significantly impact global climate change.
Formula of Sulfur Hexafluoride
SF6 or sulfur hexafluoride gas molecules are combined with one sulfur and six fluorine atoms. This gas was first realized 1900 in the Faculte de Pharmacie de Paris laboratories. In 1937, General Electrical Company realized that SF6 gas, i.e., sulfur hexafluoride gas, could be used as insulating material.
As one of the premier sulfur hexafluoride suppliers, we also specialize in providing other rare and specialty gases for industrial, commercial, and consumer uses at competitive prices. We offer SF6 as well as other specialty gases at highly discounted rates.
