This category features high-purity sulfur-hexafluoride (SF₆), certified SF6 cylinders, and engineered SF6 gas package solutions for utilities, OEMs, EPC contractors, and semiconductor manufacturers. As a professional industrial gas and pressure vessel supplier, we provide compliant filling, analytical verification, and export-ready packaging for global projects.
What Is Sulfur-Hexafluoride (SF₆)?
Sulfur-hexafluoride is a synthetic, non-flammable, chemically stable hexafluoride gas with:
- Extremely high dielectric strength
- Excellent arc-quenching performance
- Strong thermal and chemical stability
- Compatibility with high-voltage sealed systems
Because of these properties, SF6 gas is widely used as an electrical insulation gas in high-voltage transmission and distribution equipment, and as a precision process gas in electronics manufacturing.
Our SF6 Product Scope
1) SF6 Gas (Industrial & High Purity)
We supply compressed and liquid sulfur-hexafluoride in multiple purity grades:
- Industrial grade SF6
- High-purity SF6 (up to 99.999% upon request)
- Controlled moisture content for GIS applications
- Batch-level gas analysis reports
Every filling batch is tested for purity and moisture to ensure suitability for gas-insulated switchgear (GIS), circuit breakers, and sensitive semiconductor processes.
2) SF6 Cylinders
Our SF6 cylinders are manufactured according to recognized pressure vessel standards (such as ISO 9809) and undergo:
- Hydrostatic pressure testing
- Leak detection inspection
- Valve compatibility verification
- Traceable serial number marking
Available cylinder sizes include:
- 10L, 20L, 40L, 47L, 50L
- High-pressure configurations for utility projects
- Valve options for filling, recovery, and maintenance systems
All sulfur-hexafluoride cylinders are prepared for international transport with appropriate labeling and documentation (UN1080 classification).
3) SF6 Gas Package Solutions
For large-scale power grid and industrial projects, we offer engineered SF6 gas packages:
- Single cylinders for maintenance service teams
- Multi-cylinder bundles
- Tube skids for project supply
- Bulk gas coordination
- Palletized export packaging
These solutions are suitable for utilities, GIS manufacturers, high-voltage equipment OEMs, and gas service providers.
