Core advantages of the product

1. Strict material selection, excellent safety performance

The main body of the sulfur hexafluoride steel cylinder is made of high-quality carbon steel/alloy steel specifically designed for pressure vessels. After strict material testing and mechanical performance testing, it has high strength, high toughness, and excellent corrosion resistance. In response to the chemical characteristics of SF₆ gas, the inner wall of the cylinder has undergone special passivation treatment, effectively preventing chemical reactions between the gas and the cylinder wall, avoiding the influence of gas purity, and greatly improving the service life of the steel cylinder. In addition, sulfur hexafluoride steel cylinders are equipped with professional safety accessories (safety valves, pressure gauges, rupture discs, cylinder valves), all of which have been verified and certified by authoritative institutions to ensure stable pressure, safety and controllability during storage, transportation and use, and to avoid safety risks from the source.

2. High precision manufacturing process, excellent sealing performance

Sulfur hexafluoride steel cylinders are manufactured using advanced spinning and seamless welding processes, with uniform wall thickness, compact structure, and no welding defects. They undergo multiple strict testing processes such as hydrostatic testing, airtightness testing, and radiographic testing to ensure that the cylinders are leak free. The bottle valve adopts a dedicated high sealing performance valve, matched with customized sealing gaskets, with a sealing level that meets the industry's high standards. It can effectively prevent SF ₆ gas leakage, ensure gas purity, and avoid environmental impact and resource waste caused by gas leakage.

3. Diverse specifications to meet diverse needs

According to the gas consumption requirements of different industries and scenarios, we provide a variety of specifications of sulfur hexafluoride steel cylinders, with capacities ranging from 4L, 8L, 10L, 40L, 50L and other conventional specifications. We also support customized special volume steel cylinders. The working pressure of sulfur hexafluoride steel cylinders is adapted to SF₆ gas storage standards (commonly 15MPa, 20MPa), and can match SF₆ gases of different purity levels (industrial grade, electronic grade, high-purity grade). It is widely suitable for various application scenarios such as power equipment insulation, electronic semiconductor manufacturing, metal smelting protection, meteorological detection, etc.

4. Convenient design, easy to use and maintain

The appearance of sulfur hexafluoride steel cylinders adopts standardized spraying technology, with uniform wear-resistant and rust resistant coatings. The cylinder body is clearly marked with key information such as product specifications, working pressure, manufacturing date, inspection cycle, warning signs, etc., making it easy for users to identify and manage. The bottom of the bottle is designed with an anti slip base, which is stable and not easy to tip over; The top is equipped with standard lifting rings for easy lifting and handling. At the same time, we provide comprehensive product user manuals and maintenance guidelines, with clear inspection cycles for steel cylinders and simple maintenance processes, significantly reducing user usage and maintenance costs.

 Safe use and precautions

1. Sulfur hexafluoride steel cylinders should be stored in a cool, dry, well ventilated place, away from sources of fire, heat, flammable and explosive materials, avoid direct sunlight, and the ambient temperature should not exceed 60 ℃;

When handling sulfur hexafluoride steel cylinders, they should be loaded and unloaded gently, and collision, knocking, and rolling are strictly prohibited to prevent damage to the cylinder body; Special lifting equipment should be used during hoisting, and direct hoisting of bottle valves is strictly prohibited;

3. Strictly follow the operating procedures when using, slowly open the bottle valve to prevent sudden pressure rise; During use, the pressure gauge reading should be closely monitored, and overpressure use is strictly prohibited;

4. The gas inside the sulfur hexafluoride steel cylinder should not be completely exhausted, and a residual pressure of not less than 0.05 MPa should be retained to prevent air from entering the cylinder and contaminating the gas;

5. Sulfur hexafluoride steel cylinders should be inspected regularly, and cylinders that exceed the inspection period are strictly prohibited from use; If any abnormal conditions such as corrosion, deformation, or leakage are found in the sulfur hexafluoride steel cylinder, it should be immediately stopped from use and professional organizations should be contacted for handling.
