Core strengths
-High quality raw materials, sturdy and durable: Carbon dioxide steel cylinders are made of high-strength alloy steel to create the cylinder body. After multiple precision processes such as forging and rolling, they have excellent compressive strength and corrosion resistance, which can effectively resist the erosion of carbon dioxide gas during long-term storage and extend the product's service life. The surface of the carbon dioxide steel cylinder has undergone sandblasting, rust removal, and electrostatic spraying treatment, resulting in a uniform and dense coating that is not easily peeled off and can adapt to different environmental usage needs.
-Precise sealing design, worry free safety: The carbon dioxide steel cylinder is equipped with a professional grade high-pressure sealing valve group, using imported seals with excellent sealing performance, which can effectively prevent carbon dioxide gas leakage. The carbon dioxide cylinder valve group has a compact structure, easy operation, and is equipped with an overpressure protection device. When the pressure inside the cylinder exceeds the safety threshold, it will automatically release pressure, fundamentally ensuring the safety of the use process.
-Accurate pressure control and strong adaptability: Carbon dioxide steel cylinders are equipped with high-precision pressure gauges that can display the pressure inside the cylinder in real-time and accurately, making it convenient for users to keep track of the remaining gas volume and storage status at any time. Carbon dioxide steel cylinders can be matched with corresponding pressure reducing valves, flow meters, and other accessories according to the needs of different usage scenarios to achieve stable gas output and adapt to various equipment and process requirements.
-Standardized manufacturing, quality assurance: Designed, manufactured, and inspected strictly in accordance with relevant national standards such as GB5099. Each carbon dioxide cylinder undergoes multiple rigorous tests, including hydrostatic testing, airtightness testing, and non-destructive testing, and can only be shipped after passing the tests. Carbon dioxide steel cylinders have complete quality certificates and testing reports, with traceable and trustworthy quality.

Instructions for Use and Maintenance
Before using the carbon dioxide cylinder, please carefully check whether the appearance of the cylinder is intact, whether the valves, pressure gauges and other accessories are normal, and whether there is any leakage.
2. Carbon dioxide cylinders should be stored in a ventilated, dry, and cool place, away from sources of fire, heat, and flammable and explosive materials, and avoid direct sunlight and severe impact.
3. When operating carbon dioxide cylinders, they should be handled with care, and the opening and closing of valves should be done slowly. Rough operation is strictly prohibited.
4. The gas inside the carbon dioxide cylinder should not be completely exhausted, and a certain residual pressure should be retained to prevent air from entering the cylinder and causing pollution or affecting the next filling.
5. Regularly inspect carbon dioxide cylinders. According to relevant national regulations, high-pressure carbon dioxide cylinders should be inspected every 3 years to ensure safe use of the product.
