Industrial and specialty gas cylinders use 6061 aluminum alloy, complying with GB/T 11640-2011 standard, ensuring consistent performance, wall thickness, and weight. The inner surface can be specially treated according to customer requirements, making it the preferred storage container for repeatedly filling various industrial gases, high-purity gases, specialty gases, and standard gases.
Carbon fiber wound composite cylinders are made using high-quality, high-efficiency carbon fiber filaments and high-strength aluminum alloy inner liners, processed with state-of-the-art equipment and advanced filament winding technology. Carbon fiber wound cylinders have excellent properties such as corrosion resistance, long service life, light weight, high strength, and non-fragility. Currently, these cylinders are gradually replacing traditional metal cylinders and are widely used in fire protection, chemical, mining, automotive, and other high-tech fields.
Aluminum alloy diving cylinders (self-contained underwater breathing apparatus), made from high-performance 6061 aluminum alloy. The inner surface of the cylinder undergoes a passivation treatment, ensuring that the stored gas is clean, corrosion-resistant, and odorless.
Sampling bottles are ideal equipment for sample collection and analysis. Our company's products are widely used in petrochemical, oil refining, wellsite analysis laboratories, alternative fuel technologies, and manufacturing. These products are made from 6061 aluminum alloy and 316 stainless steel; specifications, dimensions, and thread types can be customized to customer requirements.
Portable oxygen concentrators are small oxygen devices mainly used for personal healthcare, hospitals, high-altitude oxygen supplementation, and underground oxygen supply. They feature a simple, safe and reliable structure, large oxygen storage capacity, and long pressure retention time. They are equipped with a pressure gauge, pressure reducer, and flow meter. The oxygen cylinder is made of aluminum alloy, offering oxidation resistance and high-pressure tolerance, providing users with clean, fresh, rust-free oxygen.
