DOT 气瓶

• SinoCleansky DOT gas cylinders are manufactured to the DOT-3AA standard. This cylinder type is primarily supplied to the South American and North American markets, backed by international third-party inspection reports.
• Certain sizes are widely used in welding and cutting applications—such as the 20CF and 40CF—and are also popular across the Middle East.
• Our DOT cylinders handle a broad range of gases, including Oxygen (O₂), Nitrogen (N₂), Argon (Ar), Carbon Dioxide (CO₂), Helium (He), Nitrous Oxide (N₂O), and Hydrogen (H₂), serving industrial, fire-fighting, energy, medical, urban infrastructure, and other sectors.

SinoCleansky DOT gas cylinders are commonly used for medical oxygen and a wide range of industrial gases. Building on the gas compatibility listed above, they serve:

• 医疗 — oxygen supply for hospitals and clinics

• 工业 — welding, cutting, and shielding gas in workshops

• Fire-fighting & energy — firefighting systems and energy-sector projects

• Urban infrastructure — city construction and utility projects
