1. Inner wall treatment alulminum cylinder uses special inner surface treatment to ensure gas purity. 2. Specialty gases cylinder uses high-strength AA6061 material, which is light and durable with excellent pressure resistance. 3. High purity gases cylinder is suitable for high-demand industries such as electronics, medicine, and chemistry.

Product Introduction of standard gases cylinder: 

NETC's high purity gases cylinder uses advanced special inner surface treatment technology to improve the corrosion resistance of standard gases cylinder and the purity of gas storage. High purity gases cylinder uses a special inner surface treatment process to make the inner surface of the gas cylinder smoother and cleaner, effectively reducing gas pollution and being unaffected by external substances during storage and transportation. The aluminum alloy AA6061 material we use makes the gas cylinder both light and strong, suitable for specialty gases and calibration gases, etc.
