5L oxygen machine molecular sieve aluminum cylinder tube Aluminum tube of oxygen concentrator is one of the pipeline materials used for transporting oxygen in oxygen production equipment. Aluminum tubes have the advantages of light weight, corrosion resistance, and ease of processing, and are commonly used in medical equipment. However, when choosing aluminum tubes as materials for oxygen concentrators, several factors need to be considered: Corrosion resistance: Although aluminum has good corrosion resistance, it may still be corroded in specific environments such as high humidity or environments containing corrosive substances. Therefore, it is very important to ensure proper surface treatment of aluminum tubes, such as anodizing treatment, which can improve their corrosion resistance and wear resistance. Thermal conductivity: Aluminum has excellent thermal conductivity, which may be advantageous in certain applications, but it may be necessary to control temperature changes in oxyge…
