Anodised aluminum tubes is a process that uses aluminum or aluminum alloy products as anode, put them in electrolyte solution for electrifying treatment, and use electrolysis to form alumina film on their surface, which is called anodic oxidation treatment of aluminum and aluminum alloy. After anodizing, the oxide film on the surface of aluminum can be formed from several microns to several hundred microns. Compared with the natural oxide film of aluminum alloy, the corrosion resistance, wear resistance and decoration of the film are obviously improved.
Four advantages of anodized aluminum tubes:
1. corrosion resistance: the inner layer of air pipeline system is treated by anodizing, and the inner wall is smooth and dense Al2O3 protective layer. The outer wall is sprayed with special material dry powder, which makes the inside and outside not be corroded, and has strong acid and alkali resistance.
2. energy saving and consumption reduction: it is about 40% more than the cost of energy-saving pipeline, which is a relatively large part of the enterprise purchase cost. Low friction coefficient, unrestricted flow low initial pressure drop; lower load pressure, lower power consumption.
3. long life: aluminum alloy compressed air energy saving pipeline is safe and durable, and the design life of pipe fittings is more than 10 years, which can effectively avoid rust, high temperature aging cracking, even explosion of air compressor pipeline in enterprises.
4. easy installation: the energy-saving pipeline can be disassembled and reused, which is very suitable for your factory environment. The shunt device and branch pipeline are installed at any time quickly, which is convenient for the adjustment of production line.
Traditional pipeline
Defects of traditional pipeline
The outer layer and inner layer of seamless steel pipe are easy to be corroded in alkaline and local environment.
The inner wall of seamless steel pipe (traditional pipeline) is rough, and the connection is welded or tapped. It is not only easy to produce pressure drop and leakage at the connection, but also easy to corrode at the damaged part. With the increase of time, it is easier to reduce the inner diameter due to corrosion, increase the pressure drop and increase the leakage.
Anodized aluminum tube
Corrosion resistance of anodized aluminum tube:
The inner layer of anodized aluminum pipe system is anodized, and a very smooth and dense Al2O3 protective layer is formed on the inner wall. The outer wall is sprayed with dry powder of special materials (the effect of pipeline paint belongs to Mo grade), so that the inner and outer walls are not corroded for a long time, and have strong acid and alkali resistance.
The inner wall of the air pipeline system is smooth, and there is no pipe shrinkage between the pipes, which leads to very low pressure drop. The special connection seal and the non corrosiveness of the pipeline lead to no leakage, and the airpie pipeline system will not change the pressure loss due to the increase of time.
