What is the Cause of Aluminum Pipe Cracking?

As a Modular Pipe System Manufacturer, share with you. The main cause of cracking of aluminum tubes is also due to the impurities contained. If this batch of aluminum material is to be stressed, it is recommended not to use it. If it is not conductive, it is recommended to use aluminum material in the future, which has high conductivity and good corrosion resistance.

Suggestions to prevent similar situations:

1. Improve the purity of the material and reduce the content of inclusions in the aluminum tube material matrix.

2. Improve the composition design, heating and aging annealing process, and reduce the content of delta ferrite in the aluminum tube material matrix.

3. Increase the number of end deformation passes, increase the deformation radius, reduce the difficulty of material deformation, promote uniform deformation of the material, and avoid excessive stress concentration.

4. If the finished material is not stressed, it will be deformed before aging (if the material is too bad, this will also happen if it is not aging).

Aluminum Pipe

The change rule of the corrosion morphology of the aluminum tube surface and determined the factors that have a greater impact on the corrosion of the aluminum tube; in order to explore the effect of salinity on the corrosion of the aluminum tube in the horizontal tube falling film evaporator, the seawater after evaporation and concentration is used as the corrosion medium In the horizontal tube falling film evaporator, the corrosion test of Aluminum Pipe was carried out. The change rule of the corrosion morphology of the aluminum tube surface was summarized and compared with the previous seawater corrosion experiment. The experimental results show that in the horizontal tube falling film evaporator, due to its special temperature and pressure environment, the aluminum tube is vulnerable to cavitation corrosion. The aluminum tube will be corroded after being used in the evaporator for a period of time. The main form of corrosion is pitting.

The aluminum tube should be maintained frequently:

1. When installing for the first time, make sure that the switch is flexible and smooth.

2. Pay attention to whether to install as required: the electric aluminum tube should put the door into the door hole during installation. If necessary, correct the surface of the wall to ensure that it can be installed in accordance with the regulations.

3. Pay attention to the regular maintenance during use: the maintenance of the aluminum tube cannot be ignored. For example, X-ray protection doors, even if they are made of corrosion-resistant metals such as stainless steel and lead, should still avoid contact with corrosive liquids in daily use.
