Anodized aluminum pipe, Dnepropetrovsk region.

"
Round anodized aluminum pipe is an independent product of rolled aluminum. Having a round cross-section, it is quite suitable for the role of a workpiece. Combining improved performance and technical characteristics, it is used in many areas of our everyday life. Anodizing qualitatively changes the functional property of an aluminum pipe, significantly expanding the scope of use. Method of production of anodized aluminum pipe. Anodizing is a complex electrochemical process. Depending on the size and thickness of the pipe, obtaining an oxide film on the surface of aluminum takes different time and has an individual chemical selection of components. The pipe is a universal product, so the process of processing the aluminum surface has industrial scales. So, the aluminum pipe is placed in a tank with acidic electrolyte. To start the reaction, an electric current is passed through the pipe. The higher the temperature in the tank, the thinner the oxide film will be, and conversely, the lower the temperature regime, the thicker the anodizing layer will be. The thin oxide layer is looser, which allows it to be painted with polymer dyes of any color. In some cases, the anodized product boils, which allows it to clog the pores in the pipe structure.(//tractor-service.com)
