Comparative analysis of technologies for cleaning finned bimetallic pipes of air cooling devices and methods for controlling contamination of the surface of aluminum alloys

Abstract

The results of the analysis of existing cleaning technologies for finned bimetallic pipes and methods for monitoring the contamination of the surface of aluminum alloys are presented and their disadvantages are established. It is shown that the technology used for cleaning pipes obtained by cold deformation is energy-consuming, ineffective and laborious, and the existing methods of contamination control do not provide a quantitative express assessment of the surface to be cleaned.
