Similarity criteria for modeling the process of pipes pulse pressing into the tube sheet

Abstract

In the presented article, the phenomena that characterize the essence of the process of fastening pipes to the tube sheet by the method of electropulse pressing are described. The article presents the results relating to methods and means of measurement, testing and operation of products in engineering, including theoretical studies of methods for fastening heat-exchange tubes into a tube sheet. The disadvantages of traditional methods of fastening pipes to the tube sheet are revealed. The analysis of the prospects of pipes electropulse pressing into the tube sheet is conducted. Using the dimensional analysis method, similarity criteria were obtained for the process of electropulse press-fitting of pipes into a tube sheet, which allow extending the results obtained on a reduced-scale model to products of natural dimensions.
