Simulating the Rolling of Tubes and Its Effect on the Stressed and Strain State of the Tube Sheets Used in the Heat-Transfer Apparatuses of Steam Turbine Units

摘要

A comprehensive calculated and experimental investigation of the stresses occurring in the tube sheet of a shell-and-tube heat-transfer apparatus under the effect of tube rolling forces was carried out, the results of which were used to estimate the stressed and strain state of a tube bundle caused by technological loads, and it is shown that these loads need to be taken into account for carrying out a refined strength calculation.
