In the diploma thesis we worked on the connection the steel pipe with the steel pipe sheet by rolling. We tried to determine which pipe sheet is more suitable for a more reliable connection. We selected three different types of holes of tube sheet (holes without grooves, hole with one groove and a hole with two grooves), where the tube sheet were loaded under the same conditions. In the analysis of the results, we compare the performances of the tube sheets with each other, based on different criteria (radial stress, plastic deformation and thinning of the thickness of the pipe). We have found, that when the roller moves equally, the pipe sheet with a hole with two grooves better distributes the stress and deforms in places where it is necessary. The inside of the pipe sheet remains in the area of elastic deformations without any residual stress.
