description: This work is devoted to the analysis of the literature database in the field of pipe steel production, as well as to the analysis of rolling modes of a sheet of pipe steel of strength category X100 to substantiate the technology of obtaining acicular ferrite. Tasks that were solved during the study: 1. Investigation of the features and conditions of AF formation in pipe steels of high strength categories. 2. Analysis of the dependencies of the volume fraction of AF on various parameters under controlled cooling. 3. Selection of the optimal mode of thermomechanical treatment to obtain the maximum amount of acicular ferrite. The work was carried out on the basis of a number of studies in the field of pipe steel production. Calculations were carried out showing clearly how the change of some parameters during controlled cooling affects the amount of acicular ferrite formed. The analysis was carried out by the method of mathematical modeling using the software "AusEvolPro" and "Stan 5000", equipped with databases of necessary parameters during thermomechanical processing. As a result, the end-to-end technology of production of pipe steel of the X100 strength category was analyzed, the parameters of thermomechanical processing and controlled cooling were calculated. The optimal mode of the controlled cooling pro- cess has been selected to obtain the maximum proportion of acicular ferrite in the conical microstructure of steel under the conditions of Stan 5000.
